The charger works well. It turns off everytime I use it with no problem. I trust it more then the 25amp version. I'm glad you get something out of the videos!

Pump, diesel heater, lights, charging points etc. I'm just hitting 40% now, mental amount of power so fat. I don't have my 1kw inverter wired in yet though.. Still blown away!!
Ive watched a ton of your videos in the last few weeks and have found them useful and informative. I'm just getting started in the Solar and Off Grid world. I made the mistake of buying a 2 amp charger for my 12v batteries. Takes forever at 30 watts. Just hope we start to get a bit more sun here in Ireland so i can charge faster that way. Keep up the good work
i like the idea that the Haisito charger has its own display with actual digits, not different color lights to show the state of charge. I have 2 NOCO chargers that do the job well but no digital display. I have to use digital volt meter to see the state of charge of the battery. I just clicked on the amazon link to check out the price wow they are giving that charger away. Im going to pick one up soon if they dont sell out. BTW i bought a batter disconnect the same one you did a video on. Works perfect thanks
Thanks for the comment! I really like this charger. You're right, the display is a nice bonus. Glad the hear the battery disconnect is working for you. It's a solid device!
These are also sold under other names such as HTRC. It's the usual, one Chinese factory putting out the same thing under different brands. Simply depends on what your local importer has on stock. These often go for 60 moneys (20A) or 40-50 (10 or 15A), depending on where you are.

hallo, trying to charge with 20 amp smart charger correctly set on minum current, my new LI TIME LiFePO4 100ah, the charger screen keeps stay off (standby) without recognize the battery, tester on positive and negative on battery reads 0,66v. disconnetting the charger the reading is 7,40v. more than 3 hours in this situation and i need from you advice on how to resolve. thank you
I was a little reluctant about this charger because of the fan noise but its actually quieter than I had thought. I had a Harbor Freight 2/8/15amp charger and it was loud.
If you need to overnight your charging, switching it to 5/10amps (depending on12v or 24v) quietens the fan down even further, put it on lowest setting(3A/5A) through the night and you'll hear nothing, brilliant little charger for twice the price point, at this price it's fantastic value for great kit!!! Winner 😊
Just bought one and out of the box when I plug it in it doesn't say OFF it says FUL without being connected to a battery yet. I try to select mode and nothing happens. It going back to Amazon and I won't buy another one. Going to buy a different brand
Thanks for pointing that out! The charger is not reporting that the battery is at 14.4v. The charger is showing that it's charging with a voltage of 14.4, not that the battery is 14.4v. The monitor is correct in showing the voltage of the battery is 13.5v. I didn't explain that correctly. Thanks again!
hi sir my car 12v Acidic Battery i charg in this device but now not showing my battery magic eay green indicator going to black now battery full charge but the magic eay green indicator not showing When put in the car for one day they battery again show green indicator it's why?
I apologize, but I'm not sure of the question. Is the battery that you are charging get to full charge then the green light shuts off? The display should show "FUL" when completely charged. Not sure why it would go black.
I'm a rookie...Could I use this while connected to shore power? Meaning my rv converter would be charging the battery and this would be connected directly to the same generator. Just worried about multiple charging sources.
You can definitely use it at the same time as the generator. Just make sure not to charge the batteries with too many amps. I would look to see what the max charge rate is for your bank, but you should be fine.
Looking at this unit for my Redodo 100aH in my MaxiTrac battery box. In a pinch could I charge the flooded lead acid battery in my camper trailer or is it limited to sealed lead acid? My priority of course is the LifePo4.
Question of the day… I currently have a pair of 2-way radio repeater at my lake house. One Motorola and one Hytera. I’m now using Trojan lead acid batteries with a hodgepodge of relays, contactors and chargers to power everything. The repeaters each have a 12vdc (11-14vdc) input (3amps RX / 14amps transmit). Can one of these chargers be left connected to a 12v 100ah LifePO4 battery CONTINUOUSLY? I have heard so many different opinions that have left me totally confused. Thanks!
Forgot… I don’t have any solar installed at the house yet, just utility AC power and a few portable Honda inverter type generators for use when we are there and experience a utility power outage. The utility AC supply is fairly decent. I upgraded from a 60a /240vac service to a 200 amp service when we bought the place decades ago. I ran a new underground service from the utility company’s pole a few thousand feet away and ran multiple 2” PVC conduits when I had the trench open.. for future use. Due to voltage drop. I ran doubled up 750kcmil copper feeders. It was a $$ fortune back in 1996, nowadays with the cost of Cu, it’d probably cost more than the drugs used to keep Biden awake each day. But only used that extra conduit capacity for a single FIOS fiber drop LOL.
Would i be able to plug that charger into the 110volt plug in my toyota sienna while its running and connect the charger to my agm 100ah house battery? The battery is currently hooked up to 200 watts of roof solar thru a charge controller. Could i use both solar and the Haisito charger at the same time? Is there a way to wire the Haisito charger to the solar charge controller at the same time as solar? I wonder if idling the van would use less fuel than buying a small gas generator to power the Haisito as an alternative to solar on cloudy days.
You can definitely use the charger along side the solar to charge the battery faster. I don't know what the power rating of the vehicle outlet is. You might have to lower the charging rate to accommodate for the amount of power the vehicle can product. I honestly don't see how the van would be more efficient than a small Genny, but it will work in a pinch. Thanks for the comment.
A true 20a charger would take 5 hours. I've never actually tested the time it takes for this charger to do the job. I always just set it and come back the next day. My guess would be 6 to 7 hours.
I've used the charger on my 12v and 24v systems and I've never had any issues. It's my go to charger. I like it better than the Hasito 25amp charger for the fact that it can also wake up Lifepo4 batteries.
Thanks for the video. Mine gets stuck on "Full" once it's fully charged my 12V LifePO4 100Ah battery. I have to switch it off to reset it. It doesn't kick in automaticallly to recharge the battery once the voltage drops. Is this normal? Thanks. I wanted to leave it permanently connected.
Man! the size of that 240W charger is small compared to my Bluetti charger, or my 12V 20A power supply. Can you check the power draw on the AC input side at full load to see how efficient this power supply is? Thanks. BTW, does it sense the battery Voltage first to see if the battery Voltage is not too low then it will only only come on if the battery is not too low? The reason I ask because if the LiFePO4 goes into low Voltage shutdown then the charger will not be able to wake up the battery since the charger will think that the battery Voltage is too low to safely charge the battery back up.
The battery charger is 72% efficient when running 19a at 12v. Do you know the efficiency of the bluetti charger? I haven't test if the charger has the "wakeup" feature, but someone on Amazon states that it does wake up a lifepo4 battery as long as the battery has 1v.
Ok if this is a test you failed to mention what amperage you set it at 24v you also failed to show what amps were produced by the charger. If you’re doing a test please do it right.
Yes. I don't believe you would have any problems doing that. I charge my 24v system with it while connected to solar and using DC lights and a 3k inverter. Works just fine for an extra boost to the battery. Thanks for the comment.
I bought this 20amp charger and a new redodo 100ah mini I went to charge first time selected Lifep04 at 20 amp but my charger never goes over 15 amps any thoughts ?
I think it's the charger. I have a 25A charger that does the same thing. It only charges at 21 amps. You could send it back, but think you will run into the same problem with other economy chargers.
So, a year later how is it doing ? initlal review don't mean much . One year later tell alot more. You, or anyone own this charger for a year...and how's it still performing ?
The charger still works, but the fan is starting to get louder. That worries me a bit. I use it now just for waking up batteries. Thanks for the comment.
Since I live in the U.S. I received the 110v model. I'm sure it comes in the 220v version as well. I found this on Amazon that shows the voltage input being 240v for the 20amp Haisito Charger. amzn.to/3O1IR8S I hope this helps. Thanks for the comment.
@@OffGridBasement I've been using these since the 23rd of May, works well, thanks. Have 24v system charging the batteries separately on 12v since the negative to system connected battery always seems to discharge a bit more. (and the fans are very load as you stated!)
Hi, is this as good as the Haisito?. Does it switch back on batteries?, also does it maintain the battery if it gets low by automatically start charging?. I'm not sure which to get, the Haisito or the HTRC. Appreciate the videos on these, thanks.
I have the exact same charger. My observation, is that when the charger completes charging, it spikes up to 29volts for a second and then shuts off... I'm afraid it will damage my battery. I noticed this, when my inverter went into protection mode, every time charging is completed. Power off/on the inverter and everything is okay, but the voltage spike is a concern. Is it possible I have a bad charger?
As I've commented on your other video, these chargers (Haisito/HTRC, same unit, and this includes the P35) do NOT terminate charging properly on LiFePO4, they don't seem to go into the different modes listed in the manual, they just go full blast at whatever they're set (which, as you know, is not accurate on top speed) and then abruptly stop and display FULL. As such, you're not able to fully charge LiFePO4 batteries with these chargers. If you're building an in-series multi-battery unit, you won't be able to top them off to start with a balanced set by using these chargers.
can i connect two lithium lifePO4 100ah batteries in series to produce 24 volts (for my trolling motor) and charge them with my 20 amp haisito charger ( the identical one you have in this video) simultaneously? It s Walt from Idaho.
one more question please. If, when my two batteries are in series, and in use with my trolling motor, if I attach the haisito charger to the batteries, will it monitor the battery strength without being plugged into AC?
@@OffGridBasement that is amazing and thank you! i am using 2 12v 7ah battery's for 24v and needed a charger! google was not useful so i turned to RUclips and that's also how i found my motors lol but anyway thank you for making this so much easier!
@@OffGridBasement Awesome you responded first time a RUclipsr actually responds to my comment. I have another question it may be stupid but I can't find a definite answer. If I have two 12v LifePo4 batteries and I wire them in series can I charge it with 24V?
all said and done, the best thing to prolong the chargers life is to replace that cheap fan before it dies to keep from burning up a good charger. I used to biuld gaming PC's fans are not very expensive. Maybe I will get one and then see what size that fan is, or if nothing else mount a slightly larger better quality fan in front or behind it depending on which way the fan moves the air. I have a lot of 120 mm fans I may just use one of them after mounting it on a piece of plywood that the charger can sit on also. I know those will be bigger, but air is air.
@@chadwolfeschledgelsteinhau9697you should be able to run 2 of these chargers with a 2k generator. Because of this comment I made a video. Stay tuned! Coming out this week!
I got the Haisito version and for 24V Lifepo4 it only does 8.7amps not 10. Similar to your 17a with 12v. Amzn reviews comment on this deficiency (lie) too.
Ive got the HTRC P20, exactly the same unit, been wondering if its man enough or too high on the voltage, between this and several other videos this a.m, allmy concerns have evaporated, phew, dont need another charger then!! Very well priced for what it is, happy days!!
@@OffGridBasement no problem man, thanks for the videos, I'm just a joiner with some crimps, it's nice to get experience and knowledge from real world peoples my man, have a great one 😊🙏
it depends on the size of the battery. A 100ah lifepo4 battery usually like around 20 amps of charging current. Anything lower definitely won't hurt the battery. It will just take longer to charge. I hope this helps. Thanks for the comment.
In general, you shouldn't choose more than half the current than the battery has capacity, for example 25A for a 50Ah battery. You can of course charge LiFePo4 batteries with their rated maximum charging current which is usually equal to capacity, but it shortens the lifespan a little due to thermal stress. The manufacturers themselves recommend half that.
The monitor just keeps track of the amount of electricity going through the wires. I bought it on Amazon. Here is a link: amzn.to/3REGVCs Thanks for the question!
Does it still work? I just bought what appears to be the same one with a different name. I guess they are all chinese manufacture. A lot of comments saying the longevity of the charger ranges from weeks to a few months. Is yours still going strong?
Hi. Have you charged your 24v battery with this charger with out the smaller 12v battery if so how long would it take to fully charge the 24v battery's.
If the 24v system was completely depleted and I didn't have any loads on it, it would take around 35 hours to completely charge with the Hasito charger. Hope that answers your question. Thanks for the comment.
Your Hasito is identical to my HTRC. Which is also identical to the DGHT, & the Nexpeak. Appears they are all the same unit produced by the same manufacture under different names. My only complaint is the HTRC has no customer support. No phone number or e-mail to contact about operation, questions, parts, or warranty. Maybe you get that with the Hasito?
Will consider it if i need one. . My POWmr came FedEx nice so reputable from some suppliers at Aliexpress. But a catch. Will not power up with no battery connected. So maybe don't get orange one get light blue model. But also light blue one needs at lease 130v of solar where orange one only needs 90 vdc. I think voc values. ,
@@OffGridBasement Well it should be OK., just as I said batteries are coming but could be another few weeks. It should power on WITH battery. but yeah can't use it till battery arrives.
I need a charger to charge a 100ah and a 18ah lifepo4 batteries for my fishing boat. Is this a safe charger? I don’t know anything about these type of batteries and im scared to buy something that’s going to Burt’s into flames or something. Lol
I use this charger all the time for my 100ah lifepo4 batteries. I think it would work well for you because you can slow down the charging rate for the 18ah battery. Good luck and have fun!
Hello. Nice setup you got there 👍 I have the same battery charger. I read most of the comments regarding not getting the full 20 amps charging. Same on this side. I get close to 16 amps on a Li time LifePo4 mini 12V 100Ah. Took 7 hours to charge. I am thinking about getting a 40 or 50 amp charger for certain occasions when I need to charge faster. I am running 2 of these batteries in parallel. Any suggestions?
I've never reviewed a charger over 30A. I would go with something that has a metal housing. Not plastic. Don't know of a specific brand though. Sorry I can't tell you more.
@@OffGridBasement They actually make a 35V same style as the 20 you (and I) both have. Plastic housing. I agree on the metal housing. May search further for something. I would be using more at home. The 20 for mobile purposes
I didnt want buy this unit because i didnt think it does what it says. Lithium and lipo charging is 29.2 29.4. But i saw in the comments it charges 29v so i might consider....
It's only pushing 20amps from the DC side. 20A @ 12.8 volts 256w. 256w on the 120v AC side would be 2.13amps. I hope that is clear. Thanks for the thumbs up!
There are plenty of better chargers out there. I'm still using this one, but the fan is starting to get loud. I really like it b/c the fact that it can "wake up" a dead Lifepo4 battery, unlike other smart chargers. Thanks for the comment.
In your 24v charging scenario, it looks to me that you weren't really "charging" your 24v batteries. The power from your charger was just providing some of the power to the load and therefore reduced the current coming from your 2 batteries but no charging of the batteries actually occurred. The batteries were still discharging, but at a lower rate. That is my understanding of what is happening in this situation because batteries don't charge and discharge simultaneously, but it kind of looks like that is what is happening. You even said that "the charger is taking some of that DC power away." And on your computer monitor it shows that the battery is still discharging, not charging. So that scenario is not technically showing charging, but the charger is load sharing. Just checking if my understanding of what is happening is correct. Still learning... Thanks for your video. It looks like a good charger. Thinking about getting one. Edit: After thinking about it more, you also demonstrated a way to load share the power from a 12 volt battery into a 24 volt system without taking your 24 volt system apart in any way. Such as if you needed to get a little more power during the night in a power outage situation to get you through until some solar could start providing power again in the morning. Not necessarily great efficiency, but it could work in an emergency situation.
Great observation! That is exactly what is occurring. I was only lessening the discharge rate of my 24v battery bank. I've got a series of videos that started coming out today about the exact scenario you are talking about! I've created a 12v bank of random lifepo4 batteries and I'm going to use it to supplement my 24v system. Great insight! Thanks for the comment and info.
I just bought this then seen your review..it charging my LiTime 100AH for my trolling motor..thanks for the review..first lithium battery for me..not sure what to look for but l'll figute it out..
You will be happy with the battery. Just charge it using the Lifepo4 setting. Not sure the amount of power your trolling motor draws, but it should last all day. The charger will turn off as soon as it's full. That should be around 14.6v. the battery will then settle down to about 13.6v. Good luck and enjoy!
I bought this on your recommendation and it has been great! But I am only ever getting a max of 15 amps. It never actually hit 20 amps. I tried it on two different LiFePO4 batteries - same result. I noticed the highest you got in the video was 17.8 amps. Is this normal?
I think I figured out why. This charger is multi-use for different batteries INCLUDING LFP, so the 20A delivery rating is actually at 12V. This means the max output is around 240W. When the charger is outputting to a LiFePO4 battery at 14.6V (instead of 12V), the maximum power output drops to around 15-16A total. Does this make sense?
@@theq-ster6981 Lead acid charge at higher voltage than 12V as far as I know. I am thinking this is possibly due to how hot the unit runs and limits its current when too hot. Mine shows 45c and I have seen other people here are at about 30c?
It's self regulating depending on temperature.. If you hear the fan come on. You know it's going to lower charge rate.. This is how most Chargers work... And I can tell you fro experience. My NOCO 10amp goes down to like 2 amps and the wire gets super hot. It once melted..
Beware when your 24V battery wont charge when the auto sensing mode in this type of charger says fully charged in the 12V mode. These need a 12V or 24V manual switch. Very worthless while trying to charge a low voltage 24V battery. 😖
This charger still works well for me. Some of the other Hasito chargers I've reviewed have started to have issues. I plan on making a follow-up video on the issues. Thanks for the comment.

hallo,
trying to charge with 20 amp smart charger correctly set on minum current, my new LI TIME LiFePO4 100ah, the charger screen keeps stay off (standby) without recognize the battery, tester on positive and negative on battery reads 0,66v. disconnetting the charger the reading is 7,40v. more than 3 hours in this situation and i need from you advice on how to resolve.
thank you
If your battery is reading 7.4v then it has something wrong. It could possibly be a bad BMS or some balancing leads are disconnected inside the case.
I was a little reluctant about this charger because of the fan noise but its actually quieter than I had thought. I had a Harbor Freight 2/8/15amp charger and it was loud.
It is also quiet compared to the P10X2 charger. That fan is loud in comparison! Thanks for the comment.
If you need to overnight your charging, switching it to 5/10amps (depending on12v or 24v) quietens the fan down even further, put it on lowest setting(3A/5A) through the night and you'll hear nothing, brilliant little charger for twice the price point, at this price it's fantastic value for great kit!!! Winner 😊

Bummer it didn't work out for you.
I guess would it be safe to say that you can be using power from your lifepo4 battery at the same time it is being charged by this batt charger?
Yes. I do it all the time without issue. Thanks for the comment.
9:20 I didn't get it. The charger shows 14.4V while the monitor shows 13.5V - is it even ok?
Thanks for pointing that out! The charger is not reporting that the battery is at 14.4v. The charger is showing that it's charging with a voltage of 14.4, not that the battery is 14.4v. The monitor is correct in showing the voltage of the battery is 13.5v. I didn't explain that correctly. Thanks again!
Is 13.5V enough? Do you recommend a charger that fully charges?
hi sir my car 12v Acidic Battery i charg in this device but now not showing my battery magic eay green indicator going to black now battery full charge but the magic eay green indicator not showing When put in the car for one day they battery again show green indicator it's why?
I apologize, but I'm not sure of the question. Is the battery that you are charging get to full charge then the green light shuts off? The display should show "FUL" when completely charged. Not sure why it would go black.
I'm a rookie...Could I use this while connected to shore power? Meaning my rv converter would be charging the battery and this would be connected directly to the same generator. Just worried about multiple charging sources.
You can definitely use it at the same time as the generator. Just make sure not to charge the batteries with too many amps. I would look to see what the max charge rate is for your bank, but you should be fine.
I got the p15 model of that same charger and it works real well
Good to hear!
Can you charge an eight 12v battery bank (24v 2s/4p) with this charger?
You can. It will take a long time. Consider getting a larger unit.
@@OffGridBasement what would you recommend for a bank of 24 volts and 400amps (8-12v 100ah batteries 2s/4p) ?
Clamp cables seem a bit thin for 20A
They get a bit warm, but nothing to be alarmed about. Thanks for the comment.
Looking at this unit for my Redodo 100aH in my MaxiTrac battery box. In a pinch could I charge the flooded lead acid battery in my camper trailer or is it limited to sealed lead acid?
My priority of course is the LifePo4.
You can charge the flooded battery with the AGM setting on the charger. Hope that helps. Thanks for the comment.
Question of the day…
I currently have a pair of 2-way radio repeater at my lake house. One Motorola and one Hytera.
I’m now using Trojan lead acid batteries with a hodgepodge of relays, contactors and chargers to power everything.
The repeaters each have a 12vdc (11-14vdc) input (3amps RX / 14amps transmit).
Can one of these chargers be left connected to a 12v 100ah LifePO4 battery CONTINUOUSLY?
I have heard so many different opinions that have left me totally confused.
Thanks!
Forgot… I don’t have any solar installed at the house yet, just utility AC power and a few portable Honda inverter type generators for use when we are there and experience a utility power outage.
The utility AC supply is fairly decent. I upgraded from a 60a /240vac service to a 200 amp service when we bought the place decades ago. I ran a new underground service from the utility company’s pole a few thousand feet away and ran multiple 2” PVC conduits when I had the trench open.. for future use.
Due to voltage drop. I ran doubled up 750kcmil copper feeders. It was a $$ fortune back in 1996, nowadays with the cost of Cu, it’d probably cost more than the drugs used to keep Biden awake each day.
But only used that extra conduit capacity for a single FIOS fiber drop LOL.
No. I would get a small 3A trickle charger \ maintainer. This unit doesn't maintain after a full charge. Hope this helps.
Hi. I have this charger did your one come with cable lugs if so how do i connect it.
I believe mine only came with battery clamps. Are you trying to connect to a SLA battery?
Would i be able to plug that charger into the 110volt plug in my toyota sienna while its running and connect the charger to my agm 100ah house battery? The battery is currently hooked up to 200 watts of roof solar thru a charge controller. Could i use both solar and the Haisito charger at the same time? Is there a way to wire the Haisito charger to the solar charge controller at the same time as solar? I wonder if idling the van would use less fuel than buying a small gas generator to power the Haisito as an alternative to solar on cloudy days.
You can definitely use the charger along side the solar to charge the battery faster. I don't know what the power rating of the vehicle outlet is. You might have to lower the charging rate to accommodate for the amount of power the vehicle can product. I honestly don't see how the van would be more efficient than a small Genny, but it will work in a pinch. Thanks for the comment.
Thanks for your quick reply and for a great video. Cheers.
Can you do a test with it to see how long it takes to charge that 100 amp hour battery
A true 20a charger would take 5 hours. I've never actually tested the time it takes for this charger to do the job. I always just set it and come back the next day. My guess would be 6 to 7 hours.
4 to 5 hours,
I need to know if this actually charges at the right voltage. Not a system thats also on solar.
I've used the charger on my 12v and 24v systems and I've never had any issues. It's my go to charger. I like it better than the Hasito 25amp charger for the fact that it can also wake up Lifepo4 batteries.
Thanks for the video.
Mine gets stuck on "Full" once it's fully charged my 12V LifePO4 100Ah battery.
I have to switch it off to reset it.
It doesn't kick in automaticallly to recharge the battery once the voltage drops.
Is this normal? Thanks.
I wanted to leave it permanently connected.
I believe that is normal. I don't think it has a trickle charge function for after the battery is full. Thanks for the comment.
Man! the size of that 240W charger is small compared to my Bluetti charger, or my 12V 20A power supply.
Can you check the power draw on the AC input side at full load to see how efficient this power supply is? Thanks.
BTW, does it sense the battery Voltage first to see if the battery Voltage is not too low then it will only only come on if the battery is not too low? The reason I ask because if the LiFePO4 goes into low Voltage shutdown then the charger will not be able to wake up the battery since the charger will think that the battery Voltage is too low to safely charge the battery back up.
The battery charger is 72% efficient when running 19a at 12v. Do you know the efficiency of the bluetti charger?
I haven't test if the charger has the "wakeup" feature, but someone on Amazon states that it does wake up a lifepo4 battery as long as the battery has 1v.
@@OffGridBasement I will test it and report back, my Bluetti is EB70.
Ok if this is a test you failed to mention what amperage you set it at 24v you also failed to show what amps were produced by the charger.
If you’re doing a test please do it right.
Thanks for the tip! I'll update my videos in the future.
Hi, can this charger turn off it's screen when the battery is full charged?
Unfortunately no. The only way to turn it off is by unplugging the unit.
Can this be use at the same time the battery is being charge from solar via pwm controller while powering a 12v fridge.
Yes. I don't believe you would have any problems doing that. I charge my 24v system with it while connected to solar and using DC lights and a 3k inverter. Works just fine for an extra boost to the battery. Thanks for the comment.
What setting do I use to wake up my BMS (battery dormant) from a LiFePO4 12.8V 100amp EcoWorthy battery?
You should be able to use the "lifepo4" setting to wake up the BMS if it has been completely discharged.
@@OffGridBasement Thank you very much - it worked so far.
I bought this 20amp charger and a new redodo 100ah mini I went to charge first time selected Lifep04 at 20 amp but my charger never goes over 15 amps any thoughts ?
I think it's the charger. I have a 25A charger that does the same thing. It only charges at 21 amps. You could send it back, but think you will run into the same problem with other economy chargers.
So, a year later how is it doing ? initlal review don't mean much . One year later tell alot more. You, or anyone own this charger for a year...and how's it still performing ?
The charger still works, but the fan is starting to get louder. That worries me a bit. I use it now just for waking up batteries. Thanks for the comment.
Would like to know if this charger can be plugged into 220-250V systems...
Since I live in the U.S. I received the 110v model. I'm sure it comes in the 220v version as well. I found this on Amazon that shows the voltage input being 240v for the 20amp Haisito Charger. amzn.to/3O1IR8S
I hope this helps. Thanks for the comment.
@@OffGridBasement Got it, thank you!
@@OffGridBasement I've been using these since the 23rd of May, works well, thanks. Have 24v system charging the batteries separately on 12v since the negative to system connected battery always seems to discharge a bit more. (and the fans are very load as you stated!)
Hi, is this as good as the Haisito?. Does it switch back on batteries?, also does it maintain the battery if it gets low by automatically start charging?. I'm not sure which to get, the Haisito or the HTRC. Appreciate the videos on these, thanks.
The haisito will maintain once it's full, but it won't start up a full charge cycle automatically. It needs to be reconnected.
I have the exact same charger. My observation, is that when the charger completes charging, it spikes up to 29volts for a second and then shuts off... I'm afraid it will damage my battery. I noticed this, when my inverter went into protection mode, every time charging is completed. Power off/on the inverter and everything is okay, but the voltage spike is a concern. Is it possible I have a bad charger?
It could be. I've never had an issue with the charger, but I've never used it while connected to the inverter. Thanks for the info and the comment.
battery 24v 100ah Lifepo4, charger 20 amperes is it normal or is it very strong ampers?
A 24v 20A charger would be the best way to go. You could probably go up to a 50A charger if needed. Hope this helps. Thanks for the comment.
@@OffGridBasement Thank you so much
So I can charge a lithium 12v 100 ah
Yes you can.
As I've commented on your other video, these chargers (Haisito/HTRC, same unit, and this includes the P35) do NOT terminate charging properly on LiFePO4, they don't seem to go into the different modes listed in the manual, they just go full blast at whatever they're set (which, as you know, is not accurate on top speed) and then abruptly stop and display FULL. As such, you're not able to fully charge LiFePO4 batteries with these chargers. If you're building an in-series multi-battery unit, you won't be able to top them off to start with a balanced set by using these chargers.
Yes. I read the other comment. It's true that these chargers don't really absorb. They get up to 14.6v then turn off.
Charger link is not working
Looks like Haisito doesn't sell this charger any longer. That's a bummer. You should check HTRC's version of the charger instead. amzn.to/3SN9leS
This charger still holding up? 1 year update?
Yes! The 25A Haisito charger... Not so much. Hope this helps.
can i connect two lithium lifePO4 100ah batteries in series to produce 24 volts (for my trolling motor) and charge them with my 20 amp haisito charger ( the identical one you have in this video) simultaneously? It s Walt from Idaho.
Yes! That would be a great way to go. Thanks for the comment.
you are fantastic. your video was very informative and easy to follow. But more important you gave me an answer within hours. Continued success!!!
one more question please. If, when my two batteries are in series, and in use with my trolling motor, if I attach the haisito charger to the batteries, will it monitor the battery strength without being plugged into AC?
200 amp lifepo4 akü için hangi şarj cihazını satın alabilirim?
this charger will work for LifePo4. It will take 10 hours to charge from 0 - 100%.
Thank you brother 🙏
How long does it take to charge a redodo 12v 100ah?
With a 20 amp charger it takes about 5 hours. With a 50 amp charger it would take 2 hours. Hope this helps and thanks for the comment.
can i use it as a onboard charger for my 24v ebike?
I don't see why not. You would just need the proper connection.
@@OffGridBasement that is amazing and thank you!
i am using 2 12v 7ah battery's for 24v and needed a charger!
google was not useful so i turned to RUclips
and that's also how i found my motors lol
but anyway thank you for making this so much easier!
@@MPCLStudios you're welcome! Good luck!
Will this be good to charge a smaller 12 volt 7 ah battery
Maybe at the lowest setting. You don't want to push too many amps into that small of a battery.
Anyone else charger not work. just says OFF and flashing battery on top left of screen
Mine still works well. Sounds like there is something going on with your clamps. Not sure.
@@OffGridBasement Awesome you responded first time a RUclipsr actually responds to my comment.
I have another question it may be stupid but I can't find a definite answer. If I have two 12v LifePo4 batteries and I wire them in series can I charge it with 24V?
Yes. Remember you need to have the two batteries balanced with one another in order to get a full charge to both batteries.
all said and done, the best thing to prolong the chargers life is to replace that cheap fan before it dies to keep from burning up a good charger. I used to biuld gaming PC's fans are not very expensive. Maybe I will get one and then see what size that fan is, or if nothing else mount a slightly larger better quality fan in front or behind it depending on which way the fan moves the air. I have a lot of 120 mm fans I may just use one of them after mounting it on a piece of plywood that the charger can sit on also. I know those will be bigger, but air is air.
Good idea. I really need to look into replacing the fan. Getting a bit loud.
What is the brand of that 12 V battery that you were using with the AC plug built into it
It's just a DIY power station I built. Here is a link to the video: ruclips.net/video/NsUMleJwkO0/видео.html
How much does the charger draw?
Without anything connected it draws 1.5w. it is around 78% efficient. Hope this helps and thanks for the comment.
@@OffGridBasement ok so my 2k watt generator can run 1 but not 2?
@@chadwolfeschledgelsteinhau9697you should be able to run 2 of these chargers with a 2k generator. Because of this comment I made a video. Stay tuned! Coming out this week!
@@OffGridBasement will do
@@OffGridBasement and yay!
I got the Haisito version and for 24V Lifepo4 it only does 8.7amps not 10. Similar to your 17a with 12v. Amzn reviews comment on this deficiency (lie) too.
Yep. The only charger I have tested so far that give out 100% are the pure lifepo4 chargers. Definitely not the all battery smart chargers.
Great video, I purchased one ( Dave, U.K )
I still use this charger every week. Works well!
@OffGridBasement What would you recommend the setting on that battery charger to charge up a 24v 100ah Lifepo4 battery ?
Ive got the HTRC P20, exactly the same unit, been wondering if its man enough or too high on the voltage, between this and several other videos this a.m, allmy concerns have evaporated, phew, dont need another charger then!! Very well priced for what it is, happy days!!
I still use it all the time and have never had a problem! Thanks for the comment.
@@OffGridBasement no problem man, thanks for the videos, I'm just a joiner with some crimps, it's nice to get experience and knowledge from real world peoples my man, have a great one 😊🙏
Thnx for this
Does it matter what current we choose?
Is a lower current better for the battery life?
it depends on the size of the battery. A 100ah lifepo4 battery usually like around 20 amps of charging current. Anything lower definitely won't hurt the battery. It will just take longer to charge. I hope this helps. Thanks for the comment.
In general, you shouldn't choose more than half the current than the battery has capacity, for example 25A for a 50Ah battery.
You can of course charge LiFePo4 batteries with their rated maximum charging current which is usually equal to capacity, but it shortens the lifespan a little due to thermal stress. The manufacturers themselves recommend half that.
Would this also work on 12v 10ah lifepo4 battery?
It would, but it would charge the battery really fast, even at 5 amps. I wouldn't recommend it.
I wish when it was done charging I could scroll through andsee how many ah's got put in the battery....just says full
That would be a really nice feature.
What is the little monitor and where can I get one from?
The monitor just keeps track of the amount of electricity going through the wires. I bought it on Amazon. Here is a link: amzn.to/3REGVCs
Thanks for the question!
Does it still work? I just bought what appears to be the same one with a different name. I guess they are all chinese manufacture. A lot of comments saying the longevity of the charger ranges from weeks to a few months. Is yours still going strong?
I'm actually using it right now to charge a 24v 100ah battery! Still works. The fan is starting to make some noise which is concerning.
merry Christmas, one question: can this charger work with cellular type battery pack??? thanks!!!
Unfortunately not. The voltage would be too high.
Hi. Have you charged your 24v battery with this charger with out the smaller 12v battery if so how long would it take to fully charge the 24v battery's.
If the 24v system was completely depleted and I didn't have any loads on it, it would take around 35 hours to completely charge with the Hasito charger. Hope that answers your question. Thanks for the comment.
@@OffGridBasement Thank you. Keep up the good work.
Your Hasito is identical to my HTRC. Which is also identical to the DGHT, & the Nexpeak. Appears they are all the same unit produced by the same manufacture under different names. My only complaint is the HTRC has no customer support. No phone number or e-mail to contact about operation, questions, parts, or warranty. Maybe you get that with the Hasito?
I did, but not much anymore. I think my contact moved to a different company.
Will consider it if i need one. . My POWmr came FedEx nice so reputable from some suppliers at Aliexpress. But a catch. Will not power up with no battery connected. So maybe don't get orange one get light blue model. But also light blue one needs at lease 130v of solar where orange one only needs 90 vdc. I think voc values. ,
That is a bummer. Do you plan on returning it?
@@OffGridBasement Well it should be OK., just as I said batteries are coming but could be another few weeks. It should power on WITH battery. but yeah can't use it till battery arrives.
No battery inverters sound great, but cloudy days will cycle inverter on and off constantly, not very good for its health
I need a charger to charge a 100ah and a 18ah lifepo4 batteries for my fishing boat. Is this a safe charger? I don’t know anything about these type of batteries and im scared to buy something that’s going to Burt’s into flames or something. Lol
I use this charger all the time for my 100ah lifepo4 batteries. I think it would work well for you because you can slow down the charging rate for the 18ah battery. Good luck and have fun!
@@OffGridBasement awesome. Thanks for helping me out. I didn’t know what to do.
Hello. Nice setup you got there 👍 I have the same battery charger. I read most of the comments regarding not getting the full 20 amps charging. Same on this side. I get close to 16 amps on a Li time LifePo4 mini 12V 100Ah. Took 7 hours to charge. I am thinking about getting a 40 or 50 amp charger for certain occasions when I need to charge faster. I am running 2 of these batteries in parallel. Any suggestions?
I've never reviewed a charger over 30A. I would go with something that has a metal housing. Not plastic. Don't know of a specific brand though. Sorry I can't tell you more.
@@OffGridBasement They actually make a 35V same style as the 20 you (and I) both have. Plastic housing. I agree on the metal housing. May search further for something. I would be using more at home. The 20 for mobile purposes
I didnt want buy this unit because i didnt think it does what it says. Lithium and lipo charging is 29.2 29.4. But i saw in the comments it charges 29v so i might consider....
I charge my 12v and 24v systems with it and I've never had a problem. Thanks for the comment.
The only real surprise/shock is the gauge of the AC side wire …. 😳 Seem Awfully Small for pulling 20A ….
Thanks for the Vid ! 👍🏼
It's only pushing 20amps from the DC side. 20A @ 12.8 volts 256w. 256w on the 120v AC side would be 2.13amps. I hope that is clear. Thanks for the thumbs up!
AC input is pushing like 2 amps. Then converted to 12 volt 20 amps...So the AC gauge wire size is not relevant..
Thanks for the Clarification(s) …. Always learning 🤓
I looked at getting one of those chargers, but their is just too many bad reviews for them.
There are plenty of better chargers out there. I'm still using this one, but the fan is starting to get loud. I really like it b/c the fact that it can "wake up" a dead Lifepo4 battery, unlike other smart chargers. Thanks for the comment.
@@OffGridBasement right, the only problem is, is they want 15 to 20 times more for them.
HI! thanks for the review!
one question...at what voltage does the charger stop with a 24v lifepo4 battery?
greetings from Italy 😉🇮🇹
It stops at 29v. Thanks for the question.
This is what I needed to know
In your 24v charging scenario, it looks to me that you weren't really "charging" your 24v batteries. The power from your charger was just providing some of the power to the load and therefore reduced the current coming from your 2 batteries but no charging of the batteries actually occurred. The batteries were still discharging, but at a lower rate. That is my understanding of what is happening in this situation because batteries don't charge and discharge simultaneously, but it kind of looks like that is what is happening. You even said that "the charger is taking some of that DC power away." And on your computer monitor it shows that the battery is still discharging, not charging. So that scenario is not technically showing charging, but the charger is load sharing. Just checking if my understanding of what is happening is correct. Still learning...
Thanks for your video. It looks like a good charger. Thinking about getting one.
Edit: After thinking about it more, you also demonstrated a way to load share the power from a 12 volt battery into a 24 volt system without taking your 24 volt system apart in any way. Such as if you needed to get a little more power during the night in a power outage situation to get you through until some solar could start providing power again in the morning. Not necessarily great efficiency, but it could work in an emergency situation.
Great observation! That is exactly what is occurring. I was only lessening the discharge rate of my 24v battery bank. I've got a series of videos that started coming out today about the exact scenario you are talking about! I've created a 12v bank of random lifepo4 batteries and I'm going to use it to supplement my 24v system. Great insight! Thanks for the comment and info.
I just bought this then seen your review..it charging my LiTime 100AH for my trolling motor..thanks for the review..first lithium battery for me..not sure what to look for but l'll figute it out..
You will be happy with the battery. Just charge it using the Lifepo4 setting. Not sure the amount of power your trolling motor draws, but it should last all day. The charger will turn off as soon as it's full. That should be around 14.6v. the battery will then settle down to about 13.6v. Good luck and enjoy!
I bought this on your recommendation and it has been great! But I am only ever getting a max of 15 amps. It never actually hit 20 amps. I tried it on two different LiFePO4 batteries - same result. I noticed the highest you got in the video was 17.8 amps. Is this normal?
I've seen 20 amps once with charging a 12v 275ah lifepo4 battery from under 10%. Most of the time I get between 15 and 17 amps.
same here... only have seen 15.2A so far
I think I figured out why. This charger is multi-use for different batteries INCLUDING LFP, so the 20A delivery rating is actually at 12V. This means the max output is around 240W. When the charger is outputting to a LiFePO4 battery at 14.6V (instead of 12V), the maximum power output drops to around 15-16A total. Does this make sense?
@@theq-ster6981 Lead acid charge at higher voltage than 12V as far as I know.
I am thinking this is possibly due to how hot the unit runs and limits its current when too hot. Mine shows 45c and I have seen other people here are at about 30c?
It's self regulating depending on temperature.. If you hear the fan come on. You know it's going to lower charge rate.. This is how most Chargers work...
And I can tell you fro experience. My NOCO 10amp goes down to like 2 amps and the wire gets super hot. It once melted..
Beware when your 24V battery wont charge when the auto sensing mode in this type of charger says fully charged in the 12V mode. These need a 12V or 24V manual switch. Very worthless while trying to charge a low voltage 24V battery. 😖
Thanks for the info and the comment.
Same charger on eBay is much less $$
