Does this charger need to detect that the battery has Voltage present before the charging circuit will come on? If it does then you cannot use it to wake up the battery's BMS when the BMS is in shutdown mode. I would be reluctant to trust that it really knows what type of battery chemistry it knows, especially if the De-sulfate function is really disabled when charging LFP. Do you have the link to download PDF User manuals? BTW, do you have the way to verify that it can actually detect the dead 24V battery bank with really low Voltage and able to charge know that it is 24V battery not 12V if the Voltage of the 24V battery is really low.
I just checked on a dead 12v lifepo4 battery and it does NOT wake up the battery. The 20A Hasito charger woke up the battery just fine. With all the problems I had with this charger I do not recommend it. If you want a Hasito charger, get the 20A!
@@OffGridBasement It is great that you test that function out since most smart charger cannot wake up BMS, you can add this test function into your charger review, most review does not test this function. I really like your channel and always looking forward to your next video.
@@budmartin3344 I should make a video solely on if a charger can wake a lifepo4 battery. Also on other ways to wake it up. I'm glad you like the channel. Thanks for watching!

I was charging my 100AH LFP battery with a 20A charger that uses 9 stages. This battery has bluetooth and was watching the charging time left. Once the battery got to 99 percent charge the time left starting slowly increasing. Was this due to the dropping level of the Amp input? I was not for sure what was happen and stopped the charging. Why was time left for full charge increasing? I was using a HTRC 20A charger.
I don't know if this question has been asked/answered. Will charging resume after a power outage without human input? Because my cccvv bench supplies do.
Yes. It will act the same way. It remembers the last settings before the power outage and resumes the charging. Hope this helps and thanks for the comment.
Mine was from the same manufacturer and although it 2as a 10Amp charger it did go over 9 Amps when the 12v 65A battery was accidentally discharged to below 10vdc but only that once! It didn't go over 6A after pulsing or when it went to 10.6 when after fully discharged to my backup power supplyvia a victron12/24 DC TO DCpower supply setting. It didnt last six months of doing 5gat and now it comes up with ERO (error) message and nothing gets past that!
Ok so I know nothing or very little about lifpo4 bms batteries but I got one in to do a review on. But since I am keeping it and tge Inverter, I need a charger. I just looked at them at Walmart and found them to be expensive. So I'm wanting your opinion. On these two, I'm thinking the 20amp one. My usage of the battery will be just occasionally, like when I go camping. I'd be running some lights and other low voltage items. Plus, I may use it to charge an electric scooter. So for light usage, is this the one you would recommend? By the way, my Inverter is 1500w.
Go with the 20A. It also has the zero voltage charging feature so if your battery gets fully discharged, you can still charge it. Hope this helps. Thanks for the comment.
I want to hook up a 12v 100ah lithium battery to a 2000-watt, pure sign wave inverter to run my pellet stove for power outages. And i want use my champion generator to charge the battery. Will the 20amp charger keep the battery charged with a 6 amp draw while the stove is running ?
@OffGridBasement the 20 amp charger should have no trouble keeping the battery charged while there's 6amps being drawn from the battery though the inverter
why would you go with 25 amp when the advise they give about lifepo4 batteries they recommend 10amp to avoid heating up the battery when charging fast mode? i guess it depends of the battery ah size?
The 25 amp charger doesn't have a trickle charge after it shuts off. When it charges my 24v lithium, the battery voltage settles down to 24.60v. But when I disconnect it from the battery, the voltage goes up to 24.64v, indicating that it's draining the battery at the rate of a few watts!
That's not good. The documentation states it trickle charges to keep the battery healthy. Is that only for SLA batteries? I need to read up on it. Thanks for the info.
@@OffGridBasement Try it out but a few watts is just a guess based on a rise in voltage after disconnection. But I believe you have a better guess that trickle apples only to lead acid (and lifepo4). Also, products from Amazon are very rarely as advertised.
I noticed it's a bit better than I originally thought. It cycles on every few minutes after charging and adds a trickle charge until the BMS trips. Then it goes immediately to a slight load, I guess to reset the BMS, then started the process over again. So overall it's fine, also, on Amazon the P25 was 25% cheaper than the P20. So, bang for the buck, the P25 is better, IMO.
I have 2- 12v 100ah LiFePO4 for a 24V system. Can I use this across the two batteries (24v)? Or, should I undo the two batteries and charge each 12v seperately? Thanks for helping to teach old dogs new tricks!
You can do either method. If you need to balance the batteries so they are the same voltage then do them separately. If they are the same voltage then you just charge them as a 24v battery. Hope this helps!
I do like some of the new features that Hasito has introduced. But I am a little hesitant to purchase this unit with some of the features that they have over looked. The grips may be your biggest concern, but for me, I see the 30% labelling should be changed to something more realistic, like maybe 10%, 50%, and the last at 100%. There is no shame at charging at 2amps, and sometimes that is what I prefer. As for it not hitting 25 amps, since you didn't discharge the battery completely and start at a minimum SOC, we really won't know if this charger will actually start out at 25 amps and ramp down the closer it gets to full. Also, this unit may be auto detecting the chemistry, but I would still like to see some indication that the charger actually recognizing my Lead acid vs LiFePo, The voltage indication on the display is nice, but there are a lot of people that will be looking for some type of idiot light or indicator. Adding a simple light or an indicator on the display that says "LiFePo" would solve that solution quickly and reassure people that the charger is working correctly. Thanks for the review, always like to see new products hitting the market.
At the moment I'm completely discharging that same Lifepo4 battery in another discharge test. I'm going to use the charger to see if I do get 25amps. If so, I'll make sure to pin a comment with my findings. Thanks for the comment!
These chargers don't seem to actually terminate charging on LiFePO4 properly, they just go full blast on whatever they're set and then they abruptly turn off. They NEVER run the modes described in the manual, not sure if those are for other chemistries but these chargers definitely don't do a good job topping off a LiFePO4 battery properly.
Someone needs to do one the only specific to the cold cranking amps & not the volts, i can use any charger to get the volts up. But what about recharging the CCA amps whn they get low & want rise back up even tho the the battery is still showing 12 volt
Interesting I am still waiting for the original 10 Amp charger to fully charge the battery... The one that I did the Haisito 20 Amps charger with is finish and done. Yet... The other one is still going and both of them was at 13 volts when I started I think it was. As the original RoyPow C146 Charger have zero data beside a red and green dot, who knows how far it is.
@@OffGridBasement I actually got a similar if not the same model today. When my battery was drained or close to it where the BMS wouldn’t let it get below a certain amount I was charging at almost 23 amps. As it started to fill the charging slowed to just below 20. Still charging now but I’m guessing it will slow over time.
@@OffGridBasement I think it is ok. The max power of the charger is 240W. Most probably it can charge with 20A a 12v battery, and for a 24v battery it is half of the amps: 10A.
@@OffGridBasement Well I have 15 Amps at least on the 20Amp Charger... But I'm thinking I can charge 2 batteries at one time and maybe reach the 20 Amps. Not sure if that is possible.
Two suggestion for Hasito. Perhaps the charger was not operating at the 25amp full capacity as one of the safety systems limited the charging rate? If so, then there should be some identification that this is occurring on the charger. As some have commented earlier, it should identify what type of battery it has identified as being charged. The idea of automation is nice, but you need to know what the charger is actually doing.
Thanks for reviews, did You have a review of Haisito 20 amp charger aswell? I remember seeing it but cant find 😂 not sure if I was dreaming or remember wrong. Did the 20amp charger also pick automatically battery type, leadacid or lifepo4 or You need to press mode to pick right?
Here is the link to the Haisito 20a charger. ruclips.net/video/mtm2lNNPSSw/видео.html It's not fully automatic, but I really like it because it can wake up a sleeping BMS. Thanks for the comment.
Hmmm, to be honest, I don't see that those cables are really rated for 25A. No doubt the Chinese have skimped on the wire gauge, possible using aluminium and not copper, all of which would result in a voltage drop from the unit to the croc connectors. If this is the case, the wires will get hot.
I do notice the connection to the clamps is where it does get hot. I should make a new wiring setup to see if it makes a difference. Thanks for the comment.
Thanks for the info and the comment. I noticed my 20A Hasito doesn't get up to 20A as well. I have noticed it can get up to 10A when charging a 24v system. Very Strange.
It really is you get what you pay for if those things are not made in a reperable place that you know of it is Touch and Go whether or not you get what they actually tell you you'll get I've bought so many things off Amazon that came from overseas and tons of it not do anywhere near what it says it'll do
Got the Haisito battery charger 20 Amps, and tried it out with my new battery as well. 15 Amps max for now... Although turned it down to 10 Amps as specified by RoyPow for the best charge. Although the battery says it can do 20 Amps continuous charge. But it might not have been fully drained, so I will try things out as it goes. I guess I can charge 2 batteries 12 volt and 24 volt with it... ? So if I put 2 batteries together in parallel it should be able to reach 20 Amps without the batteries being the issue. If a battery seem to do at least 15 Amps, then 2 Batteries should easily be able to do 30 Amps and thereby the Haisito 20 Amps should be able to push all that it can.
Yes. Having two batteries in parallel would give you plenty of charging bandwidth. If there is an issue with achieving 20 amps then the charger just can't do it. Also, if the batteries are close to full the charging rate will decrease.
@@OffGridBasement Thanks for the info, and I tend to forget so easy... Yea I was thinking it should be possible to charge 2 batteries and have more then enough charging bandwidth. In any case it does 24 volt at 10 Amps which is max when the batteries are totally empty. And seems to be correct in its set max voltages. The idea is still to have the batteries on before the powerstation, get a hybrid controller and connect it to the batteries and from them to the controller. Should work, I hope....
My problem is 24v for Trolling motor. The first batt in line has locked -out. I drained too low I guess. Battery stuck on 10.v. Won’t reset. 12v 50ah(2 in series)…Second batt in line just fine…….Tried several BMS board resets. No Help
I have 20A version. Pet hate was feature that says FULL. I rather it just said 120AH, frustrating when doing a capacity test from zero. Lol. I was going to return mine but 25 A version not yet available in UK.
@@OffGridBasement Just seen the 35A version on sale in UK...but might be cheaper to use 2x20A version instead...Still I have my solar charger built in to my POWMr can do 60A max grid or 80A max from solar. so don't really need anything just right now...Still toying with Limiters idea.. If the sub meter is close to the MAIN meter can run R485 up to 500 meter I am now told.....Has a little meter you have to wire like a TRIP switch breaker...SOYA SOURCE they do Adjustable grid tie as well SOYA SOURCE invertors.
@@OffGridBasement Soya source , Are a few videos on youtube. But I think it's illegal to wire into your main circuit in UK without certification. 🤔 Maybe need a more consumer friendly company like Bluetti to famously tackle the Grid Tie issue properly . Thanks
@@OffGridBasement Update: I have the same unit. These produce a TON of RFI noise. So if you're a ham radio operator expect the HF bands to be wiped out completely while charging your battery.
I actually like the 20A charger better for the fact that it can "wake up" a dead LiFePo4 battery because it's considered a dumb charger. Thanks for the comment!
My 20A from different vendor name never reaches past 15A from a empty battery. It gets bit hot and shows 45c perhaps that is limiting the max current. I am starting feeling a bit frustrated with false Chinese advertising crap they do.
That sucks. I've never been able to get to 25 amps with this charger. I'm just glad that it works, but there are ones out there that are better. What type of battery are you charging?
you are too picky. nothing is 100% efficient. some materials have more resistance than others for the current to flow, so the percentage is only an estimate. as long as it charges, who cares about the rest. lol
I'm always wary of companies who offer rewards for positive reviews. If they want good reviews they just need to produce a solid product at a fair price and the rest will take care of itself. Now I know they pay for five star ratings I can no longer consider purchasing this brand.
I have a problem with my P25 model. The charger cannot detect the type of battery to start charging. I Uploded the video about my problem: ruclips.net/video/7Vp2AxJE1vw/видео.html
Maybe they have some kind of bullshit calculations as we see so often with stuff - dishonest nonsense as this world loves to deceives. But I will further test this 20 Amps out and see if I can reach 20 Amps.

I would just get the 20A version. Thanks for the comment.
I have 20A version. Pet hate was feature that says FULL. I rather it just said 120AH, frustrating when doing a capacity test from zero. Lol. I was going to return mine but 25 A version not yet available in UK.
The 25amp isn't working the way it should. I would wait or go with something else.
@@OffGridBasement Just seen the 35A version on sale in UK...but might be cheaper to use 2x20A version instead...Still I have my solar charger built in to my POWMr can do 60A max grid or 80A max from solar. so don't really need anything just right now...Still toying with Limiters idea.. If the sub meter is close to the MAIN meter can run R485 up to 500 meter I am now told.....Has a little meter you have to wire like a TRIP switch breaker...SOYA SOURCE they do Adjustable grid tie as well SOYA SOURCE invertors.
@@SolarResurrection Thanks for the info. I've never heard of that company. Using the charger in powMr would probably be more efficient.
@@OffGridBasement Soya source , Are a few videos on youtube. But I think it's illegal to wire into your main circuit in UK without certification. 🤔 Maybe need a more consumer friendly company like Bluetti to famously tackle the Grid Tie issue properly . Thanks
Actually I would agree - why does it just say full when done - I wanna know how many Ah has been charged. That actually sucks so much.
Great review, thanks for posting!
Seems like this charger is a step in the wrong direction.
It is in my opinion. They need to keep the option of waking up a BMS on a lifepo4 battery. Thanks for the comment.
The charger will ramp DOWN the current/voltage as the battery nears full charge. That's normal.
Thanks for the info and the comment.
@@OffGridBasement Update: I have the same unit. These produce a TON of RFI noise. So if you're a ham radio operator expect the HF bands to be wiped out completely while charging your battery.
just got this one, in post now, only £5 more then the 20a one, :)
I actually like the 20A charger better for the fact that it can "wake up" a dead LiFePo4 battery because it's considered a dumb charger. Thanks for the comment!
@OffGridBasement going to get the 20a, as the 25a will not wake up sleeping lifepo4, will not go over 29a, that's the 25a one
My 20A from different vendor name never reaches past 15A from a empty battery. It gets bit hot and shows 45c perhaps that is limiting the max current. I am starting feeling a bit frustrated with false Chinese advertising crap they do.
That sucks. I've never been able to get to 25 amps with this charger. I'm just glad that it works, but there are ones out there that are better. What type of battery are you charging?
@@OffGridBasement 100ah Lifepo4 timeusb pro
I just got the same charger it's D.O.A I plug it in and get nothing.
That's a bummer.
Do you have to be somewhere or are you giving a review . . . .
Did the review of the battery charger feel rushed? Is there something specific you wanted to know?
you are too picky. nothing is 100% efficient. some materials have more resistance than others for the current to flow, so the percentage is only an estimate. as long as it charges, who cares about the rest. lol
You're right. Being able to charge at a decent rate is all that really matters. Thanks for the comment!
I disagree. I could buy the 20 amp version cheaper if it’s not actually giving you 25 amps.
I'm always wary of companies who offer rewards for positive reviews. If they want good reviews they just need to produce a solid product at a fair price and the rest will take care of itself. Now I know they pay for five star ratings I can no longer consider purchasing this brand.
Thanks for the info and the comment.
I have a problem with my P25 model. The charger cannot detect the type of battery to start charging.
I Uploded the video about my problem:
ruclips.net/video/7Vp2AxJE1vw/видео.html
That is interesting. That's a SLA battery, correct? I can send an email to Hasito, but I don't know if they can help since the charger is HTRC.
Maybe they have some kind of bullshit calculations as we see so often with stuff - dishonest nonsense as this world loves to deceives. But I will further test this 20 Amps out and see if I can reach 20 Amps.
It might be one of those "in perfect test conditions" type of deal. Real world is probably way different.
sweet video thanks for sharing also ill go back and watch some of your older videos kk brother i hope that helps you out somehow
Thanks!
LOL YEAH I SEEN YOU IN THE LI TIME BATTERY COMERCHIAL SO COOL AND NO I CANT SPELL FOR SHIT LOL
Hahaha! No problem. I saw the commercial as well. I'm pretty happy about that!
send me one of these bad boyys lol
