Charging Lipo Batteries using a Parallel Board

- Tutorial for beginners on how to use a parallel charger. It requires some simple math but nothing you can't handle. It's easy. Let's get started.
Bonus clip discusses the use of a charge board that allows you to charge multiple 1S batteries no matter what the Mah rating or voltage.
CORRECTIONS:
I accidentally said that the LiPo's shouldn't be more than 0.4v apart when charging 4 on a parallel board. I meant to say 0.04v.
I misspoke in the video. For operating the charge board to charge a 2S battery, only the balance lead is used. Do NOT plug the small white JST PH2.0 power lead from a 2S battery into the 1S port! The 4 ports on the charge board are for 4 different batteries, (2) 1S and (2) 2S. Do not mix the two together!
OTHER RELEVANT VIDEOS:
If you have a 4-button hobby charger similar to this one, they all pretty much have the same interface. Charging Li-Po and Li-Ion isn't that intuitive b/c of the way the interface is set up. If you need to know how to switch from one to the other, this is how: • How to Operate your RC...

This is the only video that helped me. All the other people like Jb and mr Steele didn’t not explain it well like you did
Thanks! Yeah, I found that a lot of the videos out there assume that the viewer knows a bunch of stuff already. But if they did, they wouldn't be watching the video! Haha. I try to make it as user friendly as possible. We all had to start somewhere and there's no shame in being a beginner. Just trying to lay out all the stuff I had to learn to so that others can understand it also. No need to speak in jargon to sound all fancy. Regular language for regular people. I'm very happy to hear this was useful for you.
You sir have finally done it, explained this is a way that can be understood by anyone. JB's, Mr. Steel's and others videos have not helped me find the answer of adding up the sums of all batteries. for 3 years now I've been raising my amps but not my mAh so my batteries have been running out much sooner. I knew it was my charging but every time I researched it no one clearly said add mAh, just amps. I can change ether on my charger so it was confusing.
Thanks! Yeah, I also found that a lot of other videos are hard to understand b/c they assume you know all the jargon and all that. Figured I'd start people from scratch.
When selecting batteries, take into consideration the weight. You have to find the right balance. You can have a lighter weight battery with less mah and actually get substantially more flight time. Why? Because mah carries its own weight and needs to lift it's own weight before you'd see any reflection in additional flight time. Same with EV's. Everyone thinks they want the largest battery for the biggest range, but the larger the battery, the exponentially less efficient it becomes.
Excellent 👌
Nice thanks 😊
Sure! Glad to help.
Parallel charging always seems like a dangerous proposition. Great video well explained thanks for sharing. Still using the supplied charger over here.
I know what you mean. I still charge at 1C rates even though I "know" that 1.5C - 2C is doable. Parallel charging is also good for setting batteries to storage charge. Less dangerous that way too b/c batteries won't ever be overcharged since they're only hitting roughly 50% by design.
Hello. How does the charger know when each battery is full? What if one charges faster than the others?
This is the closest video I can find. I have the second charger you show here along with identical batteries, both EMAX and crazepony. Are they both the same voltage (for the switch setting?) Also when plugged into a USB all I get is green flashing LEDs, not solid? I can't find any information on the net or in the instructions...
I have never seen the flashing LED lights on the charge board. It should be a very bright solid green. If it’s not plugged into the USB snuggly, it will have a very faint flashing green. As for parallel charging batteries of the same spec, I would only do it if they were the same manufacture because the C rating may be different. She ratings are known in the industry to be in accurate so you never really know for certain. If you’re talking about the charge board, each connector is completely independent of the others. You are safe to mix and match different brand and spec batteries for the charge board. Not true of a parallel charging board. Only the USB one I showed in the video. I have a different video about field charging using that USB charge board that might be relevant for you too.
I have 1s batteries with xt30 connectors. Will this work on a parallel board? Will it work even if I don’t have anything plugged in the balance ports? Regardless, I’m still finding this vid very helpful! Thanks!
No, it will not work w/o anything plugged into the balance ports. The parallel boards require it and most chargers will not allow you to charge w/o a balance lead plugged in.
Your best bet is to get a charger that's specific for whoops. There's a few out there with multiple ports. Multi-channel so it's not parallel charging, meaning you can charge 4 or so all at the same time with different voltages by different manufacturers and different mah capacities. They run about $30-40 last time I checked.
Is it OK to storage charge multiple lipo packs, using a parallel board following the same rules for parallel balance charging and simply selecting "storage mode" on the charger ??? Essentially, can I parallel storage charge multiple 2S 700Mah packs via a para board ?
Thanks, your videos are great
Yes! That's actually safer. If you're charging up to storage charge (e.g. 3.70v to 3.80v) that'll be easier than discharging to storage charge (3.90v to 3.80v).
Most chargers don't discharge at very high rates. You can set your discharge rate for your 700mah pack at 0.7amps and it will probably discharge at 0.3amps or less.
Most people don't talk about discharge rates for chargers, but the limits are generally very very low.
I use an ISDT FD-100 which can discharge at high rates. The C rating is the discharge rate. So technically, you can discharge your 700mah pack at 6amps w/o it being dangerous. I would recommend 3amps though.
@@Funcentric Thanks for the quick reply....someone should do a video, (Hint Hint) 🤣😂 And thanks for your informative content . Keep it coming
@@tonyc7049 Haha, yeah it's something people slowly figure out on their own but it's quite a disappointment when you do find that the discharge rate is soooo much slower than the charge rate. I may make a video about the discharger I use. The value isn't as good. Used to be $27. I was going to get a second one, but I think it's now closer to $40 after shipping.
What’s the point if you have to check them all before, just get a 1S charger with 6 ports.
Good question. It compliments each other. Just different options. I use a charge board off a power bank in the field or when my charger is busy charging other batteries.
1. Most 1S chargers only allow you to choose between two amperages.
2. Some people may already have a charger and would rather spend a few dollars on a parallel board or series connector instead of spending more on a full on charger which would also require a power supply.
I see you selected "lipo charge" with the parallel charging. Can you select "balance charge"? Or does it have to be regular charge when doing parallel?
You can, but it won’t really make a difference since it’s essentially thinking it’s still a one cell battery. The different ports on the parallel board aren’t recognized as “cells” when charging parallel.
This is completely different from charging serially, in which case you would definitely use the balance function.
What if i have 3 200mah lipos and 1 150 mah lipo? All 1s
You can’t charge batteries of different specs together. 3 200mah in parallèl you add the mah so it becomes a 1S 600mah battery to charge at 0.60amps. The 150mah you have to charge separately.
For 1S batteries though, I recommend charging in series. Add voltage but mah is the same. So 3S 200mah at 0.20amps. You need a series connector with three wires though. You have to fill all three ports.
@@Funcentric ahh gotcha i just bought this protek parallel board thats why i was askin
@@jonathanurdaneta5305 I see. In that case, just charge them by adding the mah. All voltage has to be the same. So don't charge ones that are at different voltages. You'll need to plug one at a time so you can check first.
Ive got the happymodle mobula 7 parallel charger. I only have 3 batteirs and it requires 4 at all times. Is there any way of making a dummy battery for the fourth slot?
Not that I know of. Curious what charger looks like that you're referring to. I have one charge board that came with my mobula 7, but it wasn't a parallel charger and it had 6 ports. Looks like they changed what they supply these days.
It's a series charger not a parallel charger. Move the yellow thingy in the middle to the 3 slot to charge 3 batteries.
Thanks. All my questions finally answered :-) I'm a new owner of Tiny Hawk II. And one question, is any reason that I should charge lower current than nominal battery? For example for 1800mAh charging by 0.4A? Is better for battery?
Awesome! Glad I could help! Sorry to hear about the Tinyhawk II though. Don't worry, you're not the only one who fell for all the great reviews on that thing not realizing it was for short term ownership. Enjoy it while it works. It's great and you'll want to fly it everyday, but when the flight controller dies on you 3 months in and you're wondering if you should really spend $60 on a new flight controller, wait for ship times and question your soldering skills, you'll probably say no and look for a new quad. I'll see you in the Facebook Groups for Newbeedrone then.
If you want a method for charging 1S batteries on the go, I have another RUclips video that'll help you with that.
Back to your question: Yes, it's just a rule that running fewer amps to the battery improves longevity. Think of a coach pushing to to run. You have a max and you'll get exhausted if pushed too hard. If you go at your own pace, you'll last longer.
Lately, I've been charging my 1500mah batteries at 1.2-1.3 amps. Only when I'm in a hurry do I do the full 1C at 1.5 amps. For smaller batteries, it's less important only b/c smaller batteries are usually cheaper and are more disposable. I still stick with the 1C rule though of mah rating / 1000 for how many amps to charge it at or slightly under.
@@Funcentric Thanks, regarding Tiny Hawk, my plan was to fly in simulator for some time, what I already did, and then switch to Tiny whoop - TH2 seems to be the best solution, in future I plan to swith to some 3' quad. Maybe using only 1s is safer in my quad?
@@flyhigh1491 TH2 has a poor history of reliability so just expect that after a short period, it may stop working. a 3" quad will run substantially stronger. You may be surprised by the power of a 4S 3" quad. I would still recommend something by Newbeedrone after your TH2 goes kaput.
Nice video. What options you have if you have 4 batteries and 2 of them don't have the same voltage?
A. Bring them both to the same charge, then parallel charge. Like if one is at 3.6v and the other is 3.7, bring them both to 3.9v individually one at a time. Then parallel charge them both together to full capacity of 4.2v. B. You can check out my other video about the best way to charge in the field using a charge board that doesn’t care about equal voltage of each battery.
@@Funcentric that you mate! Yes ill have a look :)
@@kelapse8587 No problem. Let me know if you have other questions. Happy to help.
@@Funcentric Thank you! :) Well i just bought a Mobula 7 drone and i want to find out what is the best way to charge 1s batteries. not sure whats "better" parallel or in series. many information online and if you are new it is sooo confusing. whats your opinion? :)
@@kelapse8587 series allows you to charge batteries that are different voltages but it still needs to be close. And all ports need to have a battery in it. So if you have a cable in series and it has 6 plugs, you must plug in all 6 batteries which I find even less convenient. You can’t just charge 4. You have to wait until you have all 6.
I say parallel is much easier than series. Charge as many as the parallel board can handle but voltage needs to be exactly the same or off by 0.01v at the most.
For 1S batteries, use my external battery pack method with charging board. Or plug the charging board into a sub adapter into your wall at home if not on the go. Voltage do not have to match at all. It can be way off from others because it’s charging them individually. Have you watched the video yet?
hi, friend, parallel charge board is not good option now. i bought a 1s lipo series charging board for 6 batteries as one pack from HobbyFly brand of Amazon.that is the new charge and storage solution for 1s lipo battery.
Sorry, but I'm not quite understanding what you're saying.
Can u explain why this parellel charger is no good?
@@verofpv6152 I’m mot sure what John Wilson is talking about either. Parallel charging and series charging are different and both have their place. There are reasons to do one vs the other depending on the scenario.
Both should have voltages around the same as the others. With parallel changing, it’s more critical for safety for series charging, the downside is that it’s slow if not all packs are close in voltages.
If wattage and amperage is limited on the charger, then series charging won’t help. You’d want to do it parallel where you can keep the amperage down.
@@verofpv6152 the parallel board has battery voltage deviation limited. it should be not bigger than 0.1v between batteries actually. and the bad battery will do harm to the good one. for example, the bad battery is zero voltage. it will.make short circuit during the parallel board. the battery will fire at the worst situation.that is my opinion.
Good video but if you could stop smacking your lips every time you talk it would be far more enjoyable LOL
If the batteries are high voltage do you still charge same way. So I have 4 450mah HV batteries would I put in 1.8amp?
Yes, at 1.8amp, but your setting will need to be for LIHV to charge to the full 4.35v per cell. If you use the LiPo setting, it will only charge to 4.2v per cell which is fine but you just won't get as much juice out of it. Not all of these 4-button chargers have the LiHV setting unfortunately. This particular one does.
@@Funcentric thanks for your help
@@sheapyfpv8224 Sure thing. If you don’t have a LiHv charger, make sure you check before you buy because not all of them offer that feature to charge that battery chemistry.
If you have a Single HV USB charging cable you can top up the individual batteries after they have been charged on the parallel board. This maximises the voltage/flight duration and minimises charging time.
Stop smacking your lips between sentences. Very annoying.
Lol. I hate myself for that too. So annoying.
hah I thought the same thing. still a good video though
@@Island_Line_Rail_Productions Haha, thanks. Still working on the annoying sounds. Haha.
@@Funcentric no need to worry about your subconscious habit. It's just how your body works & no need to change it for others. It should never be an issue at all because newbie like me watch your video for the knowledge you have. Keep it up!
@@adammasri Thanks man. I do these videos for my own record but I understand others watch it too and realize it is kind of annoying. I hate even watching it back myself. Haha.
It should be charge half of total mah 1.3mah
