For others to know the B3 20watt branded HOT RC works great also. It has red lettering instead of blue.
What capacity of battery you have and how long does it charge?
hello
im have made a custom battery pack using 3s 18650 (3 cell, almost 12v).
I have also made the balanced lead (white connector ) for charging with b3 charger.
when i connect the battery to the charger, the 3 leds are always red, but i have chrged that battery pack to full before.
those led where red for long time.
what is the problem i cant understand please help
I had the same type charger under a different name, which was also quite accurate. Unfortunately in a moment of inattention I tried to connect the battery balance lead upside down into the charger, while it didn't plug in because of the lugs it did allow a connection which shorted out the charger. I usually turn the power on after the balance lead is plugged in but as I said, a moment of inattention/brainlessness. The lights on the charger still worked but I think one red and two green while not charging. They would all turn red when charging but did not balance charge and created a dangerous in balance and overcharge on one cell. I was keeping a close eye on it but wanted to see what would happen after the short, (1 cell was 4.4v & still charging!) Something to be aware of as I would of hoped there would be some kind of safeguard/circuit breaker to prevent the charger from working after the short circuit.
Cheers again for great review.
oooH that's not good but thanks for sharing, cheers and glad you enjoyed the video :-)
Tigger, once again, thank you for the very well explained video on these balance chargers. We now have three 7.4v 2200mAh batteries and the standard Syma charger with output at 10v 800mAh, so it does take a good two hours plus per battery to fully charge. Long time to wait around on a calm day.
Looking at Amazon, the price for the larger, professional charger seems like a better deal. Thanks again.
Glad it helped Mark, just make sure you get Genuine Original ones, lot of fakes around for iMAX and I would assume others, pro charger is the way to go but these small ones seem to do a good job on balancing. You will love flying longer, nothing beats it ;-)
@@TiggersRCReviewsTTFN how do I discharge a lipo battery for storage with one of those chargers to 3.7v?
The more premium/ expensive battery chargers have inbuilt storage mode to 3.7/3.8V. The budget chargers, charge to 4.2V only?
But it doesn’t discharge them right? You’re supposed to discharge them when no in use?
at 02:11 thought the 610mah is the capacity of the battery not the charging rate, the battery is capable of throwing out say 10 amps but would only last a few minutes so thought it would be capable of taking 800mah or even more say 1Ah.
Well done....and very helpful to those less familiar with batteries and electrical nomenclature in general. Thanks for sharing!
Pleasure, glad it helps :-)
Nice review! Can it charge lion batteries as well? Thanks
how many hours to charge a 2s 2000mah in that balance charger?
I like your explanations.
Great information . Helped me tons just getting into quads and lipos.
man ! I'm glad that you made this video. good things to know.
Pleasure John, glad it helps :-)
I've got a similar one, but my question is: How to discharge them for longer storage with a charger like this?
You can't
I have one very similar if not the same as this and it makes a loud hissing noise when i plug in a battery. i don’t know if this is normal or dangerous. has anyone else had a similar problem?
Thank you very much for this review, I was having a issue with my BUGS 3 stock battery not charging new out of the box. I ordered this and all is good now. The charger MJX. sent me was a dud. And I already tested this with my three cell battery's and it's great. Love your channel!
Glad it is all helping and you sorted it. Thanks for supporting the channel and enjoying it, have a good weekend :-)
i have a 7.4v 400mah battery from wltoys k989. For that the i can't use this b3 charger as its output is 7.4 1500a ?
those buzzers are so handy!!
i hear them beeping when my speedboat is 200-300 m out on the water!!
i have a cheap charger aswell, but it charges just great. only downside is that it doesn't charge a 1s lipo :/
Yep buzzers are great but very loud in the house LOL Yes mine only does 2-3 cells, hey I guess always a downside, cheers
i have a 3 cell 3300 mah 35c 11.1 v lipo battery.. my second is totally discharged and shows 0v so can i charge that single cell with a B3 imax rc charger? or how should i recover the dead battery cell , i only have the B3 imax rc charger with me.
Hi there .mine when I plug in the battery 1cell and 2 blink on and off green..is my battery messed up?. Ty
Technically those cheap B3 chargers doesn't balance, it's just 3 independent chargers and it will try to charge each cell to 4.2V and stops when C/10, so you'll have the max capacity for each cell but in no way it is balanced, it will however prevent overcharging a cell compared to a simple series charger
Hi! Really nice video! I have a question. If the charger say output current: 1,6 and the battery its 1600mAh is it save?
Yes, it should be safe but it is still important to charge your batteries on an inflammable surface.
Thank you for making all these reviews: very informative and helpful for someone starting out! I have already ordered a couple of low voltage alarm beepers and was just about to get myself one of these cheap balance chargers when I noticed the 1.5A output current for 2 cells. If that's unchangeable, am I right in thinking this would be no good (dangerous!) for charging a 1300mah 2S battery for my JJRC X1? So far I've been using the basic charger that came with it, but I suspect the balance is off (I'll find out when the voltage readers arrive!) Many thanks.
just a little bit over is fine
Figuring charger time dividing that way would be accurate only if the battery was totally depleted would it not?
Great tip I have a couple of them and now I will utilize them : )
They balance really well, certainly compared to what we usually get with the quads, TTFN
thank you , helped me so much, im a budget buyer :)
Can this charge my 3s 6200mah Ec5 lipo battery?
This was very helpful. Thanks!
I have a 7.4 Volt 1000 Mah 15C battery, will it charge it correctly?
Excellent video, really helped me buy a cheap useful charger.
Tigger you have an Imax B6 charger is this the only charger you use to balance the cells when you put the battery into storage mode? Do you have other hobby chargers if so which one do you prefer to use for that job.
Hi Barry, yep I only have one pro/hobby charger and use it for storage, seems to do a good job, but I'd rather keep flying ;-)
THANK YOU,THANK YOU!!!!!! Boy, i sure am glad i contact you!!!!!! You sure do know what you are doing
I have the new TRAXXAS EZ-PEAK CHARGER. it does 2-3-4 s batt. and it tells you what is going on. I hope this well
do. Please let me know!
Thanks, Steve

Hi Steve, glad to help, don't have that charger but looks very nice. I don't know if it works like the IMAX B6 in the way you need a positive, negative and balance charge cable, if so I 'm not sure it will charge the X300 battery. If it uses balance charger cable then should be perfect ;-) Let me know how you get on, thanks, Cheers :-)
Charging time of 2s 8000 mah 30c? 2 Lights Green Full charger.?
How to charge particular 1cell in 3 cell battery with compact charger ..?
Probably a dumb question but. Will this inexpensive charger; will it charge a 2s and 3s at the same time or only one battery at a time?
Pretty sure it wont change both at once, can't see how it could manage balancing 5 cells at once, not something I would try TBH, not a dumb question IMO
Hello.
Week ago I ordered Bugs 2 B2W(red). What additional charger you advise to buy from those 3 cheaper which are exposed? With quad I think will come such one you got at Bugs 2 B2C(USB charger at 500mA). So this will be quite slow charging.
Eachine charger have written: Charging current: 800MAH-1000MAH
imaxRC B3 and B3 20W Balance Charger have written output at 1,6A.
Probably one of those 2 lasts should fit, cause Bugs 2 B2W using 1800mAh battery. Or is safer to use Eachine charger?
Thank you.
Nice choice of quad ;-) guessing you seen my video on iMax B6, if not take a look. Hobby grade charger is going to charge fast, my B6 can go to 4.0amps someone said the latest one goes to 5.0amps.
How long to charge 7.4v 2200mAh? And 11.1v 1500mAh?
Concerning the B3 charger, when you are charging a battery and it becomes fully charged; will the charger stop charging the battery? Or should the battery be disconnected immediately when all the lights turn green? Is there a hazard in not disconnecting immediately after all the lights turn green?
Charger stops charging when battery full
question - i have an odd battery that came with my remote car - it looks like its a 3cell battery with total of 9.6V - i tried to replace it with a standard 3cell battery which is 11.1v - my remote car worked fine but after maybe 5 minutes it started to produce a little bit of smoke. is there any way to reduce voltage on the 11.1v battery to match 9.6v that the car needs? This way i can still use standard 11.1v batteries?
Hi
The battery you removed is another type of battery. It's not lipo. Lipo comes in 3.7 7.4 and 11.1 and so on.
The one you removed would by nik cad 8 cell battery it gives 1.2 volts per cell
Hey sir at 7:00 where’d u purchase that voltmeter?
Comes with charger in some deal on Amazon
good informative and money saving review. thank you ! 🖒😎
Hi John, cheers :-)
What you think. Could this B3 charger also charge Li-ion batteries?
Thank you.
No, I wouldn't use it for that, clearly states LiPo batteries ;-)
If i have a 2s 1500mah... I can't charge it by 20w 1. 6A charger?
@christiancastillo I’d love to know this as well. He said never over so I would assume no, to be on the safe side, but it is only 100 difference (1500mah battery, this charger 1600ma max current output).
Can you give an estimate on how long a battery for the bugs 3 would take to charge on the B3AC charger?
Around 1-1.5 hours I would have thought
Hi Tigger,
I noticed you had a Hubsan H502E battery (7.4v 610mAh 15c) earlier in the video. I bought an H502E recently but unfortunately the USB charger packed up after the second charge (maybe I did something wrong :( ). I was wondering if the B3AC (a IMAX B3AC ) would be a suitable replacement charger as I need one quickly and have found these being sold in the UK on eBay. I'm worried about the balance charge current as it's 800mA/cell and the batteries are 610mAh. Many thanks for help.
Yep that will work and any 2 or 3 cell ones you may get in the future ;-)
Proper job mate. Many thanks for your help :) Will a Professional iMAX B3 RC be OK too?
Pleasure Andy, pretty sure the Pro one only puts out at 800mAh, not done a full side by side, may give it a go, happy safe charging
Thanks a bundle for your help :)
Can i charge with a paralel connector
Can this charge a 2000mah battery
i have the first balancer you showed, the chinese one, what happens if i interrupt the charge, like if the charges gets unplugged for a second, will it overcharge the battery? or naw/...
Nope it only chargers what the battery needs, hence you can charge them from any state, ie half charge, full discharge, storage etc ;-)
to the cheap balance charger i bought a cable which splits into 2 and you can charge 2 batteries from one balance charger.....is that good or bad? shall i charge one battery at a time or two?
I would do one at a time as far as I know it can't balance charge 2 at once how could it control it :~) If someones knows it can then great, just my understanding of how it works. Guess you could try it by monitoring every so often and see if it achieves what 4.2v per cell. One last thought it won't charge it any quicker as it only puts out 1.5amp on 2s. Hope that helps cheers
Ok thank you very much for the information
can we charge a 2s and a 3s lipo together at once with that B3AC balance charger?
No. Pretty sure it is a 2 or 3 cell charger ;-)
i actually tried and let it be for few mins and nothing exploded. i think we can. since it has 2s and 3s balance port.
Be interesting if that takes the same time, guess the power is going to the port anyway so maybe it will work, cheers for trying and sharing :-)
Is it auto stop charge when full charge done
Yes
Will it charge mjx bugs 2 battery which is 7.4v 18000mah??how long does it take?
Yes just over an hour
Hi does this charger charge 400-450 mAh 2s safely?
With the skyrc charger you can limit the current 0,1-6 amps .Just set it to 400ma I don't have that small batteries I charge my 5000mah battery's with 5 amps
Does charger like this are good for bigger lipos like 2s, 4000mah?
it'll work, just take longer to charge as charge rate for 2s is 1500mAh
Great, thanks!
Is there anything else I can purchase to charge more batteries or something else around this price thanks?
Not really for 2 or 3 cell
good, handy to know,
at 2:16 is not a correct information, you can charge a lipo like that one at more than 2a with no problems
very nice video.
Thanks :-)
Someone say that this charger will distroy you battery is it true?
I use three of them constantly, never had an issue ;-)
thx to u
But it doesn’t discharge them right? You’re supposed to discharge them when no in use?
