It’s only 12A, so you’d have to bypass it. Personally I am not a fan of bypassing your BMS because you lose so many safety features
For 6S, just use a balance charger. It will work much better than that thing

I am definitely not using a balance charger. what features would I be bypassing with the cheap BMS? also what BMS would you recommend
They fail or don’t work right from the start
IMO BMS should never be the cheapest part in your build

I’m seen plenty of videos saying they’re fine. how do they fail?
Bad components , bad assembly
Do you really feel comfortable protecting your vesc and battery for $15-$20 from a noname manufacturer.
Expensive ones fail too just usually not in way that’ll ruin everything, switch might die, etc

I am using an esc since it’s a cheap build so does that make a difference
Basically what he is saying: if you are willing to put your life/body in danger, go with the eBay BMS))

I’m just confused what can happen isn’t the bms just used for charging?

12A can not use for electric skateboard. will burn when loaded too much, or during sort while.
imaging when you driving fast, then suddenly lose power, and can not brake…

I see. what is that 12A for? isn’t that for discharge?
He could use it for charging only by bypassing it, but I still wouldn’t buy a 12 dollar BMS

I just wanted to use it for charging I didn’t know it could do anything else

Over charge detection voltage:
Not to mention, that thing has a over-charge detection voltage that is way too high. It potentially could charge a cell all the way up to 4.35V before cutting off
That cheap BMS could destroy your batteries. Get one from SuPower or Bestech that is rated for the current you will actually pull. Or use the hobby charger. It will work much better

Sorry, this is my first time hearing all this
what is charge detection. how much do the BMS’s from SuPower or Bestech cost?
September 29, 2017, 8:04pm
So the thing is:
You cannot use this for discharge. It WILL cut out power in the worst moment
You can use it for charge if you are willing to risk the low quality and can’t afford better
You will get what you pay for
Bottom line. I use a cheap bms only for charging my 10s. But i can’t use a hobby charger

Don’t mean to be rude, but get on that Google machine
More searchy searchy. Less posty posty
