36v BMS + charger

Post by rupy » Mar 10 2018 7:12pm

Hi I'm looking for a kit that includes BMS and charger.

Anyone seen something like that around?

And if not how do you match the BMS with the charger?

More specifically, is it the BMS that knows when to cutoff the charging?

So then you just supply the BMS with 36v? Or does it need to be higher?

I can't find the info about what voltage the charger should be.

When I search on ebay I get 42v chargers for 36v packs is that right?

Yes for a simple answer. The charger should match the type of battery you have and the voltage. 10 cells in series at 4.2 volt equals 42 volts for a 36v battery.

But what says that 3.6v cells want 4.2v to charge?! And why?

Would f.ex. this do: https://www.ebay.com/itm/42V-2A-Charger ... 3013264877
