48V BMS 30A continuous 60A peak

Post by Nobuo » Nov 26 2014 5:31am

I've bought this BMS, (30A continuous, 60A peak).

http://www.aliexpress.com/item/13-lithi ... 21963.html

its the only one I could afford..

and I realise that my controler is 45A max continuous.

http://www.aliexpress.com/store/product ... 94528.html

I'm going to make a 48V 13s14p battery pack. that should be able to give 60A max continuous (at ~2C dischargue per cell).

How this could affect to the BMS? maybe is a stupid question, but I can't find the answer in the forum, I'm not so clever with the search bar.. :x and the seller say to me that there is no problem..

Should I limit the continuous current of the controller to 30A max?

I just wanted to share my question with You,

that is the BMS that sunthing guy uses on his bigger battery packs. it should work for you if you have a 13S liion pack.

Yes I will use that LG that have very similar specs as ncr18650PF from tumich.

But because I will put 14p. I could reach easily 60A continuous from my battery pack if my controller would let it.

Its only because, in such case, I don't understand the rating (30A continuous 60A peak) from the BMS :roll:

I will try to explain myself. :P

I have this controller. 48V rated at 45A max.

http://www.aliexpress.com/item/High-Qua ... 94528.html

I will have a 13s14p with those Lg cells or smiliar ncr18650PF that can give 10A max more or less.

and a 9c standart 1000w motor

http://www.aliexpress.com/item/High-Qua ... 13046.html

If a push throttle to the max. how much Amps I will be sending through the battery to the motor? :roll:
