Thank you for confirming Goatman. I had a few used pouch cells that I wanted to put to use and 15s was the best I could do. I hope the active balancing board keeps them all somewhat together.
I hope it's understood that I put a very low value fuse in place in case things go south.
The active balance board balances anytime voltage's exceed 0.2v between cells.
The Lipo cell alarm lets me know when my cell voltages Get Low.
This is not something I recommend unless you are willing to experiment. So far I've been pleased.
Yes, Stock controller! No overcharge protection...
Just data for anybody that can use it. 10/19 purchased BBSO2 48v 750w mid Drive from em3ev.
I built a 15s battery pack from 12.5aH lithium soft pouches. No BMS and I am using an Active Balancer 1.2amp. I use Low Voltage cell monitoring to alert me when my cells get to 3.2v.
I bought a 15s...
I'm sorry I'm unable to offer any advice other than have you considered purchasing the $10 motor controller tester from banggood or Ebay. I wanted to give you a link but I was unsuccessful.
