Finally opted for the more chanllenging split pack. One pack is 8S4P and the second one is 2S4P. This will allow me to have clerance in the openings for the LCD screen, power button and charge port.
Thanks guys, the big piece of the puzzle here is the bms. It’s a nice Esk8 intergrated solution, with the help of @onloop.
it offers plenty of standalone features. Like CC-CV charging (constant current, constant voltage), over current protection, short circuit protection, UV and OV protection, balanced charging and a individual cell bleeding circuit in case of OV.
Usb output for charging a remote and programming the vesc. Soft start button with a momentary switch and onboard 60A fuse.
This is the first working prototype, i still have a few bugs to iron out. I’ve done enough lab tests to deam it road worthy.
This place holder for VESCS and capacitors is just epic. Great work !!! What kind of on/off switch do you use ? Isn’t it the same switch that Torqueboards and Enertion had problems with in their battery packs ? . …hmmm…wait a second…is it the BMS that onloop showed in one of his videos ?
