Hello everyone,
this is my first post here, I am coming from https://community.openppg.com/ because I would like to build a battery pack with 18650 cells for that flying machine
Since this forum is a bit more active around battery building, I thought I'd post here.
The four motors of the OpenPPG will draw 300A peak altogether, so I need a battery pack AND a BMS that can handle this rather high (peak) discharge current.
The LG 18650 HG2 Cell has a constant discharge rate of 20A, so for 48Volts a 13S15P Setup should give me the required 300A
I had a hard time finding a BMS at all, that could handle 300A discharge rate, but this is what I found:
https://aliexpress.com/item/Free-shipping-1pcs-smart-display-3-2V-3-7V-300A-lithium-battery-protection-board-balanced-management/32741659733.html
The seller has sold a few already, and the product has 9 positive and zero negative ratings.
The BMS can handle variable 6S to 14S setups up to 300A constant discharge. It has a display and bluetooth connectivity together with an App.
Sounds all good to me.
Any thoughts from the experts here ?
