I’m currently building a 72v 45ah 21s pack for an Escooter project using Lg Chem pouch cells (sub modules) harvested from a Chevy volt EV with a nominal voltage of 3.75v
My BMS which is a Batmon BMU 12s system from Ev power Australia requires a supply voltage between 9v - 30v
To obtain a suitable supply voltage within this range Am I right in thinking I can wire a 7s 3p configuration from the 21s pack to give me a 26.25v supply while spreading the BMS load across all cells in the pack.
Is there something I’m missing?
The Batmon system is modular comprising of the BMU + 2 x 12s balancers boards and a configurator. Essentially the balancing system will be wired with a 10s & 11s stack controlled by the BMU. Charge and discharge load is controlled by the BMU via a Gigavac 400A contactor .
This is my first Battery build so any guidance welcomed and appreciated.
