Hello EV friend,
i've built a 14S4P battery pack and would like to charge it with a bit less than 58.8V for better cycle life. As i've heard that most common chargers have potentiometers inside that allow you to lower the voltage i've bought a 58.8V/10A charger and as the company offers the same charger in many different specs i was hoping that there are potentiometers inside that can be adjusted. But as i opened it up all i found was a weird chip board with something that looks like a connection for a wire or something. So i'm pretty sure the company adjusts their chargers with this chip (NUVOTON MS51FB9AE, 136HBHA) and i was hoping anyone here knows something that gets me closer to a solution. I thought maybe its something like a arduino that can "easily" be programmed with the right program ? Has anyone seen something like that before ?
Thanks for your help
