I have a 12s4p battery that had what looks like a power switch from DIY. After about 10 on/off while setting up the board it would no longer turn off. I replaced it with a vedder anti spark and after more testing and setup (never used while riding) it has failed after about 20 on/off.
Why are these switches failing and what am I doing wrong. Neither was used under riding circumstances just assembly on my bench.
Any help would be greatly appreciated.
