48V 10AH. Total SLA build including bike and accessories - $450. Works great since 2019, however I'm going thru rear wheel tread every 2yrs, heavy to load in my SUV, plus I'm sure the cheap chinese bearings aren't going to last much longer. Saw on Amazon LiFePO4 batteries are now under $40 each, so I bought 4 and changed out the heavy SLA's with these. LiFePO4 batteries are same 12v 10ah. Each one was delivered over 13 volts. After installing, batteries showed 4 bars out of 5 on my battery monitor. As soon as I gave it some juice, bike stopped and battery monitor showed empty. I measured each battery and each one was still over 13 volts so I'm stumped. I'm guessing the BMS on 1 or all batteries can't take the load and shuts off? I put the SLA's back and everything works.
Anyhow, is there a 12V, 24V or 48V LiFePO4 batteries under total of $250 that will work in an on and off road environment? I'd like to use four 12V in series. Thanks for any help.
