Negative, lifepo4 especially does not like charging in sub freezing. I will disconnect the charger for the winter but will keep a watch in voltage to make sure the bms(or anything else) doesn't leech the battery dry.Cool! I hope to get my batteries ordered soon so I can catch up with you guys. This is all very exciting.
Once you have the charger stuff all figured out, do you plan to keep it plugged in through the winter?
+1 for needing a quick look at SoC while mowing, again, would also like to monitor amperage to keep my mind at ease.I just pulled the existing meter there is a six pin plug and a 4 pin opening. Only uses 3 pins. Trying to hunt down who actually makes this. Maybe the other pins are for different chemistry. I already have the bluetooth module on my BMS for accuracy. Personally, I just want a rough-ass look for SOC.
Edit: Looks like it's made by Curtis Instruments. Very similar to their 803 with the voltage curve dial missing. Doesn't look like it adjusts high enough anyway though. It does appear that it's 2" though! Maybe I'll grab the one with the shunt afterall. Do you think it maintains ah usage if power is disconnected though?
