Haven't been able to track down an answer to this, but I'm sure it's come up for some folks...
Assuming cold temps, and the self-heater inside the battery is required before the battery starts charging, some of the current that passes through the shunt (counted as % charge added) would actually be used for battery heating, not battery charging. Is this the case?
If so, what's the most accurate way to know your self-heating LiFePO4 battery's state of charge?
Several of the cheaper ones don't seem to have a smart enough internal BMS to provide this info. Honestly this one thing may lead me to purchase more expensive Renogy batteries that have a blue tooth connection right at the battery, giving SOC, self heater status, etc.
Thanks!
