Troubleshooting and Cold Weather

When a lithium bank misbehaves, the cause is usually one of a handful of things, and cold weather is near the top of the list. This section is your fix-it desk. We walk through why a battery will not charge, why the BMS shut it off, why capacity seems to be dropping, and how to chase down voltage drop and bad monitor readings. Cold gets its own focus because LiFePO4 refuses to charge below freezing, so we cover low-temperature cutoff, self-heating batteries, winter storage and field tips that actually work. Every guide gives you the likely causes in order, a way to confirm each one, and the correction. Come here when something is wrong and you want the shortest path to working power again.
