Terrified of my solar pannels killing my batteries this spring lol DIY heated box or just go self-heating?
i’m losing my mind trying to finalize my electrical layout before heading to the rockies next month. the days are finally getting warm, but i know those desert nights are still gonna dip into the 20s.
my battery bank has to go right over the wheel well in a super cramped spot. i'm paranoid about 7am sun the van’s freezing, the battery is frozen, but my panels are gonna wake up and dump 20+ amps into the bank. rip lithium cells.
i was originally gonna build a bulky insulated box with heating pads and a thermostat relay, but man, space is so tight i don't even think i can fit the extra foam. plus, wiring up a whole separate thermostat system for a few weeks of "shoulder season" feels like a total headache.
i’ve been seeing those self-heating LFPs online (like redodo and a couple others). supposedly the bms just uses the solar juice to heat the pads first before it allows a charge. sounds like a lifesaver for small builds, but part of me wonders if it’s just a gimmick that’s gonna fail and leave me with a dead brick in the middle of nowhere.
for those of you in high-altitude spots, are you actually trusting these self-heating units or are you still building the battery coffins with foam? i really don't want to overcomplicate my wiring if i don't have to, but i also don't want to fry $400 worth of batteries.
any real-world experience with these bms heaters during a cold spring?
