I’ve been researching lithium batteries and am having trouble finding anything definitive on my question. My batteries are currently in the engine room and there is really no alternative to this location. The engine room generally tops out at about 105F while underway. I’m never in colder climates so lower temperature thresholds aren’t a concern.
I’ve seen some sites/videos suggest that the LFP batteries can be discharged across a wide temperature range (clearly between 40f-105f) but elevated temperatures only become an issue when charging. If this is the case would I have good results with LFP batteries in the engine room if I ensured the batteries only charged when the engine room temperature was 90f or lower? My generator running by itself never gets the engine room temperature above 90f. The only charging source would be a 120v AC, I would ensure the alternator wasn’t connected to the LFP batteries.
All inputs appreciated, particularly anyone that currently has LFP batteries in the engine room.
