how to fast charge a lifepo4 battery? | DIY Solar Power Forum
Fast charging for cars is lithium ion cobalt variety that has fire risk. Lifepo4 for solar is slow charging (5 hours) and much lower fire risk. You can shorten the charge to 3.3 hours without much degradation. 2 hours is possible (if rated fir that), but is hard on the battery, and I wouldn''t recommend higher than 80%.
