LifePo4 Charge Performance
Thinking seriously about replacing our two GC2's with a pair of 100ah LifePo4's. Hearing a lot of chatter about how lithiums accept a charge much quicker than lead cells. Very familiar with how ou...

kinda matches the specs for the cells I posted eh.. I think the reason there is so much confusion around is people who build batteries and put the warenty on them realize that that cold charging area is a fine line and has the most capability to dammage a battery. they set the internal BMS charge cutoff at 0 and say they cant be charged under 0 degrees. and realy in our aplication this is what they should be doing. if you build your own I would recomend the same settings. unless there is areason you want to buy a constant voltage adjustable current power supply and sit there and babysit your charging.
but also remember people confuse this with ambiant tempature which it is not. it is the tempature of the battery cells themselves. so yes if the trailer has been shut down for a while and sitting outside they will proabably be the same. but discharging or charging in its self warms batteries so you can discharge for a little bit of you need to warm them slightly, but that may not be practicle. but if you build it in an interior space your golden, and this is possible as they are smaller and lighter than traditional batteries.
