I was so excited to see Will's video recommending these highly; just phenomenal that I can now get 400Ah LiFePo for what 200Ah of Battle Borns cost me 2 years ago. That said, I was surprised to see the following blurb in their specs:
Surrounded working condition temperature: Charge: 41 ~ 113°F (5 ~ 45°C); Discharge: -4 ~ 131°F (-20 ~ 55°C) (Suggested for charging: 50 ~ 104°F (10 ~ 40°C); Suggested for discharging: 14 ~ 113°F (-10 ~ 45°C) (https://www.electriccarpartscompany.com/12v-400ah-preferred-lifepo4-lithium-battery-packs)
This floored me... I understand the low temp limitations of LiFePo, but had never heard of issues with charging or discharging at temps of 104F. Cars in the sun routinely get that hot! Battle Born specs allow charging / discharging up to 135 degrees F, so I'm assuming this is a prismatic VS cylindrical issue?
I've just sent a note to ECPC to ask what kind of damage I'd be doing by routinely charging at or near the 104 degree ceiling they are suggesting, but I thought I'd post here since I haven't seen it brought up. I'm hoping this is just a typo... I was so excited to upgrade
