I'm looking for a AC fast charger for the 48V 16 kWh LiFePO4 battery I'm putting together (EVE MB31 314 Ah cells). The only things I could find are...:
The BigBattery (BB) one seems like the right one, because the EG4 seems to be marketed as for use with gas generators (NEMA L14-30P). But, at the same time the EG4 can also be used with a 220V house outlet. Furthermore, the EG4 can charge twice as fast as the BB model for essentially the same price. Also, while both charges 48V LiFePO4 batteries, the EG4 charges at 57V max instead of the normal 58.4V (like the BB model). Lastly the BB model says it's only compatible with certain BB batteries, but yet the DC connector for the battery side is a common Anderson plug.
What am I missing here? Can I still either charger with my DIY battery? Will there be any issues or gotchas using either charger??
