Unboxing 72V 15AH and 48V 10Ah Lifepo4 batteries from BMS battery

Unboxing two batteries from BMS battery for my ebikes:

48V 10Ah LiFePO4 Battery 16pcs 38120 Cells ebike battery pack with 15-30A BMS.

72V15Ah LiFePO4 Battery 24pcs 40152 headway Cells in series ebike battery pack with 50-100A BMS. I requested a larger Anderson connector with lower AWG for free.

Lifepo4 is the safest battery chemistry as of now.
