Cloudenergy 12V 100Ah LiFePO4 Battery Pack, 1280Wh Energy, 6000+ Cycles, Built-in 100A BMS, Support Series/Parallel, for Backup Power, RV, Boats, Solar, Trolling Motor, Off-Grid

Q1: When I get the battery for the first time, does the battery need to be charged?

A: There is only 50% charged when you get the battery. You need to fully charge the battery.

Q2: How to charge the battery?

A:

Scheme 1: You can use a lithium iron phosphate 4-string (14.6V) charger to charge the battery pack.

Scheme 2: You can use photovoltaic solar panels to charge the battery through MPPT. 

Scheme 3: You can use the inverter to charge the battery pack (note: the inverter needs a built-in AC to DC charging function).

Q3: How do I connect the lifepo4 battery in series or in parallel?

A:

1. Please use 14.2-14.6V charging voltage to fully charge all lifepo4 batteries individually;

2. Connect your batteries one by one in parallel, and leave them together for 12-24 hrs to automatically balance the voltages of two adjacent batteries. And then, you can connect your batteries in a series or/and in parallel.

Note: The voltage must be consistent, allowing a difference within 100 mV.

Q4: How to activate the battery when BMS cuts it off for protection?

A: If the BMS has cut off the battery for protection, you need to cut off the load of the battery and put the battery aside for 30 minutes. Then the battery will automatically recover itself to normal voltage and can be used after fully charged.
