FAQ:

No power on

1. Ensure that the last "B +" line has been connected to the battery total positive pole.

2. Charge activation, make sure the charger voltage is more than 4V above the battery

pack voltage to activate.

3. Check whether the charger has voltage output.

voltage inaccuracy

Measure the actual total voltage of the battery pack with a multimeter, and fill in the actual

total voltage into the "Voltage Calibration" in the parameter setting page.

The current is not allowed

1. BMS B- and P- are two 7AWG wires, both need to be connected in parallel, otherwise it will

lead to current error.

2. Use a clamp meter to measure the actual current of the battery pack, fill in the actual current into

the parameter setting page "current calibration" inside; the larger the actual current, the higher

the calibration accuracy.

Capacity is not allowed

The first step, first set the battery capacity, the battery was how much, set how much capacity can

be set slightly larger, for example, the battery capacity of 100AH, can be set to 120AH or 150AH.

The second step, through the electric instrument to the battery discharge, the battery discharge,

put the protection board prompts the single under voltage protection.

The third step is to charge the battery, don't interrupt when charging, and keep charging until the

BMS prompts the single-unit over-voltage protection.

After doing the above steps, the capacity will be automatically updated, APP battery capacity

shown is the actual capacity of the battery, this time the SOC is also accurate, all the capacity-

related are accurate.

The number of designed strings does not match the actual number of strings

1. Check the parameter settings inside the "number of single unit" is set correctly.

2. If there is no voltage in the middle of a 2S or more strings, check whether the collection line is off.
