HOW TO ESTIMATE THE BATTERY CAPACITY

STATE OF CHARGE (SOC

• The battery capacity could be roughly estimated by its resting voltage (not charging/discharging voltage)®.
• Since the voltage of each battery is slightly different, and the voltage measurement is affected by the measuring instrument, ambient temperature, etc., the following parameters are for reference only.
• The actual SOC of the battery is based on the discharge capacity under load.
• Resting Voltage:The voltage is measured after the battery has been disconnected from the charger and loads with zero current, and left alone for 3 hours.

• Based on the characteristics of LiFeP04 batteries, the voltage measured by all LiFeP04 batteries during charging/discharging is not the real voltage of the battery. Therefore, after charging/discharging and disconnecting the battery from the power source, the voltage of the battery will gradually drop/increase to its real voltage.

SERIES / PARALLEL CONNECTION

THE PREMISE OF CONNECTION
To connect in series or /and parallel, batteries should meet the below conditions:

• identical batteries with the same battery capacity (Ah) and BMS (A);
• from the same brand (as lithium battery from different brands has their special BMS);
• purchased in near time (within one month).

LIMITATION FOR SERIES/PARALLEL CONNECTION
Support connecting up to 8 identical batteries for up to:

• 2 in series as 48V (51.2V) battery system/
• 4 in parallel as 400Ah battery system.

WHAT TO DO WHEN THE BATTERY STOPS WORKING?

General Steps

• If the BMS has cut off the battery for protection, follow the below steps to activate it.

  • Step 1
    Cut off all the connections from the battery.

  • Step 2

  • Leave the battery aside for 30mins

  • Then the battery will automatically recover itself to normal voltage (>20V) and can be used after fully charged.

• If the battery is unable to recover itself after the above steps, please try activating by ONE OF BELOW TWO METHODS.

• After activated (voltage > 20V) and fully charged by the normal charging method, it can be used normally.

Method 1
Use a charger with lithium battery activation function to fully charge the battery.

Method 2
Connect a controller that supports 24V LiFePO4 battery charging to charge the battery for 3~10s in sunny daytime.
