GENERAL INFORMATION

BATTERY-PACK MAIN PARAMETERS

The maximum continuous current that the battery can withstand.
The maximum continuous output power that the battery can support.

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 loaded 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 batteries from different brands have their special BMS)
purchased in near time (within one month).

LIMITATION FOR SERIES/PARALLEL CONNECTION
Support connecting up to 4 identical batteries for up to 48V (51.2V) 410Ah battery system (when in series)/ 12V (12.8V) 1640Ah battery system (when in parallel).

WHAT TO DO WHEN THE BATTERY STOP WORKING?
It has an 85% chance that BMS has shut it off for protection, and you could try one of the below ways to activate the battery.

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

If the battery is unable to recover itself after the above steps, please try activating by ONE OF BELOW TWO METHODS. After activated (voltage > 10V) and fully charged by the normal charging method, it can be used normally.
