Charging Method
Battery charger (mains power）
The most ideal way to charge a LiFePO4 battery is with a lithium iron phosphate battery charger, as it will be programmed with the appropriate voltage limits. Most lead-acid battery chargers will do the job just fine. To select a proper charger for your battery, you should choose one that is capable of charging the ECO-WORTHY battery to full, its rated output/charging voltage should match the LiFePO4 battery’s standard charge voltage, which varies in different battery types, refer to the above parameter table for detailed data.
Solar panel (DC power)
You can also use the solar panel to charge your ECO-WORTHY LiFePO4 battery, but please make sure to choose a proper controller, it should contain the LiFePO4 battery mode or Li-ion battery mode. Both the PWM controller and MPPT controller are okay. If you don’t have a controller, you can connect the battery to the solar panel directly, too. The BMS inside will protect the battery most time. But if there is a defect in the battery BMS, the battery will be damaged.
Troubleshooting
- If you find the battery can not be fully charged to its full voltage rating(14.6V/29V/58V), the charge tools may not be compatible with it, you could check if the charger/controller contains the proper output voltage for the LiFePO4 battery.
- If the charger is suitable, but the battery still can not be fully charged, it’s may due to the fault in BMS. With a glove and some tools, you could open the top cap of the battery, take out the BMS board, and directly connect the cell wire to the terminals, then try to charge it without BMS, it’ll be safe if you have a charger/controller with protection.
- If the connected batteries cannot reach the rated capacity, it may be because the unbalancing charging process causes voltage differences among those individual batteries You could disconnect them first, and try to charge them one by one, to see if each battery is in good condition.
- If the battery is over-discharged and triggers the over-discharge protection, please remove the load or inverter, and keep the charge process until it recovers. If it still can not be recharged, try to remove the controller, use a solar panel, or something else with a voltage higher than 15V to directly boot it.
