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
capable to charge 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 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 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 in most time. But if
there is a defect on the battery BMS, the battery will be damaged.
Troubleshooting
- If you found the battery can not be fully charged to its full voltage rating(14.6V/29V/58V), the charge tools may not compatible with it, you could check if the charger/controller contains the proper output voltage for 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 glove and some tools, you could open the top cap of the battery, take out the BMS board, and directly connect the cells wire to the terminals, then try to charge it without BMS, it’ll be safe if you have a charger/controller with protections.
- If the connected batteries could not reach the rated capacity, it may because that the unbalancing charging process causes voltage difference 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, keep the charge process until it recovers. If it’s still can not be re-charged, try to remove the controller, use a solar panel or something else with voltage higher than 15V to directly boot it.
