No. GreenOE LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

Yes, you can charge LiFePO4 lithium batteries with solar panels.

It is recommended to store GreenOE LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, recharge the batteries at least every 3 months. Recommended storage environment: 10℃～35℃ (50℉～95℉), 45%RH～75％RH

Yes, our batteries support series (up to 4 in series for 48V systems) and parallel connections. Please follow our user guide for proper wiring and safety precautions.

The maximum number of connecting GreenOE LiFePO4 lithium batteries in series or parallel is 4 (4S or 4P).

Check if the battery is firmly connected.
Check if the positive and negative terminals of the battery are connected correctly.
Check if the battery voltage is more than 12V, if it is less than 12V, please charge the battery first.
Check if the load voltage matches the battery.
Check whether the load current is more than 100A, make sure it is less than 100A.
Make sure the discharge temperature is -4℉~+140℉.

Check that the battery is securely connected.
Check whether the positive and negative terminals of the battery are correctly connected.
Check whether the charging voltage matches with the battery and whether the charging parameters are set correctly. P.S. Use an adapter with a voltage of 14.6V±0.2V.
Check if the charging current is greater than 100A, make sure it is less than 100A.
Check if the battery voltage is lower than 9V, if it is lower than 9V, please use a charger with 0V charging function to charge. 6. make sure the charging ambient temperature is 0.5V and the charging temperature is 0.5V.
Make sure the charging ambient temperature is 32℉ ~ +131℉. 7.
After the battery over-discharge protection, disconnect the load and wait until the battery voltage is restored before charging, or use a charger with 0V charging function to charge.
