No. First of all, we need to understand the importance of the battery working voltage range, lead-acid batteries are fully charged at rest between 12.6V and 12.7V, while for lithium batteries (lithium iron phosphate batteries) the voltage is between 13.3V and 13.4V, and lead-acid batteries and lithium iron phosphate batteries have different working voltages. The voltage of lithium iron phosphate battery with 20% battery capacity is about 13V, and the voltage of lead-acid battery with the same capacity is about 11.8V, so the voltage range of lithium iron phosphate battery is very narrow, and the floating range of the voltage is less than 0.5V in the case of more than 80% of the battery capacity. the specific reasons are as follows:
1. Lithium iron phosphate battery charger is a voltage limiting device, similar to the traditional lead-acid batteries, but the difference is that the lithium iron phosphate battery voltage is higher, the voltage difference is more stringent, and there is no trickle and float state during charging.
2. Many lead-acid battery chargers have desulfurization and equalization stages, which can pulse high voltage from 15.3V to 15.8V into the battery, which can avoid the electrolyte of lead-acid batteries from splitting and ensure the voltage of the battery to be equalized, but this is not applicable to Li-Iron Phosphate batteries, if over-voltage charging is performed on Li-Iron Phosphate batteries, it will seriously shorten the service life of the batteries or irreversibly damage the batteries. When the equalization mode is activated during the charging process, the BMS (Battery Management System) of the lithium iron phosphate battery will enter the battery protection mode, and the charging state of the battery will be constantly disconnected, charging, disconnected, the battery can not be charged, and may also be the battery is always in the over-voltage protection state.
Conclusion:
We can not use lead-acid battery chargers to charge lithium iron phosphate batteries, the use of lithium iron phosphate battery chargers can maximize the protection of the battery to extend the service life of the battery. If you use a lead-acid battery charger will damage the lithium iron phosphate battery.
