• For Lithium Batteries Only: This charger is designed for lithium-ion batteries only. Do not use it with LiFePO4 batteries, as this can lead to excessive heat and potential damage.

• Usage Tips: Always connect the charger to the battery first before plugging it into AC power. Unplug the AC before disconnecting the battery to avoid damaging the battery.

• Temperature Consideration: The charger may get warm during operation (up to 60°C), which is normal due to the heat dissipation process.
