Waterproof 12V 20A LifePO4 Li Ion Battery Charger

To maximum lifepo4 batteries' performance and lifespan, it's necessary to use a proper lifepo4 battery charger with a specific lithium charge algorithm.


Product Description

When charging lifepo4 batteries, normal lead acid battery chargers can be used but will never fully charge a lifepo4 battery, needing to be switched off when the battery is charged. Or problems will occur.Also some smart lead acid battery charger has the "float voltage" state, where the voltage is far below the level that its possible to charge lifepo4 battery. It is recommended to use a proper lifepo4 battery charger with specific lithium charge mode to maintain the battery lifespan and performance.
