Descriptions- Lithium chargers are based on a CV/CC (constant voltage/constant current) charge algorithm.- The charger limits theamount of current to a pre-set level until the battery reaches a pre-set voltage level.- The current then reduces as the battery becomes fully charged.- This system allows fast charging without the risk of over-charging and is suitable for Lithium Iron and other battery types.- Ultimately, using a battery charger with a specific Lithium charge algorithm is the best option for maximum performance and lifespan of any lithium battery.-Using any other charger may cause damage to the Lithium battery. - Specifications40A 14.6VType: Lithium-ion Battery Charger - Input: 100-240Vac 2.0A 50/60Hz - Output: 14.6V 40ASize: 20.5cm x 12.1cm x 10cm - Colour: Silver+Black - Plug: AU Plug Notice:- NEVER turn on before connect lithium battery positive and negative correctly!- NEVER short circuit between this charger's positive and negative!
