Product Highlights
- 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.
- 30ah lithium charger input: 100-240vac 2.0a 50/60hz output: 14.6v 30a
- Lithium chargers are based on a cv/cc (constant voltage/constant current) charge algorithm. the charger limits the amount 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 ot...
