The 24 volt lithium battery charger is designed to maximize the life of batteries. A multi-stage charge profile and protections are implemented to reduce stress on the battery.
Charge status indicator of the 24V li ion battery charger
Red | ● Charging or disconnect form the batteries |
Green | ● Batteries fully charged |
Red flash | ● Reverse connection with the battery ● Faulty battery ● Short circuit |
When charger is disconnected from the mains, or battery is fully charged, a relay is used to disconnect the charger from the batteries automatically, to prevent the battery from flowing back (Backfeed).
Effective natural cooling thermal management enhances operating performance and reliability. U-shaped heat sinks which fit perfectly with the housing, dissipate heat in an effective way to ensure the charger with long life span.
The 24V 7S 18650 lithium ion battery charger operates safely and silently. With the application of soft start technology, the output is spark free.
