The battery charger li-ion 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 21V 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 battery charger is disconnected from the mains, or battery is fully charged, a relay is used to automatically disconnect the charger from the batteries, to prevent the battery from flowing back (Backfeed).
The 24 volt smart battery charger works silently and safely. With the application of soft start technology, the output is spark free.
