Charge Status Indicator of 7.4V Lipo 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 automatically disconnect the charger from the batteries, to prevent the battery from flowing back (Backfeed).
Mechanical Specification(mm)
The battery charger for 7.4V works silently. With the application of soft start technology, the output is spark free.
