Intai offers the best battery charger that 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 Battery Pack 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).
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 18650 high quality battery charger works safely and silently. With the application of soft start technology, the output is spark free.
