24V 3 amp battery charger
Model :IN2903000
Output :29.2V 3A
Brand :Intai
Product origin :China
Supply capacity :2000pcs/day
Warranty :3 year
The IN2903000 24V 3 amp battery charger delivers 18~29.2V regulated charging voltage for 8 cell 24V pack. The 29.2V battery charger is a fully intelligent battery charger which communicates with the LiFePO4 battery to monitor cell voltage and charge status to optimize the performance and extend the life of the battery. The 29.2V charger is equipped with protective electronics that automatically shut down the charger when cells are fully charged or in case any faulty occurs. With the BFP protection, the 24V LiFePO4 charger is capable of preventing backflow of current into the charger from the battery. The following symptoms are incurred if the red light continuously flashes:
- The battery voltage is detected too low the charging will not be commenced.
- Reverse polarity connected or short circuited.

Red | Charging or disconnect form the batteries |
Green | Batteries fully charged |
Red flash | Reverse connection with the battery Faulty battery Short circuit |
When the 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 29.2V battery charger works silently and safely. With the application of soft start technology, the output is spark free.
