Manual fast-charger, suitable for Power Packs with 26 V and 6 A charge current
Page 4 of 6
Functions
- This charger is suitable to charge a 25.2 up to 25.9 Volt, Li-Ion battery pack, with 7 cells in
serial. The max. charge current is 6 A max.
- The charger has an overload, short circuit, overvoltage and wrong polarity protection.
Overload protection (cut off if the output current is higher than 6.35A)
Short circuit (cut off if there is a short circuit on the DC-side)
Overvoltage protection (cut off if the output voltage is higher than 29.7V)
Wrong polarity protection (cut off if battery with wrong polarity is connected to the charge
cable)
- The charger has an internal temperature control that protects the charger at to high ambient
temperature as well as continuous overload. If this happens the charger will reduce the
output power and start turning it’s fan.
- The fan will be deactivated, if the charger will switch to the so called constant-
voltage-mode. In this case (typ. Min. 4 battery LEDs are lighting) the power output of
the charger is that low, that the fast-charger has not tob e colled by the fan.
Operation
1. Before first use please check the parameters of the charger and your battery according the
rating label or the provided documentation to ensure the accordance.
2. Check if that the local main AC voltage level is suitable for the charger.
InputVoltage: AC 110-240V, 50-60Hz
InputCurrent: max. 3 A
3. Plug in the mains cable into an AC mains socket.
4. Turn ON the charger and wait until the green LED is flashing slowly.
5. Now connect the DC cable to the battery pack. The green LED start flashing faster.
Completion of the charging
1. As soon as the fast-charger switches tot he constant-voltage mode, typically min. 4
LEDs are lighting and the 5th LED of the battery is flashing, the temperature controlled
fan can stopp.
2. If the battery is fully charged, the charger stopps.
The green LED lights permanently or the red LED is flashing! Turn off the charger and
disconnect the wire from the battery and cap the charging plug.
Attention:
Don’t worry, if the charger’s LED flashes red and all LEDs of the battery are lighting.
That could mean that the Battery-Management-System of the battery stopped the
charging process to balance the single cell voltages of the used cells. Your battery is
fully charged anyway! This ist o enlarge your batteries life time and security!
