Functions
1. This charger is suitable to charge a 36 Volt Li-Ion battery pack,
10 cell in serial. The max. charge current is 4 A. The max.
capacity of the battery pack can be 25 Ah.
2. The charger has an overload, short circuit, overvoltage and
wrong polarity protection.
Overload protection (cut off if the output current is higher than 7A)
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
50V)
Wrong polarity protection (cut off if battery with wrong polarity is
connected to the charge cable)
3. This charger has an additional charge capacity counter that cuts
off the charge after 25Ah are charged into the battery pack. This
is also indicated as error.
4. 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.
5. Errors are shown by the flashing red LED.
Operation
1. Before first use please check the parameters of the charger and
your battery according the rating label or the manual to ensure
the accordance.
2. Check if that the local main AC voltage level is suitable for the
charger.

3. For a function test plug in the mains cable into an AC mains
socket. The green LED will flash slow, that indicates stand by.
4. Now connect the DC cable to battery pack. The green LED will
flash equally and shows that charging is started. If the battery
voltage is less than <25V the charger will start with a pre-charge
current of 500mA. If a battery voltage of >25V is not reached
within 30. min. the charger will cut off. This is indicated as error.
In this case please contact your battery supplier. When the
voltage is reached, the charger will automatically switch to fast
charge.
5. If the battery pack is fully charged the charger cuts off. The green
LED will give a steady light and indicates the full battery pack.
With some batteries the charger will start after 2 seconds to
charge again. It will stop a few seconds later when it recognizes
the fully charged battery. This can repeat again. It will not
damage the battery.
6. 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
until recovery.

Remarks
This charger has a wrong polarity protection. The right polarity is
the base that the charger generates a charge voltage. Depending
on the battery safety board, a battery pack that is discharged
under it’s nominal discharge voltage can’t be charged again. In
this case please contact your battery supplier.
Error through reaching the capacity limit or the pre charge limit,
will be reset immediately after removing the battery. Error through
short circuit or wrong polarity will be reset automatically maximum
1min after removing the Problem.
