1. Safety Rules and General Warnings
●Persons, which are not able to use the device in a safe way, because of their physical, sensory or mental competence, or
because of their inexperience, should not use the charger without control or instruction of a skilled person.
●100- 240 Volts alternating current, device is not suitable for children –Danger of life.
●Ensure for enough air ventilation while charging.
●The charger is exclusively designed for rechargeable Lithium-based batteries and must not be used for other purposes.
●Please consider the charging instructions from the battery manufacturer before charging.
●DO NOT OPEN the device. Repair work must only be accomplished by authorized companies or specialized technical staff.
●If the mains connection of the device is damaged, it must be replaced with an original wire which is available at the manufacturer or
costumer service.
●Never place the device on top of the battery while charging.
●Protect against direct solar radiation and temperatures over 40°C.
●In case of obvious damage or malfunction disconnect the device from mains supply and protect against unintended reconnection.
●The DC cable must not be cut, shortened or extended.
●The charger is not designed for higher environments as IP 20.

2. General Information
This microprocessor-based IP-65 Lithium Battery Charger was especially developed for the outdoor use and for situations where
water may be present. It can be used to charge any Lithium- based battery.
With the 4-step charging program the battery will be charged safely in a fully automatic mode. The output of the charger is
electronically protected against short circuit. The charger is able to recover deep-discharged batteries.
Colored LED's are used to indicate charging status and errors.
3. Special Features
●Short circuit protection
●LED's to indicate operation and charging status
●4-Step charging technology with automatically restart charging
●Automatic shut-off at too high temperature
●Indicating a non-chargeable ('dead battery') condition

5. Operation
ATTENTION:
The DC cable must not be cut, shortened or extended
Before operating please make sure that the power cable and the charger including the charging cable show no damages and make
sure that the mains supply complies with the specification.
Please consider the charging instructions from the battery manufacturer before charging.
If you want to connect the charger to the battery, please have a look to the following points:
Make sure that the device is switched off and disconnected from themains.
Make sure that the charger is connected to the battery.
Connect the charger to mains supply.
6. Charging the battery
The charging process starts automatically and runs through the following four charging phases:
1.charging phase: Auto Wake-Up
This charging step is indicated by blinking alternately of the Charge-LED (3) and Full-LED (4).
Explanation: The recharge phase starts automatically at deeply discharged batteries (where the BMS is off). During the pre-
charge phase, the charger use controlled current pulses. That tries to reactivate the BMS and bring the battery in a voltage where it
is possible to start the charging process.
2.charging phase: soft start
This charging step is indicated by constant lighting of the Charge-LED (3).
Explanation: During the soft start phase the charger reduces charging current, in order to extend battery lifetime.
3.charging phase: constant current
This charging step is indicated by blinking slowly of the Charge-LED (3).
Explanation: During the constant current phase, the battery is being charged to 80% of its capacity.
4.charging phase: constant voltage
This charging step is indicated by blinking quickly of the Charge-LED (3).
Explanation: During the constant voltage phase the battery is being charged to its maximum capacity.
If the Full-LED (4) is constant lighting, the battery has reached the full capacity. Should the battery stay connected to charger
the auto- mastic restart, starts after 7 days or the battery voltage is under 4V/cell (Lion-Battery) or 3.4V/cell (LiFePo4-Battery).
Disconnect the charger from the battery:
a) Disconnect the charger from the mains supply;
b) Disconnect the charger from the battery;

Charging advice:
If the charger will be disconnected from the battery during the charging process, the charge current will be interrupted mime-
daintily. In that case please disconnect the charger from the mains supply. For starting a new charging process please comply
with the relevant points.
For increasing the lifetimes of the battery please do not stop a charging process before the battery is fully charged. The
charger will automatically stop the charging process

8. Errors and Troubleshooting
Table 1: General errors:
Error description
Solution
No LED lighting or blinking after connecting mains
