9.9 Battery current limitation
The battery current limitation is user adjustable according to the battery capacity, in order to ensure a battery reloading
between 0.1C and 0.3C as advised by the manufacturer. The thresholds are 25%, 50% and 75% of the nominal current.
Selection is made by 2 microswitches. The charging current default value is set at 75% of the nominal current.

9.10 Temperature compensation (according VdS2122)
Thanks to a battery voltage compensation system, the battery charge characteristics can be maintained within the
specifications limits provided by the battery manufacturer under the whole range of temperature.
The temperature is measured by a sensor placed as close as possible to the battery.
Voltage values versus temperature values are:
