The charging time depends on the charging status at the start of the
charging cycle. If the capacity is still 40%, 6Ah must be charged. The
charging time is then around 3 hours x 2A + around 1 hour = around 4 hours.
The charger can be continuously connected to 230V, even after the battery
is fully charged. Never charge the battery pack at temperatures below 0°C.
At -10°C, a protection device is activated which makes charging impossible.
The battery can be discharged or used up to a temperature of -20°C.
The battery can also be charged by solar panels if they are connected to a
charger that is suitable for charging LiFePO4 batteries. We have the XS20s
MPPT Solar charger in our program. Because of the MPPT technique this
charger gets the maximum efficiency from your Solar panels.
You can also charge the battery while driving. For this you need to use a so-
called charge booster, see paragraph 3.4.
