44 VOLTIC VLI Series
Charging
Attention!
Please note the following notes when charging the battery:
• Use only LiFePO4 cell chargers with a closing voltage according to the Voltic battery data
sheet!
• Even simple Lead, Gel, Acid, and AGM battery chargers can damage the LiFePO4 battery
at the first connection!
• Note the maximum charging current of your battery, this must not be exceeded at any
time!
• Stop charging when the BMS stops charging and check the battery and charging
parameters!
• Disconnect the charger if this is not in use for a long time!
• Use only Voltic approved or approved LiFePO4 chargers to prevent damage to the
battery!
• Charge your LiFePO4 battery as soon as possible at a low charge level of approx. 20% or
after a shutdown due to undervoltage to ensure maximum service life!
• Charge your battery before an application!
During delivery, Voltic batteries are charged between about 40% and 80%. We therefore
always recommend that you charge a new battery completely before use. Please observe our
specifications for parallel or serial connection of the batteries!
Charging at low temperatures
Our BMS also controls charging at low temperatures. The normal charging range is from 0°C
to +60°C, where the battery absorbs the complete charging current.
If the temperature is outside this range, the charging current is reduced so that the battery
can either heat up slowly or cool down.
This will extend the charging process.
