No, PowerPacks with their lithium-ion cells can be charged for as short a period as you like or as long, irrespective of their charge status. The PowerPack’s integrated battery management system, combined with a Bosch charger, protects the battery from overload when charging. Interrupting the charging process does the battery no harm. An important point to bear in mind is that eBike batteries should only be charged with the right charger because irreparable damage might otherwise result and warranty or guarantee claims might become invalid.
