When I connect my range extender battery to my bike the additional charge is not reported on the Karoo 2. The bike itself reports the extra power available as an additional percentage on top of the internal battery charge - the range extender is half the capacity of the internal battery so if both are fully charged the remaining battery percentage is 150%. If the internal battery was at 56% and a fully charged range extender is plugged in the remaining capacity would be 106% etc.. The Karoo only reports 100% or in the case of the second example, 56%.
