The other day i crafted a battery from quantum storage and then tried charging it in a rf tools power cell it would take the power and didnt charge then i tried putting it in mekanism charge slots with no luck also
Rf toosl: rftools-1.12-7.31
Quantum storage: QuantumStorage-1.12-4.4.10
Mekanism/gen/tools: Mekanism-1.12.2-9.4.3.330

Just as a fyi it does not use the RF api, it uses the forge energy system that most mods support, there is still some other issues I need to resolve with the battery.

It does work for me, it's just that the tooltips don't update.

Fixed in 4.5.0
