Ozito PXC 18V 2.5Ah Battery and Charger PXBC-25B - Kit $24.98 @bunnings.
Seems a good price for battery and charger kit.
Don’t know its difference with another kit 25C which is $69

This is obviously a cheaper version of the other 2.5Ah battery so it's likely using budget cells and maybe electronics, but for the money I'll take it. I did open it up and I can't see a brand name on the cells but they are actually 2600mAh 20650 cells, not the usual 18650s.
