Decided to use 18650 3.7v 67mm unprotected cells.
Gutting the battery tray is going to be time consuming I think. Enough has to be removed for the batteries to fit. Battery tray is 140mm end to end. Just enough room to put contacts at 1 end.
After each use the batteries will be tested before and after charging in a 4 battery holder charger.

Simple design... but time consuming to make
