4 single battery cell holders for Li-Ion 18650 of either type in picture arranged to fit on a flat piece of plastic will power a Whites SPP, TDI SL or TDI Beach Hunter.

Both holders can accommodate either a flat top or the longer button top protected cell.

18650 cell battery tray for SPP + TDI SL will not fit the TDI Beach Hunter as the battery compartment on that model is different.

Modified a Whites AA battery tray to hold 4 x 18650 Li-ion cells, any of the current size 18650 cells will fit included the longer protected ones.

This battery tray will fit all 3 of Whites PI models, SPP, TDI SL and TDI Beach Hunter.

Heat and curve slightly the original lid and that to will fit.

Have now modified the Orange 3 cell tray so it also can fit the TDI Beach Hunter.

For the fun/challenge of it, made a 4 x 18650 cell tray just for the Beach Hunter.

TDI Beach Hunter is an SL in a water/dust proof box, with extra battery power also useful for Gold prospecting on hot WA ground.

Main reason for the battery case mods was to have a steady voltage and high capacity power supply, more so in the Beach Hunter as water hunting have restriction on how much you want to carry, like a spare battery.
TDI SL and SPP have more space and different tabs than the Beach Hunter that prevent the battery from being inserted backwoods in the battery compartment.

Without making cut outs in the case bottom it was easier to fit the 4x18650 cells in the middle and make a slightly flexible lid that could curve over the cells and thereby allow the same battery case to be used in all tree detectors

How does this affect the total weight of the detector?

Nice design....the photo is deceptive but do the battery contacts on the tray line up with those inside the detectors battery compartment? Sorry for asking what sounds like a stupid question !
Thanks
