[QUOTE="karelian65, post: 550950, member: 9224"] The disposable lithium batteries like the Energizer start at 14.8 volts in the standard battery tray, effective but costly. 14500 cells are 3.7 volts each and roughly 800 mah max. That equals 14.8 volts but only 3200 mah. Modifications will still need to be made to the standard battery tray. 4 x 18650 top out at 16.4 volts and roughly 3000 mah per cell... Tdi Sl machines use 500 mah, that is per hour. You can see why on a Tdi Sl the 4 x 18650 battery pack is the ultimate. Sacrifice a twenty something dollar battery tray and do the conversion. Invest in quality 18650 cells and a charger, still under a hundred Australia dollars. It will serve you well. All the best. [/QUOTE]
