So I had this xtar single battery charger, nothing fancy. i think i may have even gotten it for free. either way. i have a dual port charger that i use for all my batteries and this single was just sitting around. then i cam across this battery volt meter... a little unscrewing, soldering, hole cutting, re screwing, super gluing... and this is what i came up with.

i have a couple of mods i switch off from at home and i have enough batteries for them, plus like 2 extra, the thing was that i use a zmax, and a silverbullet. i switch off between them all day. now instead of checking battery voltage in my zmax, unscrewing the bottom, inserting a new battery, turning it on, cycling though the menu, testing the voltage... i just slap a battery in my little cradle here and bam, instant digital voltage readout.
