oh had the 100w 12v orsram xenophoto already and will be at SLT later today to look for parts, but unfortunately, no further funds for the maglite yet .....
Actually SLT sometimes is quite limited; for e.g I can't find li-ons at the batt shop there. The guy say no one brings in.
Mine are charged individually (I have 2 chargers tho, a 30min and a 3hr). I almost bought a pack charger but never got down to it.
My batt holder quite roughly put together... not very good at all... but I'll try to help what I can Emilion released some Li-on D cells 5200 mah and I believe now another member is gathering interest also; that would be much easier. Just 3 pcs in mag 3D and you get your 12v, and the 5200 mah can easily take the 8-9A the mod requires. Less sag and no self-discharge also.
I can't remember the results on Silverfox's test with the Eneloops, but they would be required to do 4C to power 8-9A.
