Exactly which type of batteries for 3.7v and 6v?

The SB is made to accept a maximum 69mm battery length. Are you able to get it together at all?

Just a thought, is SB V1.1 and V1.0 the same length? I have V1.0.

Just found out I need to get the V1.1 bottom in order to go 6V!

yeah you must have version 1- which would need the sleeve or adapter or whatever it is. I believe the v1 needs cr2 bats. But the LiFePO4 fit perfectly in my 1.1. BTW I love the Tenergy LiFePO4 bats- they are awesome. And to get 6 bats and a charger for 27 bucks is pretty good. Especially since they are rate at 2000 chargers (dont know how accurate that is?) But I am only using 4 of them and I have the other two as back ups. And plus I have my 3 sets of clearance RadioShack 3v 400mah in rotation also.

Yes those ill work for your SB, those are the exact ones I use.

Can you also tell me what charger you have? I Bought DealExtreme: $12.30 UltraFire 3.6/3.7V Battery Charger but the 18650's (sku20392) won't fit properly and those batteries should be even shorter than the ones you are using.
