Ive been thinking of building one of these, i have a battery pack like you have there lying around for whatever reason, and my MX700 just broke, and the power connector on it is identical to the one i use on my H140.
Should be easy to build, right?

I have a battery pack that will do 3 batteries. I`ll probably get 3x2300mA rechargeable batterys. So thats 6900mA. Unfortunatelly, where im buying from doesnt list what voltage they have or the mA output/hour.
So getting the calculations exactely right will be a little hard.
I know that my H140 takes 5v/2A from the charger to charge, and i would like my charger unit to actually light up the charging light. So.
As im unsure of the specs of the batteries; will the H140s light, light up when i plug in the battery pack?
