I currently use an SP4 pack from work and I call it GR05-BAT-001

1. 4 2200 mAh 16V battery pack

2. Battery pack comes with a bq20z95 fuel gauge. Latest impedance track technology.

3. Battery charger comes with an LCD to display status of battery charging states.

I am currently working on my own design for this pack. When complete, I will post pictures for your viewing pleasure!
