FMA Direct are releasing their SkyVolt system shortly.Now expected mid september i think.They use the same cell balancing circuitry and charger technology as the scorpion but without the LVC so like the balance pro but in 4s and 6s.The charger charges up to 6s.They'll be available in the 20c Kokam cells.YOu could use a pair of their 4s in series giving you only 2 packs to charge instead of 4.

This is what Greg Covey said on another forum:

" The 4-cell, 3.2AH Kokam packs are pre-wired to a special connector so that each cell can be monitored during charge and discharge for optimal safety, longevity, and investment security. The Skyvolt packs are used in conjunction with Protection Modules; one for charge and one for discharge. This new approach in Lithium cell safety and protection will be available soon from FMA Direct.

The Cell Pro 6s Discharge Protection Module (DPM) can monitor up to a 6s Skyvolt pack to provide a warning when the voltage gets low and use any ESC to pulse the throttle signal to the motor to alert the pilot that it is time to land. There are two dip switches on the DPM but Switch #1 currently has no function. The units will work out of the box without doing any setup, but they perform optimally when you tell the units which way low throttle is using Switch #2 and use the learning procedure mentioned in the manual.

Note that two DPMs can be daisy-chained for up to 12s configurations.

The Cell Pro Charge Protection Module (CPM) is used with any Lithium charger to monitor individual cell voltages and disconnect the charger when the first cell reaches 4.2v. This extends pack life by preventing overcharging. Note that this does not balance all the cells in the pack, only the Skyvolt Charger (not shown) provides true cell balancing during a charge."
