Xtrema , Hyperion or FMA ??

I'd avoid the 977 unless you are only charging 2s and 3s packs of 2500mah or less. Other than that its severely underpowered and I have read that there are actually lipo manufactures that wont cover warranty on their batteries if that model or any older MRC chargers are used. The 977 maxes out at 3A for a 2s pack and 2.5A for a 3s pack and cant charge lipos with cell counts over 3.

I have the Hyperion 0610i and my complaint was when I would try to use the balancer I would get the battery connection error, I called Maxamps where I bought the charger and they were no help, you need to hook up the charger, battery and balancer in a special sequence, I tried every possible combination and nothing worked...it charges fine when I charge through the bannana output jacks, and I balance the packs before I charge with a seperate balancer and I have had no problems, the first couple of times I did this I would also try balancing after charging, and they would be perfectly balanced so I only balance berfore I charge.

The sequence really isn't that special.

Once the charger is on and set for the right battery, just do this:

1) Plug in the balance tap
2) Plug in the power lead (within 12 seconds of step 1)
3) Hold down "Enter" to start the charge.
4) Hit enter again when it asks you to confirm the cell count

If that doesn't work, then something is broken.

I can actually make a quick video of the process if it would be helpful. Just let me know.
