Sounds like everything else is pretty much in order. How's the performance and run-time?

Here are some pics of the pack. I also scanned the instructions so everyone can have all of the information about these packs. From full charge in a touring car witha brushless motor, depending on your track conditions and gearing it will go 15 mins until the internal volatage cutoff will automatically shut it off.

I've done some testing on these they seem pretty decent. Attached is a 2 discharge plots I made at 30 amps. They are a little on the low side and there is a dip at the beginning of the discharge because these cells were sitting in my shop all night and were a little cold in the morning. Once the cells warm up a little (from discharging) the voltage rises a little.
Weight on these is about 8.5 Oz or 240 Grams. They are 1.83 in/46.7 mm wide, 5.4 in/137.39mm long .937 in/23.81 mm thick. Basically, almost identical to an assembled side x side pack. The low voltage cut-off that is built in does work and kicks off at 5.4 volts on the nose. Good for a safety measure but don't run them until they hit the cut-off if you can help it. It's best to stop once a noticeable decrease in speed happens. I think 5.4 V was probably chosen as 6.0 V would be too agressive and under load you would experience drop-outs - 5.4 V is a good number. Testing was done on a CE Turbo 35 GFX LiPo.

It's the Align balance plug.
I've been using this battery in 10th scale touring cars and buggies with brushed motors and no lipo cut-off. It's working as well as my Pro Match EP4200 packs with a CO27 stock motor. I've also been using the Hyperion EOS0606i AC/DC charger and that thing is awesome. Can't believe there would be a better all around charger for $150.

blinky is fine. they just dont provide the digital readouts like a integrated charger would.

Sorry fo the slow reply - been out of town a lot lately for the holidays. Yes I have done some comparisons. I'll post some more plots this weekend. BTW, my GFX seems to be a little stingy on the capacity rating. It's giving me about 4400 mah on these but also gives about 4400 mah on a brand new EP4600 pack that just came of the matchers.
I'll try to get some more data posted this weekend.

Anyone have any problems with the 2 hard case halves having some play?
If I press and release the front near the inputs the case moves about 1mm up and down.
Worst case, I'll just run a band of tape around it, but curious if others are like this?
