Not true...
( FYI: Most 4.8v chargers produce closer to 5.4v unloaded anyway... )
As I said I TESTED the charge on my packs and while I'm short of full capacity, as the wall wart chargers cannot sustain the load caused by the pack as it approaches full charge, I'm within 90% or better of full charge.
On my larger packs loosing 50-200mAh is not a big deal considering how little adverse effect this has on the packs. It's like trickle charging your batteries, as far as the chemisty goes.
I charge AA sized 2000mAh 6v Hydramax packs with my JR chargers all the time. I get at LEAST 1700-1800mAh out of the packs when tested under load which is well within what I expect.
BTW: I've tried those 2/3A packs and I find that no matter what you use to charge them the cells do not seem to be large enough to sustain the draw from the servos.
I've been underwhelmed with their performance after testing several brand new Duratrax 2/3a 1400mAh 6v packs on my ICE and TC-1030 charger's testing regimes.
While this may have worked for you, I cannot in good conscious recommend it to others, unless the test their own results.
I have not been able to consistently replicate your results with my collection of wall chargers and various AA or 2/3A 5 cell packs.
(FYI:I generally stop flying when my 5 cell packs reaches 6 volts, so I don't see how an "unloaded" charge voltage of 5.4 helps charge a pack.)
I'm phasing out my 2700 AA packs in favor of 2/3A 1400-1600mAh packs, much less voltage drop under servo load from what I've observed. No problems charging with any of mine using a Double Vision, Super Brain 989 or Triton 2 chargers. None are Duratrax packaged thou.
I will agree we have totally opposite results.
