E-flite Celectra 1S Charger question.

[Old 'N Slow]

HI! I recently purchased a Blade 120 SR helicopter, and it came with this 1S LiPo Celectra charger.
This helicopter uses a single-cell 500 mah LiPo battery.

I've flown the heli maybe 10 times, alternating 2 E-fliite 500 mah batteries that this heli uses. So each battery has been used/charged 5 times.

Charger seemed to work OK. Little bit wonky getting the charger to start charging, have to push the button several times sometimes...fine. When the charge was done, the charger indicated this by flashing all of it's LEDs. This *kinda seemed* to match what the manual said...

Until I used it charge a couple of "Thunder Power" 160 mah batteries that I had been using in my mSRx (previously charged with a single-port battery/AC charger unit for smaller E-flite batteries). Set it to charge at .2 amps, takes about 30 minutes. It was then that I noticed that when these batteries were finished charging, the LED indicators did a sort of side-to-side indication - what I call the "Cylon Effect."

I now understand that the indication of all the LEDs blinking together indicates that the batteries are *almost* finished charging, not *fully charged', as I first thought.
No matter how long I leave either of the 500mah packs on the charger - at 0.7 amps rate (the highest possible rate on this charger), as instructed, the indicators never get to that side-to-side indication that the charge is complete.

Just wondering if anyone has had similar experiences with this charger, or has any opinion of it.

Thanks!
