There is a lot of bogus mation being passed around.
1st, the JR radio's do have reversed polarity, if you had plugged the Hitec charger into it, it should have blown the fuse.
2nd, reverse charging the Hitec radio with the JR charger could have damaged the cells beyond repair, the only way to know is to give them a forming charge ( 18 to 24 hours on the slow charger) Then cycle them 3 to 4 times and check their capacity each time, if they come up to capacity after the 3rd cycle, then they will be OK, if they don't, replace them and start over with the forming charge.
3rd, the Hitec radio has a jumper that will not let you DISCHARGE the pack through the radio jack, any peak detection charger will charge them ok, but won't let you "cycle" them until you jump the diode. ( Check my web site for directions to jump the diodes www.siriuselectronics.com )
4th JR radios don't use diodes, they have a fuse instead, some are user replaceable and some need a tech to replace them.
Best advice I can give you is, "Don't fly that pack until you have made SURE it will function correctly".

If you would like to discuss this further, I'll be in the shop all day tomorrow 800-532-0092

Y'all know I'm no electronics whiz, so I'd appreciate a little advice if any is necessary:
I just charged both of my JR TX's for several hours using two wall chargers. One charger was stock JR, the other one I THOUGHT was my other stock JR wall charger..... but I now see that it was actually a Hitec wall charger. The radio that was on the Hitec charger had zilch, wouldn't come on, LCD display didn't even flash for a second. Seemed very weird at first, but once I realized it had been on the wrong charger, things started to make more sense.
I've now got the uncharged (mis-charged?) radio charging on the JR charger, as was the original intent.
I seem to remember from my days of wiring various other chargers that the wall charger polarity on a Hitec and JR chargers might be opposite.
Any reason to expect that I've done any damage to the battery? Anything I should be doing or checking?
I already put the 'correctly charged' battery in the TX that was on the Hitec charger and everything works fine.
Thanks in advance for any reassurances (or horrors if warranted) :-)
