Saw on anazon a li-ion 2200mAh battery and bought it. ?Fits great but is not happy with the drop in charger. ?Sat over night blinking red. ?Close look on battery says needs a lithium ion charger only. ? Uh oh…. Now what? ?

BatteriesAmerica.com has an intelligent Li-ion charger.

Yes - proper charging of Li-Ion - or NiCd or NiMH - require chargers with differing charge algorithms ...

Chargers for Li-Ion battery is nothing very special, the battery normally has the BMS circuit built-in. This BMS board manages or takes care of making sure that the cells inside the battery are charged equally/correctly and it ends the charging when the charge level is full to prevent damage.? My guess is that the drop-in charger does not deliver sufficient current or voltage.?

Hi Chuck,
I also had battery troubles in my FT-60R recently purchased.? The stock battery performed like your battery 1, but would work for a while if I set the transmitter to low power.? I ripped it open and found 6 NiMH AA cells tabbed together in series.? After charging and load testing, I found that 4 of those cells are good; the other two take a charge but self-discharge after just a couple days.? I bought 2 flat Li-Po cells to put in that case.? I plan to charge them with a simple charger regulated at 8.4V with a resistor to limit the charge current.? It won't charge quickly, but will charge fully that way.? My FT-60R also came with an enclosure containing individual NiMH cells.? Some of those cells turned out to discharge themselves over a week or two.? So I'll supplement the 4 good ones from the original pack with 2 others that are able to hold their charge.
