Rechargeable Batteries for a TX

Recommended Posts

I have a FlySky FS-GT3B and am getting bored of keep replacing the 8 AA batteries that go inside it. This is probably a really dumb question but can I add in some regular rechargeable AA nimhs and recharge it with my Fusion Battery charger that has the right cable and I can charge at a rate as low as 0.5A ?

Is there a standard calc for charging according to MAH and total v ?

Simple answer is, YES you can run your radio on AA size NiMh rechargeable batteries.. You could also go to a LiPo battery if you liked, but you would need a LiPo charger to charge it.....

As for charging with the Fusion charger, you will have to try it and see.. 0.5Amps sounds OK as a charging current, but not knowing what the delta peak setting is you could slightly overcharge the batteries.. Likewise, unplug the AA batteries as soon as the fast charge cycle is complete, as the "trickle charge" that turns on when the fast charge finishes, could still supply enough amperage to overcharge the small AA batteries....

I use Sanyo Eneloop for my transmitters. They are trouble free and hold their charge over months. I charge them with 2A, but 1A or 0.5A would be fine, too, as long as the charger supports delta peak detection.

My first RC battery charger had jack for transmitters. But it did only slow trickle charge on that jack, maybe to protect the transmitter battery wiring and insides from overheating I guess. I only do fast charging when the batteries are pulled out of the transmitter and put directly into their dedicated charging device.

My fusion wouldn't even detect the batteries when plugged into a flysky or my eurgle tx. But I use a 12v 500mah wall charger now which came with one of those 12v jump packs and it works a treat.

Many (probably most) Tx charger inputs are protected by a diode against charging with wrong polarity, which sometimes causes problems for advanced chargers as they "interpret" the diode as a open circuit (= no connection). For a simple trickle charger, it doesn't matter.

I thought this maybe the case. Since it was the only thing that the fusion charger would have been good for with me as I have converted to pretty much 100% lipo I sold it and ordered an new Turnigy B6 Pro.
