I always use Eneloops. You can get them at Costco. They are rechargeable and last a long time. They also discharge at a lot slower rate than most others while not in use.

Both of my main radios have HrydriMax 1650 MaHr packs, and I have a Hobbico cycler/charger....they're probably each close to 4 years old, and still work well....

btw....I call them Radios to avoid the confusion with speed controls or ESCs, as most people do....

Rechargeables never seem to last as long as regular batteries, I use rayovac batteries.. super cheap think its 10 bucks for 30 of them, they last almost 3 times as long as rechargeables.

I use rechargeables (NiMh) in my receiver because the servo's drain batteries quickly. In my transmitters I use no-name alkalines. I can get a pack of 50 AAs for a bit over $12. Not all no-name batteries are good, but I've tested the ones I buy (initial power measurement and monitored for longevity) and they seem to be a good quality battery.

The NiMhs are actually a pain......all charged up, ready to go, plans change, a week goes by, batteries are no longer fully charged....a pain.

Not sure how NiCd technology has changed, but I never had much luck with AA-size NiCds. They always seemed to develop internal shorts and wouldn't take a charge. Never had that problem with C or D NiCds. Now D-cells in your buggy....that would add some weight!!!

Hard wiring the pack is the best way. Those cheap battery holbers can melt fast if you charge too fast. What No charger input on the radio.[] You can always put a JST connector on and still remove it. That what I do with all my radios.

Old-school yellow Sanyo NiCd AA's. I like being able to just plug the charger into the side of the controller. They work fine, even if they're just 700 mAh. Never had a bad one, they are all I ever used.

Been Using & Charging those Batt's for Years (If your Charging your batt's fast enough to melt the Holder your Charging them to fast and at Too high Amps)

I just pulled the AA battery tray out the base of my 2PL transmitter and soldered on a servo plug and got a Lipo transmitter pack . Cost me $24 for a 2200mah 11.1 pack.

I use the stock Sanyo NiCad batts for my 3PKs, those have lasted me eversince I bought the radios.

I also have the Futaba Megatech AA batt tray (not sold in the US, only found in Asia), and if ny NiCad TX batts are on the charger, I slap in the Megatech AA batt tray loaded with 1.2V NiMh AAs and put that in.

Yes, home use NiMh AA 1.2V batts are pretty lame in that they DO NOT HOLD A CHARGE over time [].

Its more or less use them after you charge them within a few daws, or live with half of their capacities dissipated. I do not know why NiMh bleed off capacity way too fast.

i use energizer 15 min rechargeable in my TX. I don't know why some of you guys have trouble, probably crappy batteries... I can leave my TX for 2 weeks and when I go to drive I still have plenty of power....

The HydriMaxes I use last quite a while....a charge will last me a full weekend most of the time unless i do something dumb like put the radio away in it's case without turning it off first.....but they charge back up pretty quick....I have an Onyx 240 that will charge radio and Rx packs as well as the 7.2 packs for my spin start, and the 3300 NiMh packs in my E Maxx....

That's using your head...great idea[sm=idea.gif]! I am going to try that, the price is right and no more AA hassles.

A lipos "C" rating, is how fast you can safely discharge it. You take the C # times the capacity.(then take off the last 3 digits for the amp rating) So a 3000mah 25C pack can safely be discharged at 75 amps.

You can draw more than that rating for short bursts, but if you draw more than that for extended lengths of time, you will shorten the batteries life.

something like a transmitter doesn't need a high C rating battery, since they typically draw less than 1 amp (normaly around 500-750milliamps, or .5-.75 amps))

I think the regular batteries work but they do cost a lot of money

I have'nt used alkalines in an RC transmitter in over 20 years....they die quickly, and if you leave your radio on when you put it away, there goes another $8-$10....

I switched to a LiPo for my M11, and I LOVE it. Lighter, and lasts longer than 8 aa's. And it will probably last me for many years.
