Default Eneloop NIMH Receiver Packs

Has anyone used these as receiver packs? I am thinking of using them in a 30cc gasser running digital servos.

Thanks for any advice.

I have been told (by the guy that runs ? Hangtime hobbies) that this is not a good choice for receiver packs as they are not stable enough. He said they are great for transmitters though.

I have heard folk say life are the best for your set up possibly with a regulator.

Look at hang time hobbies (or maybe it's runtime?!) and email the guy your application. He will the set up including leads etc etc.

Depends on the maximum current demands. The Eneloops have a slightly higher internal impedance than other types of batteries. If the current peak demands are withing limits, they will work well for the receiver.

As a rule - don't
Tho these are excellent cells for low current devices -the internal resistance does not like large instant power demands and this could stop a 2.4 rx dead in it's tracks. ANY 24 rx
On low current demand they are fine but always check power /voltage under load with ANY 2.4 equipped model (the little 6400 bind n fly rx are about the only exceptions)\
In your example -do NOT use em - go for low resistance sub c NIMH - or A123 or similar cells.

In my large planes i am using NIMH in transmitter only.I still use NICD for receiver packs 4.8 volts.I do not use 6.0volt packs.I don't run high high torque sevos and i don't do 3d flying.I use 1500mah NIMH tx and 1400mah Nicd in rx.

I have read where Eneloop batteries do not like big demands.  So I use 6V batteries and high capacity configurations that would be otherwise sufficient to withstand the demands.  I have not as yet had a problem.

hi,
I have several 30cc size Warbirds, I run 2 Eneloop packs in each model, both 5 cell packs, plus a 4 cell pack for the engine, never had a problem,

BUT, it depends on the size of the digital servos you are using and the type of model you are flying, the type of radio, all you have said is 7 digital servos, more info would help.

I have a bird with 5 8611 servos (high torque digitals) and flew it for about a year on 2 5 cell eneloop packs. I change to the A9 TX that gave me real time battery telemetry. About halfway through my first flight of the day, the batteries would drop to 5 volts under load. Did not lose the plane, but it did make me change out my battery. I now use those same batteries in a Telemaster with 6 standard analog servos. My battery voltage never sags below 6 volts at any time during my flights, even when doing snaps, rolling loops and such. I use the eneloops cause that is what I have laying around, but I will not buy any more for RX packs.

I have also been running some large trainers (5 standard servos) with 2000mah Eneloops and 2.4 with never a problem.

Where did they get this information on the Eneloop?

There is a nice discussion on them on the hangtimes website. Probably the most authoritative info you will find on batteries.
