a few battery questions...

[Lmao45]

okay, so I've been looking into getting rechargeables for my reciever in my nitro and have a few Questions...

1) What is the advantage of a lipo over a Ni-Mh, or Ni-Cd?

2)What Would happen if I ran a 9.6v instead of 7.4v?

3) how long do Rechargeables last as compared to a set of AAs in the reciever of a nitro?

4) How long on avg. do rechargeables run (Time)

1. The NiMH does not tend to develop a memory like the older NiCd packs.

2. Most receiver packs are 6 volt. Any higher and you run a very good chance of blowing up your receiver.

3. I don't know about how long alkalines last because I never run them. I do, however, tend to get over an hour on my stock Revo or Baja 5b stock RX packs.

so, this narrows choices down to 2 packs, LiPo, and Ni-Cd..... Which should I go for?

You don't want a NiCd pack. Outdated battery tech. It's like using a cassette player to listen to music. LOL

Your choices would be between LiPo, LiFe or NiMh for a receiver pack.

Do you have a charger capable of charging LiPo and/or LiFe packs?

What nitro rig is this going into?

I have no chargers, It's going into a 1/10th scale nitro stadium truck

I've used both LiPo and NiMH RX packs. There is no real difference in runtime with both batteries having similar MAH ratings.

You DO have to be careful with the LiPo's though... as you can't take them below certain voltage per cell or you damage the cell.

I'm back running just NiMH packs.. but i run LiPo pack in my transmitter. Gotta love going 5-6 months without having to charge.



I use the Dynamite Vision Peak Ultra charger. Fairly inexpensive, and it does NiCD, NiMH and LiPo.

a lipo pack will run a constant voltage for its entire battery cycle and then drop off suddenly at the danger point. nimh on the other hand, slowly loses voltage (power output) as its power cycle goes through. in my opinion going nimh isnt just cheeper, but using the capabilities of lipo on a receiver really isn't needed unless looking for top notch performance throughout an entire race. if your bashing, or just racing for fun and not as a "job", id go nimh.

The big advantage with LIPO RX Packs is run time really. I run a 1500mah LIPO RX Pack in both my buggy and truggy. After a full race day, which includes practice, (3) 6 min heats with warmups before, and a 20-25 min main with warmup....I have never put more than 750mah back into the pack. Most weekend....I put @ 500mah back into it...and that is for probably 50-70 minutes of runtime with digital servos.

They weigh less, keep a more constant power source, and seem to last way longer than their NiMh counterparts. The only downside is you need to run a LIPO Regulator or buy high voltage servos. NiMh is still great tech as well. They are cheaper, heavier, and way less volatile. You can't go wrong with either battery type really, just stay away from NiCd...like robmob said it's outdated tech for sure.

Okay guys, thank you very much for all this help.... since I am just bashing I'll just stick with Ni-Mh packs... because I don't need any extra equipment or checking the battery for voltage, or special (and expensive) Charging stuffs.

I would use a LiFe receiver pack. All the benefits of LiPo without the perceived dangers and they last up to 4 times longer. You also will not need a regulator.

They come in both flat and hump style packs.

yea forgot about the LiFe stuff. Have not tried them myself, but a few friends use them in their boats and have nothing but good things to say about the A123 stuff.

LiFe is actually an awesome choice as well if your charger supports it and you can find one to fit in your radio box. Like rob said...all the benefits of LIPO without the dangers.

so wait... the cell won't be damaged if it reaches a low voltage?
