can someone please help me on choosing some batteries for my erevo,ive got a nue 15151y,waiting on my mamba monster,i was really wanting to go a123's but i guess they dont fit, what is the fastest and longest lasting battery that actually fit in the trays, i want it to be fast but at the same time still be raceable, whats a good setup for speed runs??? what would be a good setup for race?? 4c ,5c, 6c thanks for the help

2x 2s should fit. 5000mah would be the min I would go with. max-amps seems to be popular and is what i have in a 3s 8000mah configuration for my revo conversion

I picked up a set of Reedy 5000 lipos last week from Tower. They were $90 a pop and since I ordered 2 I was able to use a discount code. I plan on running them this weekend and see exactly how long of runtime I will get, using a Novak HV Pro 6.5 system.

I would suggest a pair of 2s lipos, at least 6000 mah. 8k is better if you can afford it. I use Maxamps 6ks on an HV6.5 system and it's plenty fast for racing.

I'd go with an Enerland cell based pack such as Hyperion, Polyquest, Flightpower, Trakpower, Thunderpower, NeuEnergy, etc. These are the best batteries available on the market right now. I'd go with a 4s pack for racing, and for speed runs you can run up to a 6s lipo, although you should watch temps when running 6s and you will probably need to change your gearing as well...

thanks alot for the help , sorry to be a dummy, do i get 2 three cell lipos to make a 6c setup??? two 2c to make 4c ??? what would be the best for the nue 15151y???

also do i want 2, 11.1v too give 22.2v, or 2 ,7.4's ????

I think you are gonna want between 40,000 to 50,000 rpms if the truck is geared like a regular nitro Revo. Take the kV rating of the motor you want and divide into whatever rpm you would like and that should tell you how much voltage you need.

how much runtime and what kinda speeds would i get out of 2 of these,,MaxAmps Lipo 5000HV 11.1V E-Revo on a nue 15151y and mamba monster esc ,stock gearing ,do i need to get a pinion?? or can i use the stock one? thanks all,....

One thing - there is a difference between "2s" and "2c".

2s is the number of cells - 2 in a series. They are 3.7v per cell and you add the voltage for series, so 2s is 7.4v, 3s is 11.1v, etc.

"C" rating is the discharge rating of the pack. "20c" means that a pack will continiously supply 20 times the amp capacity of the pack. For example a 20c 5000 mAh (or 5 amp) battery can supply 100 amps sustained. Ratings are a bit suspect in some cases, packs won't always deliver what they claim, but it's still a decent gauge of quality. Also note that means that given equal C ratings, a pack with a higher capacity will provide more amperage - 20c 5000mAh gives 100 amps, 20c 6000mAh gives 120 amps.

A pair of 3s 11.1v batteries is the same as a single 6s pack, for a total of 22.2 amps. I've never run an E-Revo with the much voltage but I imagine it's going to be insane - probably too much power to race with if that's your intentions. It should be good for bashing though since it will probably stand up without having to get far into the throttle.. in fact you might have to dial some of that power out to keep it from flipping back onto it's lid.

You will want to gear to temperatures with that much power, rather than speed. You're going to have more power than you'll know what to do with anyway. Get a temperature gun (Tower sells a Duratrax Flashpoint for around $20) and check the esc and motor temps every few minutes when running. You're probably going to want to go 3-4 teeth less on the pinion from stock at least - maybe more. That's a lot of juice.

hi guys,
need your expert opinion of what pinion to use in my setup:

e-revo stock spur 68T
mamba max esc
feigao 9xl motor or 8xl
4s lipo 25c
pinion - __T? or ___T

hoping for your utmost help.

putok-Ask on www.rc-monster.com , they sell mod1 pinions which is what you will need for the XL motors. I'm not exactly sure what pinion to use but ask on rc-monster and they will definitely help you.

i just ordered the 5000hv 11.1v packs from maxamps i have a mamba monster,and nue 15151y ,are these batteries gonna be too much??????

maxx amps 3s 5000 lipo is a good choice. to get a longer runtime you could have went with a maxx amps 3s 8000 lipo.


with the neu motor and the mamba monster max esc you can run more voltage if you want to. if you want some insane speeds kick it up a notch and run a 6s lipo. you would have to adjust your gearing though.
