I know the Rhino 1750mah is a pretty good fit, I think the Flightmax 1800 is abit too long.

The stock batt for the revo is 94mm x 34mm x 17mm............this 2200 Zippy flightmax is 100 x 34 x 17, can you find 3mm on each end of the tray to cover the 6mm difference?

I'm running those 2200mah 2s zippys - two in parallel. They fit, but you'll need to widen the hole in the battery door to route the wires through.

Do you have the brushed revo or brushless..........you can run two 3s in parallel in the brushless.

Hey,

I haven't timed the run times with these and I've only run my MERV through one charge so far. The weather's been pretty crummy, and the one pack I did drive it, I drove it straight into construction mud and made a good mess lol. Took forever to wash the mud off everything...no more mud driving so i'll wait till the weather clears up.

I would guess I got around 20 minutes of outside runtime....but I had also been running it on and off for a good while in the basement.

But I'd say you could easily get half an hour out of this setup. Likely into 40 minutes.

Yes, it is the brushless version. I could go 3S....but I'm really quite happy with the speed I get out of 2S. Suits me fine for zipping off the driveway into the empty lot next to us and ripping it up in there, then off into the street for a speed run, and then back into the lawn

EDIT: Those hobbycity lipos are stupid cheap. I think the 2s 2200mah ones i ordered were 8.79$ a piece. I ordered 4 of them.

wow, those look like a tight fit! How could you get a 3s in there?

If you look through the comments on these two, a couple people have gotten them to fit (albeit, very tightly)

Is it better to have the 30C batteries rather than the 20C? I am looking at either the Flightmaxx 2200 2s1P 20C or 30C versions. I see in the comments/reviews that both are capable of fitting. Does the battery fit too tight, is there danger of puncture or tearing the cell open?

Basically, the following batts are claimed to fit, the 20, 25, and 30c. Which would be the wiser choice?

To fully cover your butt, the 30C would be best because that battery can sustain higher rates of discharge over the other two options. But it really depends on what kind of amp draw the 1/16 has and I have no idea what that number is.

For example, a 30C (continuous) 2200mah could be discharged at 30 * 2.200A = 66Amps continuously whereas the 20C 2200mah would have a continuous discharge of 44Amps.

So the point is, it depends on the continuous running current draw of the vehicle. I would guess you would want to spec the battery to that, but maybe make sure that the battery's peak discharge could handle almost the stall current of the system? I'm not sure on that part...hopefully somebody else can chime in on this...

Though with the stock electrics and motor, I would think the 20C 2200mah 2s1p zippy flightmax would run fine unless you decide to lock all the wheels and give it full throttle or do something silly like that...

Just my thoughts

Just going to be running throught the street, snow, mud, gravel, etc... No racing just bashing. The difference in price is so little that I would get the larger C to cover my behind but if the fit is too tight, or dangerously tight, I'd stick with the smaller C battery.

Mera'din, i still dont see where you have told us if it is the brushed or brushless version. However, both should be fine with the 2200 20c putting out 44 amps continuous. The brushless motor in the revo shouldnt draw more than 40 at the very most.

I don't have one yet but I will be getting the brushless. I was just wondering what batteries to get. I usually apply the bigger is better approach to batteries. having the higher C rating in my planes gets me a longer lasting battery but the size of the 25 and 30 C batteries worry me in this car.

If I went with a 30 C batt it looks like the fit would be pretty tight and not allow any air to flow. But, with a higher C battery it shouldn't get as hot as a 20 C battery would. If the 20C batts are a squeeze then I definately don't want to force a 30C battery in there.

I think I may be overthinking things quite a bit. basically I am looking foe someone to straight out tell me which battery would be the best for this truck. Since I have no truck and no batts to test fit I turn to you!
