Default 4s lipo's

Any one know of some small high c rating ones. I have a few, but none fit on the skid aswell as I would like. Here are my requirements, 35 amp continuous discharge rate, no larger then 75mmx45mmx30mm. What fits?

35a continous is gonna kill you in that footprint. I would say the 1300's that I carry could be used in 4s, depending on the motor.

We could do a 30C 4S 2000 at 69mm X 45mm X 36 mm tall. That's 60 amps constant.

I thought about that JRH, it is going to be used with 2 30t handwounds. What is the minimum continuous amp rating I could get away with?

Im assuming this is a custom pack? I did not see it on the site. Can you pm me pricing info and turn-around time please?

Yeah I'm not sure why we don't have it listed on the site. I'll have it added in in the morning. As far as price it would be the same cost as two 2S packs. we don't charge for custom work. Some place around 120 bucks.

two 30t would really be pushing the 1300 cells hard, especially on 4s. Really hard. You have any other place to mount them? Something with a longer profile in a 2200 would be better suited.

Two 30t motors on 4s? Are you trying to jump the entire course? Do you have some special gears and dogbones we don't know about? I have a Holmes 30t on 3s in my Rock Force and it's ballistic, but the RF drivetrain is beefy enough to handle it. I'm not so sure about the berg.

I'm running a 3s 2170mah Flightpower on the skid of my 4.0 and it just squeezes between the links without limiting travel. . It would be a really tight fit with your Mambas. You could probably get away with it if you were running FX-R pros. The Maxamps pack is a good length, but the height and width won't clear the upper links.

I run Hyperion 23c 1440mah 2s pack (2 in series) I run them on 55t motors. On 45t it was just to fast on 4s.

the maxamps pack should clear in width and length just not height at the moment

Yeah, that's what I was getting at. The upper links stop ya.

If you do manage to get everything to fit, don't forget to put pics in your build thread. And a video!

No way you can fit a longer 2200 somewhere, like on the back axle?

I fit one of Holmes 2200 PolyRC 4s packs inbetween the front links on my 4.0. The rear of the pack lays on the skid and the front is strapped to the front upper links. You have to run almost parrallel uppers to keep it from binding while articulating

On 35t warrior IIs, it makes the berg inners fail on command.
