wow, thats pretty nice! but what does the 20c stand for? that is 20 cells is it?

Well Im not sure I am waiting for more specs but the guy from BulldawgRC tells me its 2 cell and its inclosed in an aluminum case for protection. There is 2 cells in each box run in a parallel to make the ESC think its only running a 2 cell. He say's they fit perfect on axle plates on an AX-10.

Re: New Lipo Saddle Pack

nice!! get us the specs when they come in!! thats a nice find.

i am digging the protective case. wonder if that would effect the battery temp though?

BullDawg just sent me another link;

Once on the link, click on the left side on Trakpower 4800 Saddle Pack.
Man these are awsome, Im ordering mine. Hopefully it will be in for the Comp.

Re: New Lipo Saddle Pack

20C does not stand for 20 cells. 20C means the battery can discharge at a max rate of 20 times the capacity of the battery in amps safely .

SEE EDIT!!!! So for the batteries shown at 4800 mAh, that is 4.8 amps. 20 times 4.8 amps is 96 amps peak discharge rate. See EDIT!!!!

This is WAY more than a 2.2 with a standard 540 motor or a brushed motor will need in a crawler. A lipo with around 15C is plenty.

EDIT: Those are 2S2P packs for 4800 mAh. This means 2x 2S 2400 mAh packs wired in parallel. Max rate is actually 25*2.4 which is 60 Amps.


NOTE: While most batteries can handle discharging at the max rate it is not recommended that you use this for a continous discharge rate.


While those batteries look very nice, I am not so sure I would drop the coin on only a 2 cell lipo. A 2S lipo ( 2 Cell series wired) is 7.4V and a standard 6 cell sub-c pack is 7.2V. You are only seeing a weight savings, and a more linear discharg of the battery. For someone like you Rockbound it may work as a 2S (2 cell series) lipo battery is within the limits of your ESC. Don't forget to set the lipo cutoff, get a balance and lipo compatible charger.

As most know I am power hungry and in a comp rig will not run anything less than a 25C 3S lipo .

So Busted do you think it will be a good batt for the AX-10

Re: New Lipo Saddle Pack

It depends on the motor you are running. If you have cowbell then nothing less than 20C. If you are running a 55T or more you could get away with 15C.

Just think of it as a pipe. The bigger the pipe the more sheat will go through and faster. But if you don't have enough to push through it will trickle...

What motor are you running along with what ESC do you have?

Most ESCs, other than the MM and I *think* the sidewinder have a 2S lipo limit.

If you are running a normal 540 motor or a brushless outrunner than you will be fine. If you are running a Cobalt puller, you would be ok with that discharge rate, but it will not be happy at that low of a voltage.


Why not run the MaxAmps saddle pack? Its cheaper and comes in compareable mAh ratings? Now the C rating is lower but you dont need 25C in a crawler unless you are running a puller motor.

Depends on the material, but yes it will cause the battery to run a pinch warmer.
