will the maxamps 10k 7.4 pack fit? looking for extreme runtime

car has a dirt oval late model body so clearance isnt the issue

thanks

i honestly don't think it'll fit without making your own battery strap. i have a maxamp 6k 2s pack in my b4 with a 17.5 i get 45 minutes of hard driving before i hit lipo cut off

Dont know about a 10k but i had a 7.4 6k maxamps and i got 30+ mins of runtime

The 10,000 mah will not fit. It is much too long at 158mm to fit into the battery slot. Go with the 8000mah instead. At 138mm in length, it just fits in there. Plenty of run time and power and all you have to do is use longer mounting bolts.

Like nitrotruckn said, the Maxamps 8000Mah will fit, not the 1/8th scale pack, but the regular 8000 pack. Its a little taller than a standard lipo pack, but you can run longer screws through the battery strap to make it work. I have my B4/T4 set-up for long runs using this battery.

Thanks for the information...!!

I'll go with a 8k pack then.

maybe the 10,000mah will fit with the longer T4 chassis installed on your B4?

the 10k cells are also to wide. the 8000mah pack can fit with out much effort.

Flightpower 4900 20c soft packs will fit as well, just eliminate the foam spacer and it will be fine. I assume the 5000 25c flightpower packs will work as well

If you have a esc and motor that can handle it, a 3 cell will give you more runtime since more volts reduce the amp draw. Just would need to drop a few pinions so as to not have an overly insane speed.

Not much though, the 3 cell battery in the same space as a 2 cell will have to be made with smaller lower capacity cells. So while the amp draw does go down, there are also fewer amp hours available. A slight increase from an increase in efficiency, but not all that much I suspect. Possibly less runtime with the same motor even geared down, as it would accelerate harder. A milder motor would need to be used to take best advantage of 3 cells for runtime with a given performance level.
