I would not go as low as 7P with any cell on the Bomber or Fighter. Even with a cell 30Q cell capable of 20A+ you are then limited to ~20AH and will be stressing the cells with every 5KW launch. That battery will not have a very long life unless you limit power to less than 3-4KW.FL bomber said:36cm ×15.5 ×11.5 is the size to fit in the bomber? Em3ev said they could fit 21 s 7p with BMS.

Yup! I did this previously with some LiPo. As long as the wider sections clear the top/bottom lips, you can cram up to 135mm wide pack in there. I used some thick weather insulation padding around the side panels to buffer them out a bit. Works well.Theodore Voltaire said:I just got a brain storm. Why am I stressing about the width of the battery? I wouldn't care if it was 1 1/2" wider then the frame, if it fit the other dimensions. I could easily fabricate some kind of spacer to take up the gap. That should increase the possibility's I would think.

FL, I just went out and did some careful eyeballing using the dimensions of 36x15.5x11.5 cm you provided. Its going to be a real tight fit.
I think it will fill fit but you'll probably have to remove some or all of the rubber cushion on the back side, and about half of it on the bottom. Good luck. I give it a 85% chance of working.
Nah, 30Q cells are good for 15A and stock controller is 65A thats 9Amps per cell during launches. About 2/3 of their rated value. Almost vacation for them =)Cowardlyduck said:I would not go as low as 7P with any cell on the Bomber or Fighter.

I would suggest to everyone you want a minimum of 8P, or better 10P for any 18650 replacement pack for the Bomber or Fighter, even with super high C rate cells.

Hi-C battery they're out of Colorado and offer a one year warranty. They make 20s 72 volt 21 amp hour up to 42ah. Prices starting at 1249
FL bomber said:Hey Theodore I just got off the phone with Hi-C. They sound like they know what they're doing and prices seem reasonable. They're building packs from 30 Qs and vtc6 cells. Waiting on 20s 12p price quote.
FL bomber said:21s or 20s 12p for my bomber.
What are the pros and cons efficiency?heat buildup?
Power? With the 21s I can use the stealth Chargers I have. But the 21s I think we'll be to tight at 380cm
Versus the 20s at 360cm. Will the 20s still hit same speeds as stock bomber?
FL bomber said:What cells are in stealth new pack? How do they fit 22s? Must not be using 18650
