That is pretty massive. I know I have to pull that up a bit to fit in 2 of the SMC 2S 7400's as well.
Thanks for the pics. I have been trying to decide between two 3s packs or one 6s pack. It does seem like you save space/size with the one 6s, due to not needing 2 cases.
Also I was thinking the 7400mAh would be a but too big/heavy. Thoughts?
Edit: Looking at the SPC site, here are the following weights for the 6s packs:
4500mAh = 594gr /20.95oz ($80.95)
5400mAh = 805gr /28.4oz ($94.95)
7200mAh = 904gr /31.88oz ($124.95)
7400mAh = 976gr /40.56oz ($124.95)
That seems to be a rather large jump in weight between the 4500 and 5400. I am guessing the inclusion on the G10 plates are accounting for some of the extra weight.
I am leaning towards the 4500mAh I think. Just not sure the extra 900mAh are worth the extra weight.

The 7400 is a big battery! However, I like long runtimes. I'm not terribly brutal on my stuff so it should be fine. The outcast is 1/8th scale and trucks this size are typically heavier than their 1/10 scale counterparts. I'm sure the power to weight ratio is in favor on the power side especially on 6s. They say here on the forum it's a different truck on 6s so we'll see. I'm thinking I will tune out some power with the esc to save the diffs just as a precautionary measure.

2.5 pounds?! Wow!
When going from 4500 to 5400, the extra weight could be because it uses 2 cells in parallel vs a single cell. It appears the 4500 is 3S1P whereas the 5400 is 3S2P. That's how all my 2S packs from SMC are, the 7200/7400/9000 are all 2S2P. So, to get to the higher capacity, instead of using larger cells, he's doubling up smaller ones. Probably how they keep the cost down and quality/performance up on the higher capacity packs.

Yeah series parallel wiring. As long as all cells balance then we are good. Can't wait to take it out on 6s to see what it can do. Next I have to tune down the esc a smidge. I have gone through the diffs and shimmed them internally and shimmed the ring and pinion side. Diffs should hold up. Fingers crossed
