B4 Lipo fitment

[sosidge]

I wonder what some of you are doing to get the slightly larger BRCA-legal LiPo packs into the B4 neatly?

I've finally switched to LiPo with an Intellect 5000mAh pack (same pack as many other brands).

Unfortunately this pack is just a tiny bit tall to fit under the rear shock tower - probably a mm or less in it, but just enough to stop the cells from going all the way back and to stop the carbon strap from fitting properly.

So what mods are you doing?

I've narrowed the options down to...

1) Grind the locating bumps down (which I don't want to do)
2) Trim the rear shock tower (wary of weakening it)
3) Change the strap to an extra thin one (needs to be 0.5mm by my reckoning which is too thin to be effective!); cut down the existing strap so it only braces the front of the cells; or lay the rear of the strap across the top of the tower
4) Something else?

Changing the LiPo is not an option.

I can see how the LRP-style packs work so well, if I flip the Intellect pack it fits perfectly under the strap, only problem is there is no easy way of unplugging it!
