TIGHT CELLS

[bald eagle]

Hi all,
Just recently got myself a B4, I usually race touring cars, so I have alot of radio kit etc to go in the B4. Now then, I have just shoe horned a pack of miy ib 4200 cels into the battery 'bay' and they are soooooo tight in there its silly.! Does eveyone else have this prob, or have i just got an excess of solder on my cells? Any advice/help on this matter is greatly appreciated. Cheers in advance.. the bald one.
