It's a kLOT easier to make a couple of say, 8" diameter or so plates VERY thick to withstand the structural forces than it is to make a flat rectangular plate which, as someone pointed out, will have uneven forces at it's center. With the two flat ends, if you employ a sort of "floating" O ring approach then there won't be much force transmitted to the cylinder either. Even without this floating approach, you're still taking about a much better design than the neutraleak approach. Theoretically you could make the walls of the neutraleak strong enough so, for practical purposes, it wouldn't be an issue either, BUT, Dive Rite actually designed the walls to use the batteries as a structural member. That says something about the strength of the entire container. As Ken pointed out, sometimes this results in battery failure (in the case Ken was pointing out, fairly catastrophic failure too!). -Carl-
