the only problem i found with SLAs, is that if you go very large, you may end up having to build your robot around your batteries! And then if you do ever upgrade you have this HUGE space of nothing, and i personaly hate thatm, i live likkle sweet compactor bots, lol.

Oh and by the way, how can you find out from any normal shop what discharge rate batteries have, because the shops by me know f**k all, they cant tell the difference between NiCads and Ni-Mhs lol
