When Nicads came into the picture no roboteers were forced to go to nicads, if they wanted to stay on SLA that was fine.

When NiMh became more interesting for feathers, no one forced roboteers to go to them, if you wanted to stay on Nicads or SLA thats fine.

No one is forcing anyone to go to A123 cells, if you want to stay on NiMh, Nicad, or SLA, that is fine. But do give the roboteers that do want to use them the chance to do so.

Decisions on the investment of batteries, packs, chargers, balancers should be up to the roboteers, in the end they are the one that will have to care for their investment. Those that want to invest in this should be allowed to do so.
