The 36V NiMH battery pack on the WE bike is nearing its end so I am looking into a replacement. Before just signing up for another pack I thought I'd try to do something more elegant. Previously I asked about better battery storage and received numerous helpful tips here. Now what I'm wondering is there a battery pack in a plastic shell like the ones that come with the LashOut or BionX that would work with a generic motor and controller? The BionX is great, but I think there is some complicated interaction between the batteries and the other components that would make it unsuitable. The LashOut is out because it is only 24V and I find SLA unacceptably heavy.
What I'm looking for is something more rugged and more water resistant than the typical brick-o-batteries in a bag. Also I dislike the charging port and the switch dangling on the end of their wires. I have already lost one battery pack to this configuration. (Oddly enough it was fused, but the 15A fuse didn't pop. Eventually one of the legs of the fuse melted off after it was too late.) I figure one of the bikes that come with nicely packaged 36V batteries would be ideal. I just don't know which one. I don't mind doing some minor fabrication to get it attached to the bike.
