After wrecking a not-that-good sealed lead acid battery, I decided to try something more robust (and hopefully with a longer life) to handle my lighting needs on my '99 street legal TE610. After a lot of reading, it seemed that LFP (or LiFePO4) was the best way to go. The one negative seemed to be that over-charging and over-discharging would shorten the life of the cells, which meant a protection circuit was in order as cheap insurance... which also meant worries about vibration on the protection circuit, etc. The other negative is just how they work in really cold weather, but since the bike is a kick start it shouldn't affect things much.
Here's what I ended up with: 6.8Ah LiFePO4 setup in an aluminum enclosure, and an encapsulated / potted protection circuit. It's held up nicely thus far, and weighs a lot less than the 5.6Ah SLA the bike had before.
If the cells hold up to their advertised values, they should be good for 2000+ cycles from 80-100% which is far, far, far more than SLA boasts.
