Batteries expiring after one year and 50 or so cycles?

[boss]

Have had two 36V, 10 a/h batteries basically expire precipitously after one year and 50 or so cycles. Everyone marvels at the low cost of recharging a battery, but this equates to $8.00 or so per outing. My 52V Luna battery is still potent after a year, but they're just a reseller and it may be hit or miss with them too. What's your experience?

They claim around 600 hrs on my Turbo S. I'm not close to it yet! Probably lose track when it does take a dump.

Probably I got about 100 hours on each of mine; extremely deficient. Avoid Headway batteries. IMO, for DIY batteries, it's either Luna or em3ev.
