Hi,

I just added some new batteries to my web site tonight. They have been
highly recommended to me by several sailplane pilots.

New - Bioenno Power Lithium Iron Phosphate LiFePO4 12V Glider Batteries

- Enhanced cycle life - up to 2000 charge cycles! After 2000 charge cycles,
the battery still holds 75-80% of its original capacity.
- Lower weight - less than half the weight of lead-acid batteries! If you
are accustomed to using lead-acid batteries - you will be shocked the first
time you pick-up one of these batteries.
- Constant and stable discharge voltage - Lead-acid batteries gradually lose
voltage over time as they discharge - dropping below 12V early-on. LiFePO4
batteries have a much more gradual decrease in voltage until they are nearly
fully discharged - staying at 13+V for most of their discharge cycle - so
they are able to power your sailplane radio and instruments at higher
voltages for longer periods of time. Higher voltages assure maximum transmit
power from radios and transponders.
