Battery Ideas for New Dragonfly 6
 

I did a self-test with a rechargeable LifePO4 battery. The battery is advertised as "12V-10Ah-128Wh," and is lithium ion. Fully charged, I plugged it in and left it on simulator. It lasted only 9.5 hours. I need a battery that is going to give as much time on the water as I wish, yet maintain a small foot-print. Any Ideas and suggestions would be greatly appreciated. I can still return the battery.
