Hi,

I got a Fusion LiFePo4 battery. It's the size of a small brick but less than 2kg. It's rated for 15AH at 12 volts or 192WH. Powers heater straps, usb hub, camera, focuser all night long. Just a bit expensive.

Outputs constant 12volts all the way down, though I wouldn't run it below 20%.

Cheers
Paul
