Jacek,

I'm using a stack of 2x4 A123 cells. It has 4,6 Ah and weighs only 700g.
Its volume is a bit smaller than the standard 7 Ah lead battery. By
buying single cells, you can build your battery in the shape you need it
and fit it to any unused space in your ship.

Hi there,

Does anyone of you have any experience with LiFePO4 batteries in
sailplanes? I need to up my battery capacity, but have very limited
space in my ship. I read about them a bit, but ..... So, here are my
questions: is it worth buying this type of battery (they are quite
pricey), is the size comparable to sealed acid batteries (capacity to
size), any issues related to charging. Your input would be greatly
appreciated.
