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.

Hello Jacek,
I am using the K2 type for two years now and can only report positive
about it. The capacity is absolutely sufficient to keep my radio,
vario and PDA going for two days while the weight is almost half of
the traditional sealed lead acid type in the identical frame. You will
have to buy their charger as well but supposedly one gets more cycles
out of this battery type than the SLA's.
