You do bring a bit of costing perspective into the argument here.

John,
that is really interesting. Have you sampled more than one battery or repeated
the test on the same battery?

I don't have any graphs or deep knowledge to back my decisions up, but
personally I have moved back to SLA.
In my glider I have used NiMH with some success, but the lifetime of the
batteries (9Ah D cells with solder tabs) was only 2 years, and very expensive..
I think you have to be a lot more

As I said yesterday, do proper engineering on your battery installation.
If you don't have real numbers for temperature limits, discharge
curves at various rates, charging characteristics etc etc you aren't
doing engineering, you're just guessing.

Hi Mike. Really glad you mentioned the quoted rate, I forgot to mention that,
as it is how I got better batteries in my glider - point being of course that
it doesn't matter if SLA, NiMH or Li* - you have to check those discharge
rates, and temperature curves. We recently sent equipment to

These batteries fit in a standard Schleicher, Schempp-Hirth, etc. battery mount.

Hello,
Has anyone located a source of K2 Energy Lithium Iron Phosphate
batteries in Australia? I have tried Googling but without any
convincing result and despite changing the search string.
The K2 Energy K2B12V10EB looks interesting as direct drop in replacement
for a standard 7 Ah 12V
in a glider trailer...
