In a deep cycle application such as providing backup power to systems after

service at a steady voltage than any lead-acid chemistry and at about of
the 50% weight per AH and for about quadruple the discharge cycles. There

Jeff thank you this has long been my position. The steady state delivery
after a dynamo goes down also biases me to SLA...

I spent years as an engineer in Industrial Lithium Ion technology. Mostly
BMS like Lithium system charging design and such. I actually even own an EV
and its really cool but its just not prime time and I never see it go
there.
As loud as I can type it, I would never ever fly using a LIthium Ion

Sorry about the "3 posts". They appeared to not be going through and I
kept re sending. It was like the duck with the hammer and the caption
says "hit any key to continue".

By the way, Mark, I have the newer Great Plains 35 amp alternator. Not
that I needed it, but I dropped my magnet ring the last time I had the
engine apart, and cracked a magnet. The original 20 amp magnet rings
are no longer available.

that the bms is defective (not likely). Your over drawing current past the

Hi Mark. I am using an Odyssey Battery, in my KR. A battery that shuts
itself off, is not for me or my KR, electronic ignition or not .John

I'm by no means an expert but does your "dynamo / alternator/
whatever" need to see battery voltage to have an output? If so and
the battery shuts off, poof !!

Your alternator or dynamo system should not produce power without the battery to excite the system, so if the BMS system in your LiFePo battery is shutting it off, then your system goes dead. EarthX doesn't seem to have this issues, but using an AGM battery is a solid and reliable fix.
