My 2 c.If it is indeed the bms shutting the battery off, it may be possible
that the bms is defective (not likely). Your over drawing current past the
capacity that the bms will allow, or it's overheating and causing it to shut
off. Also there may be enough noise on the charging circuit which causes the
bms to spaz out. None of this explains why the ignition system shutdown. Which
begs the question is it really the battery? Until you monitor the voltage at
various places and the total current draw your just kind of guessing. You need
the data.The good point in all of this is that your "dynamo" may not be working
as intended and now is a good time to verify it also.Good luck

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 Shaffer 455JS

Subject: KRnet> Lipo Battery
Yesterday I was doing a taxi test and had thefollowing happen more than once.
This scares me enough that I amnow very hesitant to use a Lipo with BMS.After
about five minutes of taxi, my engine shut off as if theignition switch had
been shut off. There was absolutely no power atthe ignition switch. The BMS
took over and shut the system down.After about 10 minutes, The battery came
back to life and shestarted right up. Only to again shut down after a few
minutes ofrunning. Why is this happening? Is it due to the Dynamo? Whywouldn't
my engine keep running just off the Dynamo. Does theBMS somehow disable the
entire system? I am feeling likeLarry Flesner said. I think I too will only
fly with AGM batteries.Seems this BMS in Lipo batteries is a source of failure
we do notneed.
