Folks,

The last few times i have gone out to fly, my EarthX 900 battery has cut completely out during the starting sequence. Wait two minutes and it comes back for another try. With a pre-heated engine and spun the prop by hand a couple of times before the start sequence to make sure there is no hydraulic lock.

Fully charged and tests passed with the EarthX charger.

My first thoughts are not the battery's fault and I have sent EarthX a note with questions. Next, I am thinking about loosening and re-tightening all of my starter related electrical connections.

Less than 400 hours on the engine and starter - about 100 hours on the battery.

Thoughts please!

Ralph,


At what temperature are you attempting your first start.


It is my understanding that the LI-ion batteries, when very cold don't have much oomph, however hitting the starter for a second or two warms them up, internally, and they function normally. Perhaps this is what is happening to you.

EarthX did respond about colder temperatures but did not make a recommendation as to warming the battery with this type of draw.

I run the fuel pump as part of the starting sequence - maybe I'll try more load and then shut off the loads to crank.

Thanks for the responses.
