Thanks charlieN. Any risk of damage to my 8 amp B&C alternator?
No, no risk.
What the issue is with high power batteries this small is the inrush of a 60+Amp alternator will smoke the tiny cells in these packs, especially the ones utilizing 3 high output cells. The Earth X has a better tolerance to this. The solid magnet 8A alternator you have, as long as it is regulated well should be no issue to these batteries.
You do want a modern gear reduction starter on your plane, they draw in the 80-100ish amp range where the old big iron starters could need 250-300A to spin them.
My experience over the past decade around race cars with Anti Gravity and Ballistic batteries is a stupid high failure rate, as in I have seen one battery
not fail. These batteries did not have discharge limiters nor good cell balancing. The Anti Gravity Micro start batteries have failures due to these issues.
I have seen failures on more than one day old battery.
The motorcycle guys I know are experiencing a high failure rate in the Micro Start with cell failures.
A scare I had just a few weeks ago, I went out to my old 1972 Kubota, plugged in my Earth X, this old tractor need to run the glow plugs for quite some time compared to new diesels. When I motorized the starter I just got a clunk, second try not even a clunk. The jump pack was more than just warm.
Went inside and plugged it into the charger, didn't even get one light on for quite some time. A few hours later, it is back to life as if I didn't try to F it up by running it all the way down.
What I have learned tha past few years with this technology change, buy devices that utilize LiFePo4 cells which is what EarthX uses. They are less powerful per cell than other batteries especially those with the unstable LiCoO2 cells that had a bad ride in the news with the 787 and some flaming cell phones.
