They don't have anything to do with each other, but I'm going to tell you a story. Hopefully some knowledge in here will help if you are having these problems.
I have a friend with an 09 K-9. He doesn't ride a whole lot, but gets out when he can. 3 years ago, he replaced the battery with a Harley Deka battery. Most of the time, we get 6 to 7 years out of these batteries. We do not keep these batteries on a tender. In the winter time, we throw them on the charger once a month, and any other time, if it's been a couple weeks since we've been out, we'll top off the charge before we go.
This is what these lithium jump boxes will do, and I'm going to include those high cranking amp batteries too. Even though I haven't use any. Last fall, for some reason, his battery went completely dead. Instead of charging the battery, he hooked up his jump box and blew the start circuit out of his original EHC. So we replaced it with the Axle unit, and charged the battery. All worked fine the rest of the year.
We did a bit of work to it over the winter, and I noticed the battery was not cranking the bike like it should, even though it showed 13.8 volts. A clear sign that the battery was beginning to have a shorted cell. And told him to replace it. (more than once, like 5 or 6 times)
We went for a ride several weeks ago, and his bike started at the house, because it was on the charger, but failed to start at the gas station. Out comes the jump box. After several tries, it starts. We ride an hour away for lunch. Bike won't start. Out comes the jump box. After several tries, the bike spins over but wouldn't fire.
I cannot make any connection between the jump box and what happen next. It may just happen to be plain coincidence. I can see the light on the ignition module. It was getting power, but no signal. After a few more ties, it fired, ran for about 3 minutes and died. Trailered home, replace the battery. Fired right up and ran fine. For 3 miles. Same thing, power to the ignition module, but no signal. Back to the shop, pulled crank sensor, and it tested ok. Checked all the wiring with a meter, all good. So we figured that jump box fried part of the ignition module. Replaced ignition mod, and the short wire between it and the crank sensor, that we tested for the umpteenth time.
Fired right up, ran for a good 5 minutes in the shop, but 2 miles down the rode, we were loading it back in the trailer.
Turned out to be the crank sensor. Even heating it up with a heat gun, it still tested good.
Put almost a hundred miles on it tonight. All is good.
