I then contacted Shorai as I had purchased the battery directly from them and they promptly sent me a new battery no charge. Good customer service. Anyway what I found interesting is that while they used to list the 18A1 as a battery option for the F8 on the Shorai website, now they list the LFX21A6-BS12. And this is the replacement battery they sent me. So far so good. But I am watching the voltmeter more closely. I sure as hell don't want to be out in the sticks and have it die and not take a jump.
I had the same experience minus the Death Valley experience. They sent me a new battery here in Alberta, no problem. Excellence customer service, and upgraded my battery to a newer mor powerful version as you did above. I have the Shorai balance charger and keep it on store over the winter. I thus far have had no issues.
