Have been checking into LiFePO4 batteries. Was concerned about the Lithium ion "Tesla"effect in which everything within a 50 meter radius is suddenly incinerated. However, I found a Colorado company called Earth-X that assembles their batteries in the US. They have achieved FAA certification for use in aircraft, so that must amount to something. 2 year full replacement warranty. Even though $$$, I decided to bite the battery and order one. 

   Very small, and light, as expected. 13.65v as delivered. Took some cranking to blow the cobwebs out, but once it fired off, all was good. Definitely starts faster than the Yuasa AGM that was dying. And apparently, as the battery type has more cranking amps as it warms up(?)

   All new stuff to me, but anything that starts the V11 and lightens it up is OK with me.

I have 2 of those earthX batt’s now.  well, actually one, as a failed relay on my 1200 Duc killed one of them, barely out of the starting gate, with me returning to my bike i had stored down south to find the voltage at around 1.4V.  that story is told elsewhere, but a sure scientific sign that Murphy loves to have a laugh…. spend the big bucks, high-five for how great it seems to turn out, then an apparently known Duc (service bulletin, unbeknownst to me) issue kills it.  But the 1st one is in the V11 and I am indeed quite fond of it, for its small size and lovely cranking power. 

I’ve now inherited a 2nd “no name” li-ion battery, and so far so good, which is newer territory for me.  because of the aforementioned concerns with li-ions i’d been sticking with highly rated ones when i’m buying new, but i’ve got 2 cheap/no-name brand li-ions now in different bikes i purchased used, and they’ve been great.  in fact, a 3rd one, actually a big-name unit (brand escapes at the moment…) is from 2018, and its still going strong (in KTM 990, but removed it when i sold the bike), so thats a single data point for longevity. 

Doc, where’d you find a PC545 for $148?

That's a good trick. Probably won't save you if the battery is really knackered, or if the charging system is faulty, but will protect you from you own stupidity if you're prone to forgetting to turn off the lights when you park the bike.

Odyssey ODS-AGM15L ("PC545") arrived at 12.68v, just above the recommended 12.65v charge threshold.

Discharged with a 55 watt lamp to 12.18v and charged with 10 amps to 15.0v (only a few minutes).

Enersys Optimizer for two hours stabilized at 13.41v. Installed in mySport and discharged with lights to 12.40v.

Then 24 hours on the Enersys Optimizer to "bulk charge" and stabilize at 13.56v.

I'm calling this new battery "conditioned."
