    I don't know how many other brands have this, but it doesn't matter if regular EarthX batteries are completely discharged (lights on, parasitic draw, etc.). It just needs to have the BMS reset and then charged normally. They won't actually go dead and be harmed. It removes some worry with an expensive battery. That was a nice feature on my 640 that did have a small parasitic draw.

    The ETZ model I bought for my 525 doesn't have that feature and is significantly less money. But my entire electrical system is on the relay side of a Trailtech stator. I literally can't leave anything on. The whole electrical system shuts down thirty seconds after the engine is off. I have an accessory plug directly connected to the battery in case I ever need battery power with the engine off.

    Being a forgetful old(er) man, I try to idiotproof my batteries.

    Are they good, bad or a rip off?

    Their prices seem real good.

    Anybody have any thoughts or firsthand experience?

    So my earthx battery gave up the ghost and I had a very positive experience so thought I’d share (although to be clear I’d have shared if it was bad too). Initially I’d opted for earthx over antigravity and shorai because their warranty is a full two year warranty, not prorated over time of ownership.

    Anyway, I filled out the warranty thing on their website and got an email with a question (how long the battery had sat) within ten minutes. Replied and then got another email an hour later saying they were shipping me a new battery and three days later here it is. This is exactly how I think a warranty should work so I’m pretty happy about it and thought I’d share. Obviously YMMV as in all things, but I like to think we should encourage good behavior by companies by sharing good and bad experiences alike and giving them feedback.

    How old was your battery?

    14 months.

    e: I bought it 14 months ago. I don't know the manufacture date if that's what you're asking.

    Thanks, not too encouraging.

    Because of the time it took the battery to die? I don’t disagree that it should have lasted a lot longer, but I think you also have to take it with a grain of salt just because you’re not seeing a ton of folks postin the same, you have the common internet confirmation bias of people only ever posting about problems and last but not least they’re apparently actually putting their money where their mouth is with a two year warranty that was, in my experience at least, ridiculously fast and easy. Maybe I’m just still pleased because I’ve never had a battery problem where the solution was “no worries, we’ll just priority mail you a new one. It’ll be there in three days.”

    Anyway, we’ll see how the new one goes and I’ll certainly post about it if it dies too.

    My Yuasa YTZ14S started to die last fall after 5 years.
    Trickle charged out of the bike off season.
    Battery Tender Plus was used.

    Ohboy, tires, battery, and maybe chain and sprockets needed for the spring.
    Get ready to ride!

    You sure read an awful lot into my four measly words! I'm actually running a Scorpion LiFePO4 battery in my super tenere. I've only got a few months experience but so far so good and it cranks a lot more vigorously than the OEM Yuasa YTZ12S ever did which seems just barely adequate. The Scorpion also has a 2-year replacement and a 3rd year prorated warranty.

    I think that was code for "I was at least counting on a handy, but hoping for a BJ as extra recompense for the short battery life".

    Can a LiFePo4 be recovered from dead flat with a regular L/A charger? I have a Shorai on my Dakar and was planning to ride occasionally through the winter, but with the actual winter weather this year didn't and forgot about it being hooked up. Will I damage it by trying?

    Did you try it? If you don’t have parasitic drain, it should have retained its charge (a benefit of LiFePO batteries). If you do have some drain it’s probably dead-dead.

    Yeah, there's an LCD clock and it is not being powered anymore. Any point in trying anything on it?

    If you look back through this thread, I think there is a method of using a different, charged battery to fake the charger into working and recharging the dead battery.

    So I shouldn't be charging this booster pack then?

    I didn't even take that into my house, let alone charge it.
    I left it in the BBQ until it had cooled, then took it to be recycled.

    Was this a LiIon or a LiFePo4 cell?

    I'm pretty sure it was LiFePo4.
