    As I have the xp-3, this pigtail is now on my radar to be purchased in the near future. Thanks for the link/heads up

    Normal SAE connectors and wiring are NOT large enough for the amps needed for a jump start. That is why the jump cables on all these jump packs are big... and short.

    In response to the original poster's question about running the bike off of a Zero Gravity (or other lithium starter battery), the Zero Gravity manual that came with mine says to disconnect the starter right after the engine starts ( I think they mention something like 30 seconds). Lithium batteries are generally charged through a battery management system and getting 12-14 volts straight from the charging system is likely to cause overheating and damage.

    That's absolutely correct sir.

    I am not sure I agree. Both the clamp assembly and the direct to battery harness contain a diode which shows continuity from the battery pack to the bike but not from the bike back the other way.

    You're correct, I saw that 30 second warning on their website today.

    Disconnect the starter . Does that mean “release the starter button”?........or git your wrench out?......unhook the jump pack?

    I purchased an Antigravity XP-1 in May 2016.
    It stayed in my car except while moto-camping on about 15 trips over 2 years time.
    At first I liked having the convenience of it as a back up, just in case.
    It was used twice to jumpstart cars and a dozen or so times to charge a cell phone.

    Then this happened

    As far as the phone charging aspect, about half of the campsites did not have cell service (phone turned off) some of the others would have 110V outlets to use or the bikes battery could charge it. (the phone)
    The XP-1 took longer to recharge after charging a phone it than it would take to charge the phone on 110V.
    It is a convenience I rode without for 49 out of 51 years, do not miss it, so it will not be replaced.
    One use that it works well on is a EFI bike with a low voltage battery and a good charging system.(enough juice to turn the engine, not enough to fire the injectors)

    My jump box from cycle gear did that about a day after warranty ended.
    One thing to beware of several years ago I was looking online for Anti Gravity jump box and there were a bunch of counterfeit ones.

    I've seen enough posts warning about counterfeit Anti Gravity so I purchased mine direct from Anti Gravity.
    Same thing with the GS911, there are a lot of fakes.

    Did you purchase it from Anti Gravity.
    Did you contact Anti Gravity about the failure?

    Here's what a XP-1 looks like on the Anti Gravity site.

    I bought one of these over a year ago. It looks like it came from the same factory as the Antigravity. I have used it several times and am very pleased. I have jump started my lawn tractor several times recently and it still shows 100%. I use it mostly on motorcycle travels as a cell phone charger when power is not available. Haven't had the pleasure yet of starting a dead bike but have no doubt it will do it.
