    Lithium jump starters 3l

    Looking at these to carry in the truck and boat seems like the companies all rate these differently. Will any of them work to jump start a 250xs..lm looking at the noco gb70 and the weego n44..thanks

    Maybe, it would depend on the condition of the dead battery.....in my boat I would just jumper cable off of one, or more, of the 3 trolling motor batteries.
    Don't take others for granted, show appreciation.

    As stated, would depend on the state of discharge of the cranking battery, the cleanliness of your jump-starter's connection to that battery, and the rating/charge-state of the jump starter.

    As a general rule, it is ALWAYS best to have an amply-rated, fully charged CRANKING battery connected. There are inherent risks when you attempt to jump start (generally caused by human error- even if just for a split second).

    All of the above being said- we all know that if you're 20 miles down the river, and your engine won't start, you're going to do what you have to and head home.

    Thanks for replies, yes i do have a good cranking battery.just always worry when fish a long time in one spot with live wells , graphs, power poles working the cranking battery wont have enougb at the end of the day..my cramking battery is an agm and thats a lil of a concern to me jumping it off a lithium...
    The noco chargers are supposedly idiot proof as far as the connections are concerned and its also something i could carry in the truck..the noco 70 is rated at 2000 peak amps 15700 joules,but thats not cranking amps.they say they dont rate c.c.a. s..again thanks for all replies..

    Bought a NOCO GB70 for my boat. I haven't needed it for my boat yet, but I can tell you it jumped my Nissan Titan without issue when all I was getting was a clicking noise form the ignition one morning last week. Supposedly impossible to any damage with this model. If hooked up backwards nothing happens. Will not spark (according to NOCO) ever, even if leads are hooked up backwards or touch each other.

    Have you contacted Danny @ Stealth? He has a jump start kit that will work with the 12v Lithium Pro connections.
