A friend has Humminbird Helix + Mega Live running on an AMPED 18ah lithium, but I don't think he's used it for an ALLL day trip yet. I wouldn't buy any cheap off brand Amazon lithium, personally.

 

Thanks ya that's the same unit I'm running. Regarding the Amazon battery, ya that's why I'm wanting some options, so thanks.

So I just set up my ice system this year with a garmin and I have a homemade battery box with 2 amped outdoors 13 amp hour batteries and I went out every day this weekend thinking that after 8 hours or 9 hours I have the batteries pretty run down and put them on the charger and they were reading that I only drained them down to half power. So I would definitely recommend amped outdoors and the charger I use for them is a noco 10 amp single bank charger.

 

For Livescope, I'd go with the Amped 30AH with their charger.

 

i run an HDS live 9 and an active target 1 with an Amped Outdoors 32 amp hour lithium battery and get between 10-12 run time

 

I'm using the same battery I use in my boat a Marcum Lif PO4 Lithium 12 volt 18AH battery which comes with it's own charger. Lithium batteries require their own specific charger. I run a Helix 9 and the mega live off this battery and it works great.

 

I just checked And it’s an AMPED 30ah, not 18ah, that my buddy runs his Mega live with

 

Well after considering all the responses and doing some more research, I actually settled on a 36AH Weize battery and a Noco Genesis 5 battery charger.
Thanks for the replies.
