I've only begun to dabble in Lithium batteries, so I started with a Eco-Worthy 50ah & charger. My intention was to replace the series 29 lead acid battery I was using for my Livescope setup. I live in an apt complex and have to take & bring all batteries & removable equipment each trip, plus I live upstairs

I charged the battery & went fishing, and the battery quit after ~6hrs running the LS setup (Box + 93sv). I was expecting a longer run time, but then I remembered that the charge icon was flashing at the top, so it may not have been fully charged (maybe 80% - 90%). I've since charged the battery up until the charge icon is to the top & the charger is in maintenance mode. Problem is, I haven't been fishing since ... due to other problems.

Whether or not the battery will be sufficient or not remains to be seen.

But I am happy with the charger : 5A 12V Automatic Smart Battery Charger and Maintainer with LCD Display for Lead Acid and Lithium (LiFePO4) Batteries | ECO-WORTHY
My Minn-Kota 220 charged up the AGM & Lead Acid batteries (green lights on) ... then I hooked up the Eco-Worthy just to test it and it showed both batteries NOT 100% charged. The only "con" on the charger is that it's not supposed to be used "outdoors". But if I have to carry my 11lb Lithium battery indoors when I'm lodging at the lake, I'm not gonna complain.
