Thread: Lithium Battery Question

On 4 for 10 hours you wont even draw a 50ah down past 70-80% remaining. I know because i run them trolling for crappies/walleye. Also on 4 im going almost 2mph with lithium, used to be hardly over 0.8-1.2mph with lead acids.

If you are running on 3-4 now, youll be 1.5-2 setting with lithiums im sure, hardly drawing more than an amp.

You absolutely do not need a 100 or 125ah IMO.

I suppose i should say why so little battery usage. It is because lithium does not lose voltage as the charge decreases, it runs at 13-13.2 constantly instead of 10.8-12.4 with lead acid. Higher voltage means less amp draw for the same power, your power draw numbers are probably based on 12.0v.

I thought i would be too small with 50ah on mk 80lb, but I have never been lower than 80% remaining at the end of one day.. my typical use crappie fishing for 6-8 hours is around 93% remaining. On trips, i usually dont have to charge until the 4th or 5th day. I actually got a few comments last year about not charging my boat while others have extension cords everywhere. "Have you even charged your boat this week?" "Not yet, still at 65%" and their jaws drop.

I am so glad I bought ionics with Bluetooth for this reason.

Are you running one 24 volt or two 12 volt batteries?

I am using two 12v because I wanted to use my noco gen5 onboard charger.

I use two 12v 50ah ionic. You can use one 24v 50ah if you want, there is no noticeable difference. I was simply not confident in the 24v chargers available, and wanted to use my noco onboard.

Only problem with 24 versus 2 12 volts is if the battery locks out any 12 volt source will get you up and running again, not so easy finding a 24 volt source while out on the lake.

Yep that would definitely be a problem. lol
