Lithium batteries

[biteme]

Thinking about making thr seap to one 36 volt 100ah and one 12 volt 100ah battery for cranking.

Those of you that changed, how do you like them? What was the cost? So far, I'm looking at 2500 from what I've found.

Thanks!

Lots of info on BBC about lithium batteries under the electrical/wiring/trolling motor topics. This one is an excellent read: https://www.bbcboards.net/showthread.php?t=982657

It depends on the application. For the average newer boat in the 20-21ft range I would go with 3 X 12V 100ah batteries for the TM and stay with a high-quality AGM for the cranking. You may need a charger depending on what you have. The cost is anywhere from $2200-3500.

Check out Dobyns Rods. Gary has some lithiums. Brand name is Gyll. They are 100ah. Last I checked they are less than 600 per with shipping. You have to call them because they are not on the website. I haven’t bought them yet but I do know a couple guys using them with no issues. When my lead acids go bad they will be my next purchase. Maybe Gary will see this and chime in on specifics.

I went with Impulse Lithium back in September and bought the 24v "all in" kit which included:

(1) 12v 125 ah cranking battery
(1) 24v 60 ah trolling motor battery
(1) single bank on-board charger
(1) charge-on-the-run converter that charges the 24v battery while the big motor is running

I paid $2273 for everything with no tax and free shipping after the BBC discount. Batteries came with a full 10 year warranty, non-prorated and have Bluetooth monitoring as well. So far they have been great - I run a 2018 Nitro Z19 with a two stroke Mercury Pro XS 200, Helix 12 MSI on the console, 2 Helix 9's with Mega 360 & Mega Live on the bow. After a full day fishing a club tournament, my batteries are around 65% and usually charge up to full in 3-4 hours.

You can get higher capacity batteries or do multiple smaller ones to get a little more juice, but this has worked well for me for the money spent!
