Anyone use a Lithium battery for starter/accessories and AGM or Wet Cells for the TM?

[bman5150]

I'm considering adding a FFS to the bow of my boat. If I do so, I'll have a Lowrance Ghost 24v TM; two Lowrance Live 9'; and a Lowrance Live or Pro 12" with active target.

I currently run the Ghost off two wet cell batteries and would like to continue doing so since I never have any issues with running out of juice.

Is there an onboard charger than you can setup to run Lithium charging profiles for one bank and wet cell/AGM for the other two banks? My Ranger dealer said I can send my current Dual Pro charger to Dual Pro and they will switch out the one bank so it can charge a lithium battery.

Thank you - very cool. What amp level is recommended for Lithium batteries? My current Dual Pro is 15 amps x 3 banks. I know my current x2 31M starter/accessory battery does better over time when it sees 15 amps but wasn't sure if that's also how Lithium batteries worked.

15 is good with most. Your other Post about brand of lithium I think the only one certified with Merc is Relion.( They own Relion) That may have changed. Not sure on that.

10-20% of the rated capacity is pretty good for a LiFePO4 battery. Be sure you are looking at that chemistry of battery and not a 14.8v lithium NMC battery that some companies sell. That requires a unique battery charger.

I have this fairly budget priced 3-bank charger. It’s working out well. (ad) https://amzn.to/418ZML2

Have this exact setup currently. The Tracker (Relion) 100HP for the starting battery and all besides trolling motor. There are three heavy AGMs currently powering the Ghost. They are on their 5th season and still going pretty good. They will be replaced by lithiums and replaced the MK 460PC with the NOCO Genius.

I'm planning to replace my lead acid starting battery with lithium, but will retain the lead acid batteries for the TM. I'll use either a 5 or 10 amp NOCO.
