So I am in the process of repowering my marquesa, adding a little weight on the back end so Id like to shed it else where. My TM batteries (24v) live in my console and are reaching the end of their life span so im looking at a 24v lithium but all the brands out there make it hard to narrow down. SO does anyone have them, if so what brand do you like and where did you buy from.

Looking for a 24v system to live in my console, TM comes off the boat during the summer but the batteries stay in so if i can reduce weight id like to. I know the cost is there but I like to buy once and cry once, so if i get 10 years out of it I feel I got my moneys worth.

Get a single 24v 50ah lifepo4 battery and put your starting battery and tm battery under the console. Will get some weight out from the back and put it in the center. I’m assuming that your starting battery is in back.

I have two 100ah Battleborn batteries in the front and together weigh 62lbs. Have gone on four day trips and never ran out of power. They now make a 50ah 24v battery that weighs 31lbs and should give you more than enough juice for a long day on the troller. Ten year warranty is nice as well.

A 12v system will wear a battery down much quicker than a 24v system. If you can, go 24v for added power and run time. Just have to deal with the added cost though.

The voltage on the lifepo4 will remain at or above 12 volts until the charge is depleted. Lead batteries will drop below 12 volts and not provide enough power for the TM, much sooner than the lifepo4.

A 24 volt system with lead acid batteries, either agm or wet should still give you plenty of power in a day. Main advantage of lifepo4 is size and weight and longer runtime.
