Another Battery Question

Going to need trolling batteries soon. Want to switch to lithium. Have a 24v ultrex. What are the advantages/disadvantages of doing 1 x 24v 100ah battery versus 2 x 12v 100 amp hour batteries in series?

TIA for all responses

Right now I have 2 12-volt deep cycle batteries to power my 24-volt Ultrex. I like having 2 separate 12-volt batteries as this lets me just use one 12-volt to power my twin Minn Kota trolling motors I'm using as brakes for Livescope fishing while still supplying 24 volts to my Ultrex. I wouldn't be able to do this with a dedicated 24-volt battery. I do have a 100 AH lithium battery to supply my 2 1222s and black boxes and my 943 XSV in the dash.

I recently bought 2 Impulse 12v100ah batterys to run my 24v Ultrex. I have a 188. I bought too much battery. On a normal day I can fish 7hrs and use less than 15%. Both batterys are Bluetooth. If I were doing over I would stepdown 1 size and still have plenty of battery capacity

I also am using a Ranger 188P. My trolling batteries are still just the regular deep cycles that came with the boat. Will go to lithiums some day I'm sure.

KRW, if anything is worth doing then overdoing is better in my book:ThumbsUp:ThumbsUp

Hard to wrap your head around how much power is in those batteries for sure

Advantages of two batteries: Standard 12V charger. You may not need a new one. If one of the batteries quits, you can slap in any 12V deep-cycle and keep fishing and charging. You have 12V available for accessories or jump starting your outboard.

Advantages of one battery: Space.

With my 125's, I can get 14 to 16 hours pulling cranks, no problem.

100ah or 125ah if trolling,danny at performance fishing electronics has several guys trolling with the ionics he sells.
