I upgraded to lithium and removed these 3 batteries that were in the boat when i bought it. 3 commercial grade battery’s. I used 2 in series for my 24v 80lb ultrex. Still full power for 5 to 6 hours pulling jigs at 1.2mph. Not exactly sure of age but they should last for a while longer. Just wanting to help someone with a budget
