I know its based on my speed but how long will the 2, 70ah AGMs last (roughly) running a 24V 70lb IPilot at about 60%?

My two lead acids only last me maybe 2 or 3 hrs now (108ah + 80ah).... They old so the reason im looking for new ones.

All good stuff comes from US.
I know a dealer that was bringing those from US here but he stopped due to the high cost. Those kind of batteries are expensive.
The best deal for your buck now are AGM from Costco (70AH) each at $170+tax and they weight 21Kg each.
The average of lead acid is 11Kg/35AH capacity.
I did gave up my quest for powerful batteries when I start to use 2.5Hp gas 4 stroke.
I use approx. 1Liter of gas for a good trolling  (4-5 hours) on big lakes.
I can go easy at 14km/h sprint to my spots and the range is clearly bigger than the electric.
Next year I will try a 3.5Hp (18Kg weigh of motor). The idle speed of a gas motor (4 strokes) is the ideal speed for trolling (around 3.2Km/h) at least for my dingy(kayak) as long the motor is in 2 to 4Hp range. I did tried a Honda 4Hp, nice kick but heavy to carry (30kg.)
Keep in mid that:
24V - aprox. 1Hp
48V - aprox. 2Hp
I do have a 36V trolling (101Lb) that can be powered by 48V.
It is strong and good the problem is the batteries.
I will keep it for small exits (rivers, small lakes)
For the big waters (Ontario, Erie, Huron, Simcoe) the gas is my friend.

One battery of 70Ah has the weight of 21-22Kg
One 3.5Hp motor (4 strokes) filled with gas the weight is under 20Kg.
This is the bottom line for me at least for now.

Have fun and be safe.

Anyone know where to find any 100ah lithium ion batteries. I need 2 to make 24V to run my Minn Kota IPilot.

I am aware of their costs. Everything I am finding is US based...
