my friend that is a very heavy battery in your inflatable
i suggest a gel battery from a wheelchair or old person scooter
very light and has power (deep cycle) or granny would be stuck on the street
northern batteries ub12350 more than enough, i ran it full power minn kota 30lbs for 2hours straight and used a third of battery as per the minn kotta battery tester.
in my setup I use 2 gels, one 35ah and the other 20ah. I use the 20 to power also my air pump because I use to pump the boat by the car it needs the dc plug but I can't always get the car by the water. 35 and a 20 is total 30lbs one 35 is 20lbs which is so much lighter than the marine types. More power more weight.
You can buy these batteries any battery specialty place lots of nursing homes toss these.
Charge them after ever use I have been using mine for 3 years I bought brand new, never leaks very safe has a carrying strap/PORTABILITY.
