Mighty Max Battery 12V 55Ah Power Boat Pontoon Electric Trolling Motor Deep Cycle Battery

Have used this battery multiple times this summer. It is great. It works flawlessly with my 46lb trolling motor. After being out on the water trolling for 2-3 hours it still has nearly a full charge. I had good luck with the Might Max 35AH battery but this 55AH is so worth the extra $40.

Almost 2 years old since i bought this. Its spent plenty nights in a battery box sitting in my truck during freezing nights, and its still taking charge and holding voltage just fine. battery tech changed a lot since i bought this, so i probably wouldnt buy again or use for a trolling motor any more, but im still getting use out of this for running a heavy duty 12v tire inflator. Depending on price...it might be a good choice for many uses and projects.

Excelente batería , la utilice en un bote inflable y motor electrónico. Nos dio 4 horas de diversión.

Bought this for a 4 person blow up raft. It worked great but is very heavy.

I bought this for my kayak for which I have built a transom to add a trolling motor (I will often go out for a long 3-4 hours day and like to be able to add some motor power). The motor is a Newport electric motor with 35 lb. thrust capability. I have used that motor at highest speeds for about 1 1/2 hours often pulling a tethered kayak and the battery has only dropped from 13.2 to 12. 2 volts. (they recommend to not go below 11 volts) However, it is heavy!! At first I had it placed behind me, but between my weight and adding battery weight to the back in addition to the weight of the motor, I only had about 1 inch leeway before the kayak would have gone under. I now place the battery in front of me and it fits perfectly between my legs as they are spread to the footholds in the kayak.

The battery came nearly fully charged (there was some discharge from being off charger, but nothing significant). It powered my 36lb thrust trolling motor roughly 4 hours at full power - pushing a 13' fully loaded fishing kayak with 15-20mph winds, and 4' - 5' waves. I wish my adult diapers worked as good as this power cube. The battery box says that there is still over half a charge left. That's pretty impressive for the price. I'd buy it again and suggest it to a friend.

Batteries just fine. Don’t take it right out of the box and use it or you’re gonna be disappointed. You have to put it on a trickle charge until it’s 100%. And I would definitely recommend their recommendation of not taking it below 25%. This is not off the cuff advice, I’m 58 and my daddy was a mechanic so I know the drill. JTP

I bought this battery as a 12 volt power supply for my CPAP. When fully charged I found that I can use it for at least four nights, 8 hours each night on a single 100% charge while boon-docking while out in my camper. To use with a CPAP be sure to get the proper 12 volt DC power supply cord recommended for you brand and model of CPAP. My CPAP cord came with a male cigarette plug attached and all I had to do is plug it into a female cigarette plug with alligator clips like this one https://www.amazon.com/BESTEK-Cigarette-Lighter-Battery-Extension/dp/B00JOY6U7U/ref=sr_1_5?dchild=1&keywords=12+volt+cigarette+female+with+glipes&qid=1598816232&sr=8-5 . Be sure to test it out at home before you leave to make sure it works properly. I also used it to charge cell phones and other digital equipment while boon docking.
