    Customers are dissatisfied with the melting of the auto battery. They mention that the negative terminal literally melted after about 30 minutes of use, the terminals overheat and break easy, and the battery seizes and melts. The positive terminal gets hot during a high-duty cycle, and it heats up and burns skin. All the connectors were hot and the metal part already burned out.

    "...The mighty max charger that is recommended gets extremely hot, little worried about that." Read more

    "...PRODUCT, WELL MADE, COMPACT, BUT IT IS HEAVY, POSITIVE TERMINAL GETS HOT DURING HIGH DUTY CYCLE." Read more

    "...burning and surely enough when we got back it was the battery seizing and melting. All the connectors were hot and the battery itself was overheating." Read more

    "A decent battery for the price. The terminals over heat and break easy. I’d consider replacing them to make it a better product." Read more

    Perfect little battery

    Perfect little battery
    This battery works great. I currently have a Explorer 420x Inflatable Kayak 14ft and this can power me at full speed 5-6mph for 2 + hrsI used the MinnKota Trolling Motor Power Center which works great but i did have to install some high density form to stop battery from moving around inside. Battery is less than 40lbs case included. Been out 2 entire weekends using it constantly and the best way to get more life out of this is only use motor when tired of paddling or need to get out in quick...
