There are sealed lead acid batteries. I use them all the time for lights on my bike. They will not leak whenn rolled about. There is also heat shrink tubing that when heated also emitts a clear sealant that seals the joints. These are used for underwater connections at 200 ft. A well pump at 230v that is emersed for 10 years or more. Niels >Julio, > > Sounds like your pump is much more powerful than the small portable >one I used to have.
