I ran into a member that made me a custom battery back up for my ecotech mp40s. I did not want to spend 200$ on the ecotech one so I found @TheHarold and helped me from start to finish. He went above and beyond even suggesting a battery, modifying cables, and order me a trickle charger. Going this route is superior because it’s stronger than ecotechs battery ( I tested two mp40s at default back up power lasted 29 hours (30Ah) but capable of supporting a much larger battery. The custom voltage box gives me a way to know if I need a new battery. Also get the option to use a lithium battery which I hope allows me more time until replacement. I suggest checking him out if you want a plug and play battery back up that can save your tank from a power outage. Thanks man it was a pleasure doing business and product works great
can’t wait to get it mounted!
