I have an extra two bank that I replaced with a 3 bank and also have a brand new 1 bank that I'm not using right now. My question is, can you use these onboard chargers to hook up to stuff like zero turn mowers, riding mower tractors, etc? Wondering if they will work on standard batteries that are not marine batteries? If I have to sell them I will but thought they might actually work on other items. Thanks............
