For the amount of added cost for the eco charger I may just do ring terminals from the batteries to an SAE plug. Then wire another SAE plug to the charger and not mount it in the cart.

I spoke with ampere time regarding this charger.

They said it will work but will take 12.5 hours to charge? This is an 8 amp charger as opposed to the 2.5 (i believe) charger you recommended. Re
