Abstract
A battery reserve system for open-air carts and a method for its use are taught. The system contains a reserve battery bank and custom designed brackets, compatible with and attachable to small, low-speed car frameworks currently structured to hold only a single battery bank, to support the reserve batteries while maintaining the cart's balance and stability and for use with newly built enlarged carts. The reserve battery system increases the currently available cart's travel distance to minimally twice the distance provided by the cart's single battery bank without requiring battery charging. One currently available electrically powered golf cart is a Yamaha DRIVE®. The reserve bank of batteries can be a 48-Volt bank of any desired configuration. A battery disconnect switch for connecting or disconnecting the reserve battery bank with the initial battery bank of the electrically powered golf-cart is provided. Space for golf bags and other accessories is maintained.
