This is the kit needed for snow plows, stereos, and high power needs in a RZR. The kit has 2 batteries which are predetermined to not only fit in the RZR, but allow you to run devices for lengthy periods of time without any worry of not having enough power to restart your machine should you stop. In particular when plowing you can pull up to 300 amps when at its max pulling power. That’s a ton power which would kill a stock battery quickly! We make a winch wiring kit with a resettable breaker for just that very reason. With this dual battery kit we are using the proven technique of isolating power to charge the battery from the starter battery first and when fully charged switch to the accessory battery and charge it fully. This assures you will never be left stranded with a dead battery to start your machine to get home. The idea of this kit also allows the winch to be run for extended periods when snow plowing and not the battery and stop you from finishing plowing. The batteries consist of an Odyssey PC925 as the starter battery, which will be located in the stock second battery location in the RZR. The main battery will be replaced with an Odyssey PC1200 and will become the accessories/winch battery. This is double the amount of battery capacity for just the accessories alone! The PC925 has been the go to battery for the RZR 800 for years now and gives you all that you would need for starting and the essentials of the machine. This also has the correct wire gauge for carrying the amount of power needed for the kit. This has everything you need to do the installation including wire and terminated ends. Please specify which machine you have for proper wire length to be included.
