Note: The bundled charger is intended for onboard use in golf carts. It should not be used onboard with mowers since debris can block the fan. You can add an RXV plug and use the existing charge port or leave the in-line plug that comes with the charger accessible. However, for simplicity, the HTRC P3648 charger is recommended.
