    Most bikes need another battery. This makes the install easier.
    I installed this on a Razor Rambler TRL with 2 stock 48v batteries. I installed the second battery in the rear of the seat by removing a section of plastic and then foam the same size as the battery. After a couple of test runs it seems to work just fine. This should with double the battery life.

    This allows two batteries to be used in my Caroma eScooter.
    This allows two batteries to connect to my Caroma eScooter. The battery that I’m adding is rated at 48V14AH and it is much larger than the original battery. I’m planning to use only the 48V14AH rated at 300 watts. The distance travelled between recharging will be much longer. The original battery can also be used and it is also 48V. Since the original and the second battery are both 48V they can both be used together.

    Muy buen producto funciona correctamente solo que cuando se conecta la segunda batería siempre salen chispas pero en lo general funciona bien ahora tengo mayor autonomía en mi bicicleta y es super fácil instalar
