    Expansion box

    Finding Cutting Edge is has been a blessing to me. All the big named all in one companies charge so much and you can’t even expand them. With Cutting Edge you can add as many batteries to your system s as you please. This expansion box is so simple to connect and it works perfectly, just as the rest of their products.
