Here are several ways to make sure they are installed correctly: 1. Measure the voltage of the batteries with a multi-meter to see if all the batteries voltage is normal. 2. Listen. If the balancers are connected correctly, they will produce a high-frequency sound. Because the sound is quiet, you need to get close to the balancers. The more balanced the batteries are, the smaller the balance current it will have, and the softer sound they will make and vice versa. If they are connected the wrong way, you won't be able to hear the sound.
