WBL 120

WhisperPower Battery Links are smart switch regulators that automatically connect two battery banks if the charge voltage rises above a certain value for at least five seconds. This means that the battery banks can be charged from the same source. To protect the battery banks they are separated from each other as soon as the voltage drops.
