Why you should buy this $1000 device for your sailboat – Wakespeed Alternator Regulator

What this video covers

Lithium battery banks pose a significant risk to standard automotive-style alternators because lithium batteries accept high current until fully charged, potentially overheating the alternator or causing diode failure if the battery management system (BMS) suddenly disconnects.▶ 0:51 A Wakespeed alternator regulator mitigates these risks by monitoring battery voltage and alternator temperature, then throttling output to prevent overheating.▶ 3:07 The device allows for precise charging profiles and can communicate directly with compatible BMS units via CAN bus to optimize current delivery.▶ 7:09 For high-capacity banks, such as a 600Ah setup, users often pair a Wakespeed regulator with a high-output alternator like a Balmar 250.▶ 5:07 This configuration requires additional hardware, including a mounting bracket and a secondary belt, which can significantly increase installation costs.▶ 5:36 While the regulator protects the alternator, engine room ventilation remains critical, as high temperatures reduce alternator efficiency.▶ 6:10 The Wakespeed system is programmable via DIP switches or a laptop, allowing users to set specific temperature limits for diode protection.▶ 3:44
