While InPower’s VCM12 Low Voltage Disconnect is perfect for controlling small parasitic loads and extending battery life during long periods of inactivity, what about the high-current loads that can drain your batteries quickly on the job? Large motors, sub-system circuits, and other high-power devices can deplete even large battery banks at an alarming rate.
To protect your vehicle’s power system, InPower’s LVD21 and LVD3 Low Voltage Disconnects are designed to shut off these high-current loads before they completely drain your batteries.
Why Smaller Loads Aren’t the Only Concern
Many upfitters already rely on the VCM12 for managing smaller, often overlooked loads that can easily drain the battery, especially when powered by the main chassis batteries. However, larger loads are often run off auxiliary batteries that are typically isolated from the chassis using products like InPower’s ABS3. So, why should you still use an LVD to protect your auxiliary batteries?
The Importance of Battery Voltage Protection
Every battery has an optimal operating voltage range. As a battery’s charge depletes, its output voltage drops, and the battery can deliver less and less power. Keeping the battery within its ideal voltage range is crucial both for optimal power delivery, and for prolonging the battery’s lifespan. But when the voltage dips too low, continued usage can cause irreversible damage to the battery’s chemistry.
If power continues to be drawn from the battery beyond its optimal range, the battery’s cells begin to degrade prematurely. You’ll notice that even after a recharge, the battery will hold less power and become increasingly unreliable until it finally fails when you need it the most.
Why Use an LVD to Protect Your Auxiliary Batteries?
Truck batteries are expensive and replacing them prematurely can add up quickly. And powering loads off of depleted batteries not only damages the batteries, but the lower voltage of a dying battery reduces the effectiveness of attached equipment, and makes it work harder. By using an LVD to disconnect high-power loads before the battery voltage gets too low, you can extend the life of your batteries, and save wear and tear on your equipment, saving significant costs in the long run.
The InPower LVD Series: Built for Heavy Loads
The LVD21 and LVD3 Low Voltage Disconnects are designed using the same principles as our SSC21 and SSC3 contactors—combining ruggedness, customization options, and simplicity. These disconnects offer the same battery protection philosophy as the VCM12, but in a more powerful and capable form, able to handle 100- to 300-amp loads.
Whether you’re protecting your chassis or auxiliary batteries, InPower’s LVD products are tailored to keep your batteries in top condition, maximizing their lifespan and performance.
Protect Your Batteries, Protect Your Investment
Don’t let high-power loads drain your batteries prematurely. With the InPower LVD21 and LVD3, you can protect both your vehicle’s primary and auxiliary power systems, extending the life of your batteries and saving money in the process.
