Voltage Guard

Installing a battery protection device like the Dolphin Voltage Battery Guard is a smart investment for anyone using batteries in vehicles, solar systems, marine applications, or backup power setups.

Who Needs a Battery Protection Device?

• Vehicle Owners (cars, trucks, motorcycles, classic cars)
• Marine & RV Users (boats, campers, off-grid systems)
• Solar Power Systems (prevents battery drain during low sunlight)
• Backup Power Users (UPS, generators, emergency systems)
• Industrial/Commercial Equipment (forklifts, machinery, telecom systems)

Here’s why it’s essential:

Prevent battery discharge

Deep discharge in batteries – especially lead-acid, gel, or AGM is critical to prevent cell damage caused by sulfation. Batteries have a limited number of charge/discharge cycles. Deep discharges shorten this lifespan significantly and cause irreversible Damage.

Reliable power reserve

Below a certain threshold, a battery can no longer deliver sufficient power for critical functions. Voltage Guard disconnect automatically. It allows you to set a lower disconnect voltage to safeguard the battery while maximizing its usable capacity.

Remote battery main switch

Voltage Guard can be remote operated with an additional switch and act as a battery main switch eliminating the need to physically access the battery. It offers several practical and safety-related benefits, especially in vehicles, marine applications, industrial equipment.

LED and buzzer

No display needed thanks a build-in tri-color LED indicating operational status. It allows an instant visual feedback without needing to check a screen or manual. VLT 70 includes a built-in buzzer providing immediate sound cues.
