Frequently Asked Questions

1. What is P.E.P.® (Proprietary Efficiency Programming)?

P.E.P.® is TrueAm’s smart logic that optimizes battery protection and charging efficiency.
It ensures the battery isolator only connects when safe and beneficial for both batteries

2. Does it regulate charging amps?

No, the SBI doesn’t regulate amperage. That’s handled by your alternator and voltage regulator.
The SBI simply controls when the second battery is connected based on voltage thresholds.

3. Why should I use this Prado 150 dual battery kit?

Prevents your main battery from being drained by accessories.
Provides dependable power for winches, lights, inverters, and other gear.
Ensures your truck always has starting power available.

4. Can I manually override or shut it off?

The male connector underneath can be wired for remote shutoff.
Inline switches are optional but not required—SBI handles disconnection automatically.

5. How do I monitor battery status?

Optional Single Meter Dual Display (SMDD) shows real-time voltage for both batteries.
Saves space and simplifies monitoring

6. What other vehicles can use this True dual battery kit?

It’s designed specifically for Chevy Silverado and GMC Sierra trucks, but can also be adapted for other GM vehicles with similar 12V systems

7. Is it compatible with all batteries?

The kit works with most 12V battery types (AGM, gel, standard lead-acid). It is not recommended for lithium batteries unless specified.

🔧 Core Features

Smart Features That Set True® Battery Isolator Apart

Performance-Driven — Supports demanding alternator outputs up to 150 Amps with ease
Automatic Dual Voltage Sensing Relay It intelligently detects when your main battery reaches a charging threshold, then connects the auxiliary battery. No switches, no guesswork—just precision automation.
No Voltage Drop Unlike older diode-based isolators (which can lose 0.6+ volts), True® uses solid-state technology that maintains full voltage to both batteries—ensuring faster charging and better performance.
No Alternator Rewiring Required — Installs directly at the battery with a simple 3-wire setup, meaning it’s compatible with modern ECUs and won’t interfere with factory wiring. That’s a win for newer vehicles and warranty protection.
LED Status Indicator for At-A-Glance Monitoring — Quickly shows when batteries are linked or isolated.
Built-in Ignition Surge Protection — Protects sensitive electronics from voltage spikes—UL1107/UL1500 certified for marine and automotive use.
Optional Dual Battery Voltage Meter — Enhances battery monitoring accuracy.
