The True® UTV-SBI-19L lithium battery isolator was developed primarily to work with the latest lithium batteries that have a voltage of 13+ volts and stator-style charging devices. You must have at least one lithium battery to allow the use of the product's special PEP.
Built for Lithium. Proven in the Field. Trusted by UTV Owners.
Lithium batteries are a distinct kind of battery with sophisticated characteristics that need special management programming to preserve. The lithium batteries that are accessible for this business are 13+ volt batteries, not 12-volt batteries; thus, the
True® lithium battery isolator is configured to handle this and other characteristics that might not be as evident. We are happy to present the recently released lithium battery isolator designed specifically for UTVs after taking the time to do the necessary studies and testing.
The only completely adhesive-sealed, 100% waterproof cables in the market are included with every True® lithium battery isolator. There are two mounting options for this isolator. Use a 3M Dual Lock fastener or hang it from cables. Outstanding performance and quality from True® Amalgamated.
As of right now, no alternative battery isolators made specifically for lithium batteries are available on the market.

Is It Safe for My Vehicle’s Warranty?
The True® UTV isolator brand (often sold as the True® UTV-SBI series) is designed specifically for off-road vehicles and dual battery setups. These isolators are built with heavy-duty, vibration-resistant casings, waterproof cables, and heat-resistant components. Importantly, the manufacturer states that their kits are intended to preserve your vehicle’s warranty when installed correctly, since they don’t interfere with the factory electrical system but instead manage power between primary and auxiliary batteries .
Key Points
Warranty Safety: True® isolators are marketed as warranty-safe because they connect in parallel without altering OEM wiring.
Ease of Install: Most kits are DIY-friendly with clear diagrams and minimal wiring (often a 3-wire setup).
Durability: Designed for UTV/ATV environments—anti-vibration, waterproof, and heat-resistant.
Specialization: The UTV-SBI model is the first smart isolator built specifically for stator-based UTV electrical systems .
Things to Keep in Mind
Proper Installation: Incorrect wiring could cause electrical issues that might affect warranty claims.
Manufacturer Policies: While True® isolators preserve warranties, some vehicle manufacturers may still scrutinize aftermarket modifications.
Documentation: Keep receipts and installation records in case warranty questions arise.
✅ Bottom line: The True® UTV isolator brand is generally safe for your vehicle warranty when installed properly.
Can I monitor battery status?
Yes. The kit includes a dual-display waterproof voltmeter and a blue LED indicator on the isolator itself, which lights up when the batteries are connected and charging.
What makes this isolator different from standard ones?
It’s specifically programmed for LiFePO₄ lithium batteries, which operate at higher voltages (13.2V–13.5V). Standard isolators often fail to engage or disengage properly with lithium systems, risking accessory drain or undercharging.
How does the isolator know when to connect or disconnect?
It uses voltage-sensitive logic:
- Engages at 13.5V to connect both batteries for charging
- Disengages below 13.2V to protect the starter battery
There’s a built-in 10-second delay to prevent false triggers.
Is it compatible with other battery types?
While optimized for lithium, it also works with AGM and lead-acid batteries, making it versatile for mixed setups.
Will it protect against electrical surges?
Yes. The isolator includes ignition surge protection, shielding your system from voltage spikes during startup or accessory use.
Requires at least one lithium battery in the setup

Needed for Lithium battery in Honda Pioneer 1000
I was using the previous model with my dual battery setup in my Honda. I decided to go with Lithium dual battery kit which required this update. Previous model still work well after 6 years.

Fantastic product, and this business takes phone calls.

Simple to set up. Functions as it ought to, or as I would have anticipated. With the help of my dual voltage meter, I can keep an eye on both of my UTV’s batteries and make sure the isolator is operating. is still operating well after being placed for more than a month.

This is a quality item. I have been running with it installed in my 2020 Honda Talon along with the second battery for about two months now and have had no problems. Easy to install and the cable lengths were perfect for my installation.

Works exactly as advertised. Some of the cables were too short for installation on my SXS and secondary battery installation, but that is not the fault of the manufacturer. Installation was not particularly difficult.
