True® Lithium Battery Kit: Advanced Isolation for 13V+ LiFePO4 Systems
Lithium batteries are a different type of battery with advanced attributes that require unique management programming to maintain those attributes. The (LiFePO4) lithium batteries available for this industry are NOT 12-volt batteries but rather 13+ volt batteries and need a lithium battery isolator programmed to deal with this and other attributes that may not be so obvious.
We’ve taken the time, and done the research and testing and are pleased to announce the just released UTV-specific LITHIUM Battery Isolator with Connecting Kit that features the True UTV-SBI-19L smart battery isolator for Lithium Batteries built from the ground up for stator charging mechanisms. This Lithium dual battery kit provides you with the absolute best charge management of your accessory battery while protecting your primary battery for starting.
True lithium dual battery kits feature the industry’s only fully adhesive-sealed 100% waterproof cables. These kits allow for mounting with the included 3M Dual Lock fastener or leave suspended in cables.
Unmatched quality and performance from True Amalgamated.

Frequently Asked Questions!
1. 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.
2. What is P.E.P. technology?
Power Efficiency Programming (PEP) maximizes charging efficiency from stator-based systems commonly found in UTVs. It ensures both batteries receive optimal charge without overloading the system.
3. 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.
4. 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.
5. 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.
6. How easy is installation?
Very easy. The kit includes:
- Pre-cut, adhesive-sealed waterproof cables
- 3M Dual Lock™ fasteners
- Simple 3-wire connection—no ignition tapping required
It’s designed for plug-and-play use in UTVs like Honda Pioneer, Polaris RZR, and Can-Am.
7. Will it protect against electrical surges?
Yes. The isolator includes ignition surge protection, shielding your system from voltage spikes during startup or accessory use.

Overall, the Install went well. Unfortunately the Negative battery is about a 1 1/2” too short. And I had to improvise with a homemade cable. I contacted the seller and they are sending the correct cable. Very prompt reply

This is a straightforward fix for an issue that many of us RVers encounter. Installing an alternator is a difficult task. This small gadget ensures that my accessory battery, which powers my audio and other devices, doesn’t drain my starter battery. When we drive, my RV is also connected to this battery.

The start battery of my car has never discharged below the safety threshold. When the lithium battery isolator changes, you can hear it. It has been functional for several months.
Kenny Britz –
Problem solved. Two ahm batteries were installed for the airbag system. There is no flickering of the electricity when compressors operate. Batteries are consistently completely charged
Joe Cerulo –
I work as a volunteer for events. I love ham radio. In addition to one scanner and flashing lights, my car has three transmitting radios. A lithium battery located in the trunk powers all of these. The car starts every time. The Lithuim battery isolator is to be thanked.

Excellent product, simple installation instructions, true to description. Almost a year has passed since I installed it, and I have never experienced any problems or needed to worry about it again.
