Next-Generation True® UTV Dual Battery Kit with Dual Display Volt Meter
The meter can mount anywhere you have a flat surface that can be drilled with a 29mm (1-1/8”+) hole. The True® dual battery isolator kit includes 8 ft. of duplex wire, a relay socket, and all the cable end connectors needed for a complete install. The only connectors you will need is to connect the power and ground wires to the appropriate sources. See the additional pictures or download the instructions for more information.
“Ordered the kit, had a couple of questions about where to mount the isolator and how long the cables are. True’s support answered pretty quickly, and I got a tip that helped hide the wiring from splash damage. After using the UTV dual battery isolator for several months, it’s still solid as day one.”

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.

This is actually a simple to install battery charging management accessory. Having an extra digital voltage gauge is a huge plus. I can see other brands in Amazon and eBay but this one is well recommended.

Missing parts in kit
Reviewed in the United States on Feb 8, 2022
I received the prepackaged kit, but the 18″ 6 ga positive cable was missing!
Really? Who examines the kits? Also, although it doesn’t really matter, a company’s attention to detail tells me a lot about them.
The instructions explain how to connect the blue and green wires to the batteries and according but the dual battery diagram in their directions displays colors that are completely different from the ones of the batteries that are designated. Please avoid confusion. It’s terrible that I can’t even connect the battery isolator without buying my own cable right away.
Check to see if they can send me the missing component by overnight! Received the missing part the next day.

Longer positive and negative wires are required. the negative, at least. This is not an inexpensive kit, and while there is plenty of hardware and additional wire included, several reviews mention that the negative was insufficiently long, requiring the user—like me—to buy one in order to complete their installation.

Perfect for UTV
Installing this was quite easy, and having a volt digital meter is a tremendous benefit. Although there are a few different brands, I strongly suggest this one.

This is now the second time I have bought this product as my first went with my UTV when I sold it. If you’ve got a second battery and a bunch of accessories YOU NEED this UTV dual battery isolator kit

Installation Cable is very short! TrueAm fixed promptly
The dual battery setup kit went smoothly overall. The negative battery is, regrettably, about 1 1/2″ too short. I had to make a makeshift cable as a last-minute solution. The vendor is shipping the right cable, according to my correspondence with them. Very quick response

It fits and works well. Simple to set up
Excellent product. Although the main wires’ length might have been increased for more mounting options, the quality was excellent.

Works for me!
This is what I bought to power an additional battery for a winch on my side by side. All is well thus far. I currently just require one battery tender, which is an added benefit. The auxiliary battery is automatically charged after the main battery is fully charged from the tender. The dual voltage meter is what I advise. I can keep an eye on the health of both batteries.

Runs and functions as advertised, is simple to install, and comes with instructions. The unit has been greatly improved by having a dual digital readout in a single piece.
Reason for just four out of five stars; otherwise, five.
The positive cables ought to be the same length and able to extend halfway across the widest UTV on the market.
The negative wire is the same, if not somewhat longer.
Increase the size of the isolator’s mounting holes.
If the isolator cannot be found in a dry place, it should be a sealed unit. My particular one is in one that won’t get wet.
Having said that, it is a superb gadget and when it functions as it should, I would have no problem spending money on those small modifications.

Great kit
Simple to install. I ended up adding a battery disconnect and discovered that manufacturing wires is really simple. I constructed my own 4 gage wire crimping tool, but the auto parts store can also make custom lengths/terminal ends. Be cautious with the red plastic terminal covers… I broke one when tugging too hard on it.
Jason Prudhomme –
It’s easy to screw on and eliminates the need for wire clamps. The downside of this UTV dual battery kit is that the wires are short, with one ground being a few inches too short, as reported in all forums.
