I recently bought my third UTV kit from you, and this is the first one that has the new UTV-SBI-15 isolator. The first two kits are fantastic and do an excellent job on our RZRs, and I always believed they were about as good as it got, but with this current model, you have truly […]
Great product! Wanted to let you know the True Smart Battery Isolator we purchased from you is the simplest most trouble-free system I’ve ever used for battery isolation. Swayne T. ,
Mr. TRUE, Welcome to my circle of friends you’ve earned it. I First used your TRUE SBI isolator on my boat for my electric motor battery. Then put one on my Truck with the snow plow and now I had the dealer put the TRUE UTV Dual Battery Kit on my new Arctic Cat Prowler […]
Wham Bam thank you man! Just returned from a 6 day long trip on my Yamaha Rhino and we were the only one of the three units that did not have starting problems due to battery discharge situations. All three had dual batteries but I was the only one with the TRUE Universal Dual Battery […]

This would save power of the starting battery especially when the charging source becomes insufficient. This is a hybrid type of technology being applied, utilizing state-of-the-art device and […]
Dear Dennis, I wanted to send you a note to say happy holidays and thanks for selling me on the idea of using your new battery isolators. My little shop is now installing about 10 of these a month on both new and older model boats. I can honestly tell you I disliked using […]
Dr. Hogan, I received the BSR’s and dual battery kit last weekend. I must admit I was skeptical of the ease of installation and the price was a little higher than the battery isolators at Wallmart but after talking with you I decided to give this a try. I have installed diode type isolators before […]
