William Parke –
Just added an auxiliary battery to my Honda Pioneer 1000.
This is working great and was easy to install.
I like being able to charge both batteries with 1 battery tender.
I have dual battery gauges so it’s easy to see both batteries are being charged.
when running accessories I can see the isolator is working when the engine is not running only the auxiliary battery voltage is drawn down and the main battery is unaffected . Charges both when running as it should.

I had purchased an Aopec smart battery isolator before and had nothing but problems with it so I was hesitant to purchase another even though it was a different company simply because of how these work. Well I broke down and ordered this one for my Polaris Ranger and after installing it just works, Have been using it for two weeks now without any issues. It is also smaller and takes up less space.

Easy to install and wire. Works as described. It is a must have if you run a second battery on your side by side
Vince Amazon –
A very good decision
Best battery charging and isolation management choice in the market. I have soaked it and covered with mud during trail riding and the waterproof casing works well. The price is competitive for this single unit.

Perfect for replacement for my old dual battery isolator installed in my Honda pioneer 1000-5
