  1. Joyce Colbs

    The lithium dual battery isolator has operated according to plan. The wet cell starting battery is also properly charged, and the lithium batteries can be charged without overtaxing the alternator. Also, it stops the wet cell starting battery from being overcharged when using the generator or shore power.

    When upgrading to multiple lithium batteries on a motorhome, the Large Lithium Dual Battery Kit is required. If not, you risk overworking your alternator or charging your new lithium batteries too slowly.

    We mounted this on our F450 to aid in fifth-wheel lithium battery charging. So far, it has been performing excellently. The only concern is the F450’s lack of instructions.

  3. Marcus

    My 2nd purchase of the Lithium dual batter yisolator, and by far the greatest one in terms of functionality! An essential item if you have two batteries. Without a doubt, I would purchase again!

  4. Mark

    The opposite battery jump option has saved my bacon several times. It works as described. Use with my Lifepo4 and BMS. Charges my batteries while I drive. Worth every cent!

  5. Jonathan Gray

    It seems to operate well and is simple to install. Have been on the truck for several months. Seems to be functioning well. There were no difficulties with drainage.

  6. John Harryson

    This Lithium dual battery isolator has fulfilled its promise to the letter. Maintaining my auxiliary batteries charged and ready for both remote work locations and camping has not presented any problems for me.

  7. Steve Brown

    This is a good feature since it isolates the two lithium batteries and connects them automatically. The button’s operation is a touch complex, but the rest of the product is fantastic.

  8. Kelly Stirling

    This is an excellent Lithium dual battery isolator. I used it briefly in my pickup before switching to Lifepo4 batteries. My lead acid crank battery had a dead cell, which emptied my auxiliary battery within a day or two. I can say the emergency button works; follow the directions…..I wish there was a model that isolates at greater voltages for lithium-ion batteries.
