Product Reviews

  1. Multiple battery charger cord!

    Posted by Ed Moll on 1st Dec 2016

    This looks like it will do everything I need!

  2. A must-have addition to your charging setup.

    This V-connector is a great accessory for those with a boat. I have 2 batteries, and it has always been a bit of a hassle charging both of them in the off months (and even during the summer season after a lot of use).
    I can just plug in and charge/float/condition both batteries at the same time. I am sure that adding a second V-connector will make it painless to charge 3 batteries for those who have that many.
    Coupled with the EZ-connector for a clean installation, this is much better than an on-board charging system.

  3. Well executed design and engineering / fantastic quality and reliability

    I've ordered this and several other components from BatteryMinder to support the charging and desulfating use of the Concord Battery specific charger used in my airplane. I can state with absolute confidence that BatteryMinder's products are superior to all others that I have used and I am much more than satisfied at having this product to use in keeping my plane in the air. Thank you BatteryMinder, Gary Bunting (alias: 'Cubmeister')
