    Purchased these (2) to replace 4 AGM batteries in my RV. Half the weight. Easy to mount & secure with feet everywhere. The AGMs were total of 600 AH & these are 540 AH, but work out to 165% total useable total energy. An old Xantrex TruSine 2.0 Charger/Inverter/Switch & 200 Watt solar Renolgy system with PWM. Programmed both for Lithium charging at 14.4 & 13.5 float. But AGM profile is very similar at 14.3 & 13.4 float if I was lazy. CPU controlled device keeps RV engine battery charged & the engine can also charge these two as well. I are pleased with how easy it was & how much information is on your website about details of your charger/inverters/switches and how to program it for lithium. Thanks Guys & Gals!

    So, I’ve now been running 3 of these in my 5th wheel for a few months. They have performed flawlessly I must say! And the fact that these can be installed in so many different ways is just great! Mine are installed in a standing position which has aloud me to put all 3 in a space where only one standard size D8 would fit (without building shelves). I highly recommend the GC3 and really any Battle Born battery for that matter!

    The guys at Battle Born helped me get the right products to convert from four 100Ah AGM batteries to a single GC3 270Ah battery in our Airstream Interstate Sprinter van. I added the Victron Energy MultiPlus Compact 2000 W charger/inverter that Battle Born provided preconfigured with the charge settings for the GC3.

    We were able to test the system while off grid on a trip last month in Utah and the system performed perfect and made off grid camping possible where our old and tired AGM batteries would not make it through a night. Next morning we had 70% SOC and our 300w of solar panels had the battery back to 100% by 10:00am.

    Great products and great support. Thanks Battle Born!
