    Have purchase 4 in the past month. Application solar. Unbelievable battery. I cannot believe how well these batteries are constructed with quality components. Fantastic warranty!

    In a word…. Incredible!!!!

    We have six of these charged by 1,200 watts of solar powering all of our 12V DC loads and 120V AC outlets in our 35′ full time 5th wheel with a residential refrigerator via a 3,000 watt inverter. They work so well we don’t even feel “unplugged” even though we are 98% of the time.

    These batteries are simply outstanding. I have two of them in my travel trailer and plan to eventually add a third. They charge quickly and efficiently with solar panels and MPPT controller. Of all the upgrades we’ve made to our travel trailer, this was by far the best investment. It allows us to camp off grid in the beautiful places we enjoy while providing the power we need to be comfortable and enjoy the experience. The up front cost may seem high compared to other battery options, but with such a long product life-span, warranty, manageable size/weight, and lack of maintenance requirements, they are priced well.

    I use 2 BB 100ah batteries in my Four Wheel Camper. They have provided all the power I need to keep the furnace, fans, refrigerator, water pump, lights and everything else running without a problem. I can go off-grid for a week without any shore or solar charging needed. The weight savings, BMS and faster charging capabilities of these batteries make the cost worthwhile! For smaller campers where weight is usually a concern these batteries are the best solution.

  5. garrycoufal (verified owner)

    Update- I have purchased 12 of these batteries. I have 6 each on two different solar charging setups. I could not be happier with the quality of the product.
