Batteries are the foundation of your energy system. Choosing the right batteries and pairing them to the right charge sources can make the difference between a carefree adventure or a systems failure nightmare. BRJ Solutions LLC offers a variety of battery options from traditional AGM to different types of lithium systems to Firefly’s carbon foam battery technology. We can help you decide which batteries make the most sense considering you’re goals and your current set up. Below are two of our most innovative and popular battery systems.
Firefly's Oasis AGM batteries use exciting new Microcell carbon foam technology that gives them qualities similar to a lithium battery. They have a longer life cycle than other lead acid batteries, plus fast recharge capability, a high charge acceptance rate, continuous power through the discharge process and full capacity recovery after discharge.

Firefly Batteries Currently Come In Two Sizes
Which battery is best for you project? The answer might depend largely on the size of the space you have available. G31 batteries are our most popular, simply because their size makes them more versatile than the L15+, which must be installed in numbers divisible by 3. Each G31 has 116Ah and can be installed in any number that will fit your space. The G31 batteries will give you 3600 cycles at a depth of discharge (DOD) to 50% and 1000 cycles at a DOD of 80%.
The main benefit of the L15+ is in the number of cycles you’ll get. At a 50% DOD, the L15+ will give you 4900 cycles and at an 80% DOD, 1500 cycles. The L15+ is a two-cell battery. It can be configured as a 2V 900Ah pack if you put the two cells in parallel or as a 4V 450Ah pack if you leave the cells in series, which is how they come off the shelf. They can also be rack mounted on their sides, but remember that they must be installed in numbers divisible by 3. (This battery is alternately referred to as the 2V, 4V, L15, or L16 battery. These are all the same battery.)
Please note that although an E31 battery is listed on the Firefly website we do not expect to see it in production very soon if ever.
