You can store the energy generated by your solar panels with the aid of a dependable and efficient battery system, allowing you to access power whenever you need it instead of just while the solar panels are collecting sunlight.

Choosing the correct batteries is crucial, whether you are storing energy for emergencies and system breakdowns or running your electrical gadgets and appliances on a daily basis.

One of the best power storage system providers is the BigBattery brand which is a worldwide producer of recovered electronic lithium-ion batteries with the goal of making energy more cheap, accessible, and sustainable.

The BigBattery ‘s battery, which is made up of thrown away lithium-ion batteries that were initially designed to power electric cars, buses, and scooters, provides power storage systems at easily cheap rates, allowing customers to use such reused batteries to provide power systems for home solar clusters and help maintain electrical grids.

In this BigBattery review, you will get to know about this brand, their batteries lineup, reviews, and even some discounts to get from their store. Be prepared to learn about BigBattery’s futuristic energy system!

Overview of BigBattery

BigBattery began as a small-scale battery company in 2019 but has since evolved to become one of the major providers of off-grid, renewable energy batteries in the US.

Eric Lundgren, the brand’s creator, has dedicated his life to environmental and sustainability concerns. While Lundgren remained a staunch backer of the green energy movement, he discovered that costly and inefficient batteries were slowing down the renewable energy movement.

As a result, he launched BigBattery, a company with the simple goal of lowering the cost of solar storage by providing dependable and affordable solar batteries that are simple, effective, and functional.

The BigBattery brand is continuing to work toward its primary aim of decreasing the cost of solar power storage systems for the typical customer, believing that doing so would inspire more people to use solar energy.

BigBattery Questions & Answers (Q&A)

Customers usually ask the following questions when searching reviews for BigBattery. We help to answer and making it easier for you to make a purchase decision.

Is BigBattery products have a thermal management system?

The BMS (Battery Management System) is in charge of the temperature management system for all BigBattery products. Not only will this Thermal Management System prohibit the batteries from being used if the temperature is too hot, but it will also stop the batteries from being used if the temperature drops.

Is it possible to use my OEM charger?

No. Chargers for lead-acid batteries use different currents and voltages than chargers for BigBattery lithium batteries. Using your OEM charger may cause damage to your battery cells, voiding the 10-year guarantee. BigBattery offers a variety of chargers that are designed and balanced for each battery they sell.

When I disconnect the charger, why does the voltage drop?

The voltage decrease you saw is known as “bubble voltage” and is quite typical for Lithium Batteries. Other cell compositions react differently than LiFePO4 batteries. The relationship between voltage and load is not linear. If your voltage is between (13.3 and 14.6), (26.6 and 29.2), or (53.6 and 58.4), you’ll have much more than 99 percent capacity. This effectively indicates that “Bubble Voltage” represents less than 1% of total capacity, and thus the decrease when a load is put is instantaneous.

How long the BigBattery battery products will last?

Batteries made of lithium iron phosphate (LifePO4) may be recharged between 3000 and 7000 times. If you cycle your battery on a regular basis with an 80 percent DoD (Depth of Discharge), you may expect your battery to last even longer than 10 years.

I’ll discuss how this pack differs from the other packs currently available on the market. First and foremost, it is equipped with an on/off switch as well as a voltage reading meter. And then, on the side, we have an Anderson connection, which is used to link it to your system; an Anderson connector to ring terminals is available for purchase as an optional accessory.

Portable Power USA
Full Review

I made the transition from lead acid batteries to a large battery. It was by far the finest decision I’ve ever made. We have a completely off-grid system; we purchased four of these batteries and are looking forward to completing the system. The pricing was a bit more than the other batteries we were considering, but they are produced in the United States. In my perspective, it was well worth the additional money.
