BigBattery.com was founded to provide people with a more affordable and sustainable energy solution. Many people may believe solar equipment is unattainable due to high up-front costs, but BigBattery.com believes it can offer battery solutions at affordable rates. All battery systems sold through BigBattery.com are lithium-ion battery banks made of high quality cells. 

Product affordability is what truly sets the company apart from the rest of the industry. Instead of needing to take out a loan or leasing solar equipment, customers can work with BigBattery.com which offers high quality solutions at discounted rates that can provide immediate savings in some cases. 

The BigBattery.com platform has partnered with a number of organizations that work to advance the causes that sustainable energy can provide worldwide. The company is a contributing member of the following groups: Energy Storage Association (ESA), Solar Energy Industries Association (SEIA), and the Golf Course Superintendents Association of America (GCSAA) due to its gold cart solutions.

The Good

  • Off Grid Solutions
  • Mobile Equipment
  • Accessories Offered
  • Warranty Protection

Off Grid Solutions

Not many people think about the freedom associated with off-grid living. Residential property owners looking to access this level of freedom will find solutions through BigBattery.com. All battery LiFeP04 systems sold through BigBattery.com will include the following components:

  • Meets needs of all homes and sizes
  • Easy to install 
  • Scalable equipment
  • Powers all appliances
  • Lowers electric bills
  • Requires no maintenance

Clients looking to support their solar panel system will find an affordable solution through BigBattery.com. 

Mobile Equipment

Property owners are not the only ones who can benefit from solar solutions and energy independence. As the rise in RV living continues to sweep the country, many are turning to alternative battery solutions to power their vehicles. Through BigBattery.com, clients can purchase batteries for their RVs, as well as vans and golf carts.

Accessories Offered

In conjunction with its comprehensive sales of lithium-ion batteries are a number of compatible accessories. All accessories sold through BigBattery.com are designed to fit all homes and mobile needs to help power appliances and lower electric bills. Available accessories include inverters, chargers, cables, and connectors.

Not only does BigBattery.com sell direct solar accessories, all of these products can be purchased at an affordable and discounted rate. Traditional solar clients are charged substantially more for the same equipment. 

Warranty Protection

Even though most solar manufacturers offer a 25-year warranty, there is a reason that the BigBattery.com 10-year warranty is worth highlighting. The main reason is because the BigBattery.com warranty is a true 10-year full repair/replacement warranty. Most solar clients will find that there is less help with a 25-year equipment warranty than the true 10-year protection BigBattery.com offers. The warranty includes:

  • All battery packs covered
  • Automated warranty registration
  • Free repair and replacement
  • Full lifetime tech support and customer service

30-Day Money-Back Guarantee

With most warranties, proof of malfunction will be required and fault will need to be assigned prior to any repair or replacement work being done. It also generally takes substantial time for the repair or replacement parts to be delivered and installed. That is not the case with BigBattery.com as the company will immediately ship out necessary parts.

The Bad

  • No Solar Panels Sold
  • DIY Installation

No Solar Panels Sold

Despite offering solar accessories like inverters and chargers, there are no solar panels sold through BigBattery.com. This is not necessarily a concern for those with mobile power needs, but for those utilizing BigBattery.com for residential needs, this can be concerning. A solar system will need to be installed previously in order for the battery pack to be connected.

Clients who utilize a solar company that only installs solar systems and does not offer battery/storage solutions can benefit from this. Otherwise, it makes more sense for a residential client to go through a solar provider that offers all equipment needs. 

DIY Installation

While BigBattery.com does provide instructions for installation, professional installation is not available. Clients will have the equipment mailed directly to them and it is up to them to connect all system parts correctly in order for operation.

For mobile solutions, connecting the battery system for power is not as concerning, but it is a worry for residential customers. Most residential solar providers offer professional installation, but all equipment sold through BigBattery.com requires DIY installation efforts.

The Bottom Line

BigBattery.com provides off grid solar battery solutions in an effort to provide clients with a more affordable way to become energy independent. While most products are geared towards mobile solar power needs, there are residential and business solutions as well. The off grid residential solutions will power homes and require no maintenance.

There are also battery and solar solutions for mobile equipment like RVs, golf carts, and vans. This is an excellent option for those that will be on the road for a long period of time and will need an independent power source.

In addition to selling battery systems, BigBattery.com also offers inverters, chargers, cables, and connectors. All equipment sold through BigBattery.com is backed by a 10-year comprehensive warranty. 

While BigBattery.com has a number of off grid battery solutions, there are limitations to what the platform sells. There are no solar panels available for sale through BigBattery.com, strictly batteries and inverters. All installation is DIY; no professional installation is available through BigBattery.com.

Those looking to be more energy independent and searching for affordable solar battery solutions will likely find a number of options to choose from with BigBattery.com. Those more interested in the traditional solar system will have to go elsewhere for service.

Big Battery Frequently Asked Questions

How many years will my battery last?

Lithium Iron Phosphate (LifePO4) batteries can be cycled from 3,000 to 7,000 times. If you cycle the battery daily with an 80 percent Depth of Discharge (DoD), then you can get up to 10 years or more of use from your battery.

Can your batteries be used in series?

The company no longer offer batteries for use in series.

Do Big Battery's batteries have a thermal management system?

All the company's batteries have a thermal management system that is controlled by the BMS (Battery Management System). This thermal management system will not only prevent the battery from being used if the temperature is too high, but also if the temperature is too low.

Can I use my OEM's charger?

No. Lead acid battery chargers charge at different currents and voltages than lithium batteries. Using your OEM charger can damage your battery cells and void your battery’s 10-year warranty. The company has several chargers optimized for and calibrated to every battery it sells.

Why does the voltage drop when unplugging the charger?

The voltage drop that you experienced is called the “bubble voltage” and is perfectly normal for lithium batteries. LiFePO4 batteries behave differently than other battery chemistries. The Voltage vs. Capacity is not linear. For example, if you have a voltage between 13.3–14.6 or 26.6–29.2 or 53.6–58.4, you will have more than 99 percent of the capacity. This essentially means that “Bubble Voltage” contains less than 1 percent of the entire capacity, and the drop when a load is placed is instant.

Can I leave my batteries outside?

No. The company's batteries are not marine rated or weatherproof, so leaving them out under the sun all day or in the rain can damage the batteries. This type of damage is not covered under the 10-year warranty.

Is BigBattery compatible with all inverters and charge controllers?

The company's batteries work great with almost all inverter/charge controller brands. The only brand not compatible is RENOGY. Please confirm that your inverter can be set to the operating parameters of the battery you’re interested in before purchasing. Parameters can be found as a downloadable PDF spec sheet on every battery's product page.

How do I install my battery?

All batteries come with a ring terminal cable that can be used to connect your battery to your inverter, busbar, or the rest of your system. Big Battery also sells a parallel busbar that can be used in tandem with the included ring terminals to parallel multiple batteries together.

Does Big Battery sell used/surplus batteries?

In the past BigBattery sold refurbished batteries, such as solar batteries made from recertified Leaf modules. As of the year 2020, all batteries sold are new, never previously cycled batteries that come with a complimentary 10-year warranty.

How long before my order ships?

It can take anywhere from a week to no more than two weeks for shipment. This time allows the company to assemble, test, and inspect each battery prior to shipping.
