Big Battery 48V 2X RHINO KIT – LiFePO4 – 552Ah – 28kWh
WORLD’S THINNEST WALL MOUNTED BATTERY! BigBattery’s 48V 28 kWh LiFePO4 2x RHINO Kit is here and if you’re looking to create a massive solar or off-grid system, the RHINO Kit is your answer.
A single RHINO unit is not only a mere 4 inches thick, allowing you to discreetly install the unit wherever you need in your home or garage, but beats the Tesla Powerwall 2 in every single category! The RHINO has 500 more watt-hours of capacity, has a 200% greater lifespan, utilizes LFP, the safer chemistry compared to NMC in the Powerwall 2, and is significantly more cost-effective. Did we mention that it’s completely fireproof? That’s right, the RHINO utilizes cutting edge LFP cells capable of being fully punctured without releasing toxic fumes or catching on fire.
The 2x RHINO Kit comes with a floor stand which holds both RHINOs securely in place. This stand is equipped with heavy-duty caster wheels for easy transportation and each RHINO unit comes with an LED Smart Display so you can always monitor the health and status of your RHINOs. If you’re looking for a safe, reliable, and high capacity solution for your off-grid or solar applications, pick up your RHINO Kit today!

Cancellations of Custom Orders:
Custom or made-to-order products cannot be cancelled or refunded, as these products are specifically produced for your order. These units are custom made according to your specifications or created once you place your order. Your warranty ensures that you receive a fully functional and operational product. If you are unsure whether your order is custom or made-to-order, please message or call us for clarification. All sales are final for custom-made and made-to-order products.
Refunds and Returns:
If you need to exchange your product, you may do so, but please note that you, as the customer, are responsible for any shipping costs incurred during the returns and exchange process. Please be aware that not all orders are eligible for return once they have shipped, as we source our products directly from manufacturers. Therefore, if the manufacturer does not permit us to return a product, we are unable to offer you a return. This policy may vary on a case-by-case basis, so please reach out to us for specific information regarding your brand and/or product. Due to the increasing costs of LTL/freight shipping, outright returns will be subject to a 25% cancellation fee plus return shipping costs. However, if you are replacing the product with something else, we may be able to assist with covering some of the costs, depending on the product.
Shipping Times:
We strive to deliver your order as quickly as possible. Estimated shipping times provided on the product pages are based on information from our suppliers and freight companies, but these estimates may change or vary without notice due to factors such as supply chain issues, delays in steel mills, manufacturing delays due to mills, high demand on shipping, factory/warehouse and dock workers, and so on).
Order delays are beyond The Home Upgrade's control and have proven to be unavoidable. We understand that this may be frustrating, and we kindly ask for your patience and understanding during these challenging times. We appreciate your business and value your patience.
