About Fogstar Batteries
Fogstar was founded in 2016 in order to fill a gap in the UK market for lithium batteries. Lithium batteries were becoming more popular but buyers in the UK had a limited number of suppliers and quality control wasn’t always what it should be. At the time, counterfeit lithium cells claiming to be from well-known brands like Sony and Panasonic were common. These fake cells could be dangerous because they often didn’t meet the specifications of the genuine products they were imitating.
The founders of Fogstar, took note of the difficulties faced by UK buyers and decided to revolutionise the marketplace. Fogstar’s simple mission was to provide UK and EU buyers with an affordable and reliable supply of genuine lithium batteries.
From humble beginnings supplying genuine branded cylindrical cells for consumer electronics such as flashlights, the business has grown to offer the high-quality prismatic Lithium Ferro Phosphate (LFP) cells, the same type used in the automotive industry. Fogstar also produces its own range of leisure batteries and domestic home energy storage solutions.
Since its early days Fogstar has won multiple awards for their various product lines and is widely regarded as one of the most trusted lithium battery vendors in the UK. Buying from Fogstar couldn’t be simpler, thanks to their UK based sales and customer support team. They also maintain large stocks of products at their Redditch based headquarters.
The Fogstar Battery Range UK
Starting with the smallest batteries on offer, Fogstar offers a range of cylindrical lithium battery cells in 18650, 18350 and 21700 sizes, sourced from leading manufacturers such as EVE, Molicell, Sanyo, and of course, Fogstar themselves.
Moving up in size, Fogstar provides LFP prismatic cells, the same type used in the automotive industry. These 3.2V cells can be combined to form 12V, 24V, or 48V battery packs for leisure or domestic use. Fogstar currently supplies cells from EVE and Comex, and offers a variety of Battery Management Systems (BMS) depending on the size of battery and intended use.
Next in the lineup are Fogstar’s leisure batteries. Available in 12V (100Ah–628Ah), 24V (230Ah–280Ah), and even a 48V 125Ah pack. These batteries are designed primarily for recreational vehicles and marine applications. Its safe to say that Fogstar have incredible range and experience when it comes down to energy storage.
Fogstar Solar Batteries
Finally we come to Fogstar’s range of Solar Batteries. This is the part of their business that we at Deege Solar have the most experience with, and it’s the range that has truly disrupted the home energy storage market in the UK.
Fogstar 16.1kWh 48V PACE BMS Battery
The most popular option in this range is the Fogstar 16.1kWh 48V PACE BMS battery. With an 80% Depth of Discharge (DoD), this powerful unit delivers 12.88kWh of usable storage for just £1,999.99, which is outstanding value for money. The battery also comes with a 10-year warranty and an 8,000-cycle life, putting it in line with the best solar batteries on the market.
Made up of 16 premium Grade A EVE LiFePO4 cells, weighing an incredible 140kg, this battery’s weight is a true reflection of its robust construction and long-lasting durability. Despite its weight, the battery can still be wall mounted, enabling you to free up valuable floor space, and is extremely easy to manoeuvre thanks to its integrated wheels. This practical design is a real advantage for homeowners who may need to relocate the battery during installation or maintenance.
On top of this, this Fogstar battery also features an intelligent internal heating system, ensuring optimal performance in temperatures as low as -20°C. Up to 15 units can be installed in parallel, providing an incredibly scalable and flexible solution for those with larger storage needs. It is no wonder that the Evening Standard newspaper awarded this battery the “Best for high-usage households” award in February 2025.
Fogstar 16.1kWh 48V Seplos BMS Battery
For installations in a heated area of the home, Fogstar offers a 16.1kWh battery fitted with a Seplos BMS. This model is similar to the PACE battery above but does not include the intelligent heating system. This Fogstar battery is much taller, and thinner, weighing around 20kg less, and is designed to be floor-standing. Up to 16 units can be connected together for up to 257.6 kWh of storage, and the battery can simply be wheeled into place for convenience. While it comes with only 6-year warranty, it still offers the same 8,000-cycle life and 10 years of customer support. With a reduced price of £1,749.99, this battery is an attractive option for those looking to maximise on payback quickly.
For those with the technical ability to assemble their own battery and looking to save further, the Seplos battery is also available as a DIY kit for £1,599.99. Another version, the “Mason” DIY kit, is priced at £1,539.83 and features a more basic, functional design resembling flight cases used to transport equipment to and from concerts.
For larger storage needs, the Seplos battery is also available in a 32kWh version for £3,399.99. This high-capacity unit is a true heavyweight, weighing 233kg, so careful planning is required to position it safely.
Fogstar Stackable 5.12kWh Battery
Customers can choose the standard 5.12kWh module for £729.99, or upgrade to the 5.12kWh Server Rack module with an internal heating system for £899.99. Both models feature an 80% Depth of Discharge and a 6-year warranty, but the cycle life differs. The non-heated module offers 6,000 cycles, while the heated Server Rack module provides 4,000 cycles. The Server Rack modules can also be installed in Fogstar’s IP65 outdoor cabinet, offering a robust solution for outdoor battery storage.

Conclusion: Fogstar Battery Review
If you’re wondering “are Fogstar batteries any good?”, the short answer is yes, especially if you’re looking for a high-quality home battery storage solution designed for indoor installation. From a price-per-kilowatt perspective, Fogstar batteries offer exceptional value, and when you compare their warranty and cycle life to competitors, it’s clear that Fogstar isn’t just competing at the affordable end of the market. Their coverage rivals that of many premium solar battery brands, but at a fraction of the cost.
Even if you are seeking an outdoor solar battery installation, the heated Fogstar PACE battery performs brilliantly when housed in a simple garden storage unit, keeping it protected even through the coldest UK winters.
In this Fogstar battery review, it’s also worth noting that Fogstar caters to more than just home energy storage. Their extensive leisure battery range supports installations on recreational vehicles and boats, which demonstrates their depth of battery expertise. This year alone, after exhibiting their home battery lineup at Solar & Storage 2025, Fogstar showcased their leisure range at the National Motorhome and Caravan Show, reinforcing their commitment to quality and versatility.
Overall, Fogstar batteries make sense for a wide variety of installations. From small electronic projects powered by cylindrical cells to leisure batteries for installation that are on the go, and finally home battery storage systems that deliver top-tier performance without the premium price tag. The only situation where a Fogstar home battery might not fit perfectly is when outdoor space is too limited for even a small storage unit. But with Fogstar’s innovation, a little bird tells us even that gap may soon be filled.
