We produced an awesome 12 volt 100 Ah LiFePO4 battery pack
And we would like to tell you a little bit more technical details and our philosophy, what we kept in mind while designing it – our 12v 100ah lithium battery!
Durability and reliability of LiFePO4 batteries
Наш аккумулятор LiFePO4 can serve you 3000-5000 charge-discharge cycles. It will not lose its capacity. This is significantly better than most of aftermarket competitors, or premium lead-acid batteries, which often do not withstand even 500 cycles. This quality comes from our expertise and years on the market, we produce batteries since 2002~!
The built-in battery management system (BMS is also produced by us, because we do everything in house) protects the аккумулятор LiFePO4 from overcharging, overdischarging, and dangerous situations like short circuiting, and operating at too low or high temperatures. Our BMSs prevent damage.
Lightweight and compact
Наш 12 volt lithium battery is at least half the weight of lead-acid analogues of the same capacity, making it an ideal choice for portable applications (e.g. camping, boats, solar systems).
High energy density – with a power of 1280 Wh, it remains compact.
Energy efficiency and voltage stability
This battery provides a stable voltage of 12.8 V, even under high loads, which is ideal for devices sensitive to voltage fluctuations (solar systems, motors, electronics). High efficiency during charging and discharging (close to 95%) – this reduces energy loss.
Безопасность
LiFePO4 is safe, hands down. This type is famous for stability. In fact, it’s one of the most chemically stable lithium technologies. Practically it does not explode, doesn’t overheat in conditions where other lithium batteries would not survive.
Suitable for use in extreme conditions: low and high temperatures have less effect on its operation.
Environmentally friendly
One can’t find toxic substances in this lifepo4 battery. Nothing like lead or cadmium. The other great thing that makes this battery safe for the planet is that its production and disposal has less harm to the environment.
Versatility of application
It is ideal for Trolling motors, fishing, camping, solar systems and autonomous power supply. Electric scooters, home security systems, and even backup power in case of power outages.

Where is 100 amp hour lithium ion battery used?
From school we know, that 100 amps is a pretty strong current, so it’s clearly not for flashlights, on the other hand, it’s not for an electric helicopter
А аккумулятор 100 Ач is a powerful source of energy, but it’s really intended for devices with moderate to high consumption, where a long period of autonomous operation is needed, and not maximum power or super-lightness, as for drones or aviation.
The аккумулятор 100 Ач is used in high-drain systems. It is ideal for solar power and off-grid residential systems. It is often used in camping, RVs, and trailers. It is used for trolling motors, fish finders, and marine navigation. It is suitable for server backup, UPS, and home appliances. It is often used in electric scooters and powerful electric bicycles. It is used for fishing, hunting, and field conditions. It is suitable for medical devices such as oxygen concentrators. It is used in construction for lighting and emergency systems. It is durable, safe, and convenient for portable applications.
Let’s understand the design of this battery!
Этот LiFePO4 battery 12.8v 100ah has special marking: 4S17P.
The “4S17P” marking means that this battery is made up of multiple cylindrical cells, not just one.
4S (4 Series)
The cells are connected in series in 4 groups to achieve 12,8 В. Each LiFePO4 cell has a nominal voltage of 3.2V, and 4 such cells in series give 12,8 В (4 x 3.2V).
17P (17 Parallel)
-Each group has 17 cells connected in parallel to give a total capacity of 100Ah. Each cell has a smaller capacity (usually 5.8-6Ah for 32700FE).
So this battery is made up of 68 cells (4 series x 17 parallel).
Why is it done this way?
– Connecting cells in series increases the overall voltage.
– Connecting in parallel adds capacity, since the capacities of all parallel connected cells are summed.
– Using many cells improves the thermal stability and longevity of the 12.8 volt battery.
Each cell in this configuration is a cylinder (e.g. 32700 form factor, meaning 32mm in diameter and 70mm in length). 4S17P is a standard and efficient way to build a high-power 32700FE battery.
And this battery – is it a lithium deep cycle battery, or what class does it belong to?
Well, we need to figure this out.
Этот 100 Ah battery belongs to the lithium deep cycle class based on ЛиФеПО4. Deep cycle support for long charge-discharge cycles is indicated. ЛиФеПО4 chemistry provides stability, durability and safety of use. The 12.8V and 100Ah parameters are suitable for autonomous applications. The built-in BMS protects against overcharging, discharging, short circuit and overheating. It is ideal for solar systems and marine motors. The use is confirmed by CE, UL, FCC and ROHS certificates. Lighter and more efficient than traditional lead-acid batteries. Its declared resource is more than 2000 charge-discharge cycles. The 32700FE battery is compact, safe and environmentally friendly. Applicable for camping, fishing, electric scooters and security systems. Lithium deep cycle ones withstands high and low temperatures without loss of performance. Compatible with 12V systems for continuous power supply. An excellent choice for backup power in autonomous conditions. It saves weight, increases efficiency and durability of systems. Deep cycle batteries suitable for professional and domestic use. Provides stable operation under high load conditions. It is a reliable solution for many years of use in energy-intensive applications.
What is the difference between a lifep04 battery pack and a simple lifepo4 battery?
Why do we say “pack”?
А аккумуляторная батарея LiFePO4 and a аккумулятор LiFePO4 have their differences in their design and configuration.
LiFePO4 battery (cell)
- This is the basic element in which energy is accumulated. For example, a 18650 or 32700FE battery.
- Voltage of one cell is usually about 3.2 V – this is standard for LiFePO4 аккумуляторы.
- And we may find that one cell is often not equipped with a management system (BMS).
- And a LiFePO4 cell is only suitable for small devices or as part of a battery pack.
12 volt LiFePO4 battery pack
And if we talk about “packs” we mean “several items of the same kind”. And a 12v LiFePO4 pack also consists of several cells. Those клетки LiFePO4 can be connected in series (increasing voltage) or in parallel (increasing capacity).
For example, 4S17P means that the are 4 cells in each groups, and 17 groups are connected in parallel.
And another significant thing about 12 volt LiFePO4 packs is a Система управления батареями. BMS protects the pack from overcharging, short circuit, overheating and other hazards.
The cells in a pack are usually enclosed in a rugged case for safe use, it’s called Modular Design.
Used in electric vehicles, solar systems, boats, backup power supplies and other Complex Devices and applications.
For example, a pack can output 12.8 V и 100 Ач, while a cell is usually not that strong.
Why it is called a “pack”:
The word “pack” indicates that this is a complex device, not just a single cell. It includes:Several cells connected together. BMS for protection and management of this 12 volt lithium battery. Sometimes additional modules, such as cooling systems or housings for installation. “Pack” means a ready-made solution for the consumer, capable of operating in devices without additional modifications. Example of differences:
аккумулятор LiFePO4: Single cell 3.2V, 5Ah.
аккумулятор LiFePO4: Assembled module of 4 cells in series, outputting 12.8V, 100Ah, with BMS.
