  • From Supplier to Trusted Brand: Siekon, a well-established supplier of electric vehicle battery components operates a factory spanning over 12000 ㎡ and holds more than 70 patented technologies. The company has now introduced its sub-brand -- Siekon Energy, specializing in LiFePO4 batteries and energy storage solutions. Siekon Energy possesses a mature industrial chain for manufacturing from cell sorting and component assembly to battery testing and transportation, ensuring uncompromising quality at every stage.

  • Longer Lifetime: Unlike lead-acid batteries that typically last for only 300-400 cycles, our lithium-iron batteries are manufactured with grade-A lithium iron phosphate cells offering higher energy density, more stable performance, and greater power output. They can reach up to 5000 cycles at 100% DOD while maintaining an impressive capacity retention of 80% after 5000 cycles.

  • Lighter Weight & Compact Size: The Siekon 100Ah LiFePO4 12 Volt Battery is 64% lighter and 10% smaller than a Lead-Acid battery. This makes it more convenient to carry, with various mounting options, its compact size also facilitates easier placement and connection. The lifepo4 battery also eliminates the risk of leakage, and no maintenance is needed, for increased stability and safety.

  • Next-Gen BMS Upgrade: Our Siekon Energy's 100Ah LiFePO4 12 Volt Battery comes equipped with an upgraded BMS featuring pulse equalization as well as low-temp protection at 5℉. It also effectively prevents overcharging, over-discharging excessive current flow, or short circuits to ensure safe use and stable performance.

  • Wide Applications: Siekon Energy's 100Ah LiFePO4 lithium 12 Volt battery finds applications in RVs, Caravans, Marine, Golf Carts, Trolling motors, Tool trailers, Backup power supplies, Solar Power Systems, Off-Grid, etc., supporting up to four series connections and four parallel connections reaching up to an impressive capacity of 20.48KWh (51.2V 400Ah).

  • Exceptional Service: Siekon offers precise battery instructions and Q&A through a responsive and professional customer support hotline and email address. For any product-related issues or questions, please feel free to contact us.

What are the housing materials of this battery?

We use ABS (Flame Retardant Plastic) as the housing material.

What is the protection class of this battery?


What is the warranty period for this battery?

We offer a five-year warranty.

How many bolts does this battery come with?

We provide four M8 bolts.

Does this battery's terminal come with insulation covers and insulation caps?

Yes, we provide two insulation covers and two insulation caps.

Does this battery come with a carrying strap?

Yes, we provide a detachable carrying strap.

Which manufacturer the cells are sourced from?

We use EVE cells, ranked in the top 10 in the power industry.

When was the production date of the cells?

2024.01- 2024.03

What is the capacity of the cells?

The actual capacity of these cells is slightly larger than the rated capacity of 100Ah.

Which manufacturer the BMS are sourced from?

We use JBD‘s BMS.

What are the specifications of the BMS cables for this battery?

The BMS positive terminal uses a 4 AWG cable, and the negative terminal uses two 7 AWG cables, all of which are UL certified.

Does the BMS have a low-temperature protection function?

Yes, the battery will automatically cut off the current when the temperature drops below -15 ℃.

How to restart the battery after a low-temperature cutoff?

Yes, the battery will automatically cut off the current when the temperature exceeds 55 ℃.

How to restart the battery after a high-temperature cutoff?

The battery can be restarted when the temperature recovers to within 50 ℃.

How much is the charging rate of this battery?

Recommended charging rate: 0.2C (20A), which effectively ensures the battery's lifespan; Maximum continuous charging rate: 1C (100A), which can quickly charge the battery (approximately 1 hour).

Is the internal structure of this battery safe enough?

The internal structure of the battery is safe. The battery cells are placed sideways without blocking the explosion-proof valve. Laser welding is used for the battery cell terminals for a more secure connection. Foam is placed around cells to facilitate secure fixation and prevent impacts. There is 1mm foam between each cell to prevent expansion and compression, and an insulation board is installed between the battery cells and the BMS to protect the BMS from interference or short circuits.

How many series connections can this battery support?

This battery supports 2 to 4 series connections (up to 4*4 series-parallel connections, with series-parallel operations performed when fully charged).
