Product Description



Koyosonic LP Series: Premium 12V LiFePO4 Battery Solutions
The Ultimate Drop-in Replacement for AGM & Gel Batteries
Product Overview
Upgrade your power systems with the Koyosonic LP Series, the next generation of 12V Lithium Iron Phosphate (LiFePO4) batteries. Engineered as a seamless "drop-in" replacement for traditional lead-acid, AGM, and Gel batteries, the LP Series offers superior energy density, safety, and longevity.
Designed for versatility, these batteries function exceptionally as standalone 12V units or can be assembled in series to create powerful 24V, 36V, or 48V systems. Whether for renewable energy storage, marine applications, or motive power, the LP Series delivers consistent, high-performance energy when you need it most.
Key Advantages & Features
1. Exceptional Cycle Life & ROI
-
Longevity: Delivers up to 2,000 - 5,000+ cycles (depending on DoD), compared to just 300-500 cycles for traditional lead-acid batteries.
-
Cost Efficiency: Although the initial investment is higher, the cost per cycle is significantly lower, providing a massive return on investment over the product's 10+ year design life.
2. Intelligent BMS Protection (Battery Management System)
-
Safety First: Built-in sophisticated BMS monitors cell health in real-time.
-
Comprehensive Protection: Automatically protects against overcharging, over-discharging, over-current, short circuits, and extreme temperatures, ensuring system safety and preventing premature failure.
3. 100% Usable Capacity (High Energy Density)
-
Deep Discharge: Unlike lead-acid batteries that are limited to 50% depth of discharge (DoD) to prevent damage, Koyosonic LiFePO4 batteries allow for 100% usable capacity.
-
Constant Power: Maintains a stable voltage curve throughout the discharge cycle, ensuring your appliances run efficiently until the battery is empty.
4. Ultra-Lightweight Design
-
Weight Reduction: Weighs approximately 1/3 to 1/2 of a comparable lead-acid battery.
-
Benefit: Crucial for RVs, Marine vessels, and portable applications where reducing payload improves fuel efficiency and handling.
5. Fast Charging & Ultra-Low Self-Discharge
-
Rapid Recovery: Capable of accepting high charge currents (1C), drastically reducing downtime.
-
Storage Ready: With a self-discharge rate of <3% per month, the LP Series is perfect for seasonal vehicles (Boats/RVs) that sit idle for long periods.
6. Flexible System Scalability
-
Series & Parallel: Engineered to be connected in series (up to 4 units for 48V) or parallel to increase capacity, offering a customized solution for specific voltage and amp-hour requirements.
7. Easy "Drop-in" Installation
-
Standard Dimensions: Designed with standard BCI group sizes to fit existing battery boxes. No complex rewiring or specialized tools required for installation.
8. Eco-Friendly & Green Energy
-
Non-Toxic: Free from rare earth metals, heavy metals (lead/cadmium), and corrosive acids.
-
Clean Tech: The safest lithium chemistry available, making it the responsible choice for modern energy storage.

As one of professional manufacturers, we have been devoted to research and development, manufacture and market to lead users to have right batteries for right power system.
Our Lead-acid batteries include AGM batteries and SLI batteries. AGM batteries are also called as VRLA-AGM batteries, mainly including NP general batteries, NPC deep-cycle batteries, NPH High-rate batteries, NPL long-life batteries, NPF front-terminal batteries, NPM motive-power batteries, NPG/NPCG/NPMG/NPFG pure gel batteries, NPS solar-power batteries, CB Lead Carbon Batteries, LC Lead Crystal Batteries, LFP LiFePO4 Batteries, and OPzV & OPzS tubular batteries. For SLI batteries, we mainly have Car batteries and Motorcycle batteries.
In 2015, we started to produce Li-ion battery pack which mainly includes LiFePO4 battery pack to replace AGM batteries, Powerwall batteries and Powerrack batteries. OEM and ODM is welcome.
We have introduced advanced production and test equipment to produce lead acid batteries and so we can do much better in the battery fields as we are very strict in production management and we have first-class technology and unique directions for the batteries. We have more than 600 staff members among whom there are more than 50 professional technicians. This ensures our products are much better in performance and reliable in quality. We have gotten production license from National Quality and Technology Supervision Bureau and also we have gotten some international certificates such as UL, CE, TLC and ISO9001 & ISO14001.
In market, we mainly produce batteries against OEM and ODM for some well-known international companies. Nowadays, we are going to market our own brand "Koyosonic" and welcome customers to visit us for more negotiation in our business cooperation.
