Lifepo4 BMS 12v200ah Lithium Iron Battery Power Bank Energy Storage Batteries

Product Overview

The LifePO4 12V200AH energy storage battery is a type of lithium-ion energy storage battery using lithium iron phosphate as the cathode material. It is composed of multiple battery cells connected in series and parallel.Widely used in energy storage scenarios such as household energy storage systems, off-grid solar,wind power storage, backup power for communication base stations, and auxiliary power for RV/ships. It enables efficient storage and release of electrical energy, balancing power supply and demand.

Product Parameters

Voltage	12.8V
Size	522238218MM
Weight	21.5kg
Cycle Life	3000 Times
Design Life	10 years
Discharge Rate	0.2C-5C
Operation Temperature	-20-60°C

Key Features

The cathode uses lithium iron phosphate (LiFePO4) material, the anode is graphite, and the electrolyte is an organic carbonate system, featuring a stable crystal structure and strong chemical inertness.
The battery pack integrates a Battery Management System (BMS), which real-time monitors voltage, current, and temperature, providing protection against overcharging, over-discharging, short circuits, and overheating to ensure battery safety and longevity.
Deep Discharge Capability: Allows deep discharge to 20% remaining capacity (some products support 10%) while maintaining cycle stability, unlike traditional lead-acid batteries, where deep discharge significantly shortens lifespan.

Advantages

1.Ultra-Long Cycle Life

Cycle life reaches 6,000 cycles.This is 6-20 times that of traditional lead-acid batteries (300-500 cycles), reducing the frequency of replacements and lowering long-term costs.

2.High Safety

Lithium iron phosphate materials have excellent thermal stability, with a decomposition temperature above 800℃ (far higher than ternary lithium batteries’ 200-300℃). They rarely catch fire or explode under extreme conditions such as puncture, extrusion, short circuit, or overcharging, with no risk of heavy metal pollution.

3.Superior Energy Density and Efficiency

Energy density is approximately 140Wh/kg, lower than ternary lithium batteries but much higher than lead-acid batteries (30-40Wh/kg). For the same capacity, it is much lighter than the weight of lead-acid batteries of equal capacity.
High charge-discharge efficiency, with energy conversion efficiency exceeding 90% (compared to 70-80% for lead-acid batteries), reducing energy loss.

4.Balanced Low-Temperature and High-Temperature Performance

Better low-temperature capacity retention than lead-acid batteries: At -10℃, capacity retention is about 70-80% (lead-acid batteries may drop below 50%). It has no risk of thermal runaway at high temperatures, making it suitable for tropical regions or enclosed energy storage environments.

5.Low Self-Discharge and Long Storage Life

Monthly self-discharge rate is only 2% (vs. 15-30% for lead-acid batteries), with minimal power loss during idle periods. Even after 6 months of storage, remaining capacity can exceed 80%, eliminating the need for frequent recharging
