Product Features

High Safety LiFePO4 Core

Adopts high-purity lithium iron phosphate (LiFePO4) cathode material with intrinsic thermal stability—no thermal runaway risk even under short circuit, overcharge, or puncture. Integrated BMS (Battery Management System) provides 7-layer protection (overcharge, over-discharge, over-current, short circuit, over-temperature, under-temperature, balance protection) to ensure safe operation in critical power environments.

Ultra-Long Cycle Life

Boasts a cycle life of over 2000 times at 80% Depth of Discharge (DOD), retaining ≥80% of initial capacity—5x longer than traditional lead-acid batteries (300-500 cycles). Under shallow discharge (30% DOD), cycle life extends to 3000+ times, reducing replacement frequency and total cost of ownership (TCO) by up to 60% over 10 years.

FAQ

1. What are the key advantages of LiFePO4 battery over traditional lead-acid batteries?

Compared to lead-acid batteries, SY-Li Series LiFePO4 batteries offer 5x longer cycle life (2000+ vs. 300-500 cycles), 30% lighter weight (high energy density: 120Wh/kg), zero heavy metal pollution (eco-friendly), lower self-discharge rate (<3%/month vs. 10-15%/month), and no acid leakage risk. They also perform better in extreme temperatures and require minimal maintenance, reducing long-term costs.

2. What is the capacity retention and service life of the battery?

At 80% Depth of Discharge (DOD), the battery retains ≥80% of initial capacity after 2000 cycles; at 50% DOD, it retains ≥80% capacity after 2500 cycles; at 30% DOD (shallow discharge), cycle life exceeds 3000 cycles. Under normal operating conditions (room temperature, 50% DOD, regular charging), the service life is 8-10 years, compared to 2-3 years for lead-acid batteries.

3. What safety protection features does the integrated BMS provide?

The built-in BMS offers 7-layer comprehensive protection: (1) Overcharge protection (cut-off at 14.6V); (2) Over-discharge protection (cut-off at 10.0V); (3) Over-current protection (10A for 10Ah model, 20A for 20Ah model); (4) Short circuit protection (instant cut-off within 1ms); (5) Over-temperature protection (cut-off above 60°C); (6) Under-temperature protection (charging disabled below 0°C); (7) Cell balance protection (maintains voltage difference <20mV between cells).

4. What applications is the 12V LiFePO4 battery suitable for?

It is widely used in critical power and energy storage scenarios, including: UPS backup power systems (data centers, server rooms), communication base stations, off-grid solar/wind energy storage, emergency lighting, medical equipment backup, RV/camping power supplies, and industrial control systems. It is compatible with most standard 12V power devices and UPS brands.

5. What are the charging requirements and maintenance precautions?

Charging requirements: Use a LiFePO4-specific charger (constant current-constant voltage, CC-CV) with charging voltage 14.2-14.6V and charging current ≤0.5C (e.g., 5A for 10Ah battery). Avoid using lead-acid chargers (overcharging risk). Maintenance precautions: (1) Store in a dry, ventilated environment (10-30°C) if unused for long periods; (2) Recharge to 50-70% capacity every 3 months to prevent deep discharge; (3) Avoid short circuit, puncture, or exposure to open flame; (4) No need for water addition or acid level checks (maintenance-free).

6. Can multiple batteries be connected in series or parallel for higher voltage/capacity?

Yes. For higher voltage: Connect up to 4 batteries in series (12V×4=48V) to match UPS or inverter requirements. For higher capacity: Connect up to 4 batteries in parallel (e.g., two 10Ah batteries in parallel = 20Ah capacity). Note: Ensure all batteries are from the same model, same batch, and have similar voltage (difference <0.2V) before connection. Use dedicated series/parallel connectors and avoid overloading the total current.
