Stackable LifePO4 Battery Series
Saftec stackable batteries are modular tower-type LiFePO₄ systems that expand from 10 kWh to over 20 kWh per stack. They combine advanced BMS protection with seamless inverter communication for hybrid solar, backup, and microgrid applications.
Designed with high energy density (≈ 21 kWh per tower) and lightweight aluminum housing, these batteries simplify installation and maintenance compared with cabinet or rack systems.

Applications of Stackable Batteries
- Residential Solar ESS: Modular 5–25 kWh systems ideal for homes needing long-term backup and energy shifting.
- Commercial & Industrial: Expandable towers power small factories, telecom stations, and EV-charging microgrids.
- Off-Grid & Hybrid Systems: Stable 48 V/51.2 V configurations integrate smoothly with hybrid inverters for islanded systems.
- Agricultural & Remote Projects: Reduce diesel reliance in farms, resorts, and island communities.
Why Choose Saftec Battery?
Saftec engineers and manufactures its own LiFePO4 modules using Grade-A prismatic cells and BMS with 20+ protections.
We support OEM/ODM customization—voltage, housing, connectors, or BMS protocol—to match mainstream inverters (Growatt, Deye, GoodWe, Sofar).
Each unit passes vibration, drop, and thermal tests before export, ensuring field reliability and smooth customs clearance.
Inverter Compatibility
Saftec batteries feature smart BMS with CAN/RS485, ensuring smooth integration with leading inverter brands such as Growatt, GoodWe, Victron, Deye, and Fronius.
Saftec Battery Certificates
Saftec 48V/51.2V batteries are tested to UN38.3 and supplied with CE, IEC62133, and MSDS certifications, ensuring compliance for both sea and air transport. Each module is built with safe LiFePO4 chemistry and a smart BMS, delivering reliable backup power for telecom, data centers, and UPS applications.
The Process Flow of Ordering From Saftec
Importing batteries can be complex — we make it simple. Here’s how your order moves from inquiry to delivery:
Step 1: Inquiry & Solution
Send us your requirements. Our engineers analyze your project and recommend the right 48V/51.2V rack battery configuration within 24 hours.
Step 2: Sample Production & Testing (~5 days)
We build your sample using brand new LiFePO4 cells. Each pack is tested for safety, capacity, and communication before shipping.
Step 3: Sample Delivery (~30–40 days by DDP air/sea)
Samples are packed with DG labeling and UN38.3 documents for smooth clearance. Tracking info is shared throughout transit.
Step 4: Bulk Production (~25–30 days)
Once the sample is approved, mass production begins. Saftec follows strict QC standards and reports progress at each stage.
Step 5: Bulk Shipping (~30–40 days by sea freight)
We palletize and secure each carton for long-distance transport. All export paperwork is prepared for fast customs release.

Common Pitfalls When Purchasing Stackable Batteries
When sourcing energy storage products, it’s important to look beyond the price tag. At Saftec, we help buyers avoid common mistakes that can lead to costly issues later.
Unverified cell sourcing — many suppliers use mixed-grade cells, causing early capacity loss after 800–1000 cycles.
No BMS communication — without proper CAN mapping, inverters show SOC errors and charging stops.
Incomplete certification — missing UN38.3 reports often delays customs or air transport.
Overstated capacity — marketing labels 25 kWh but real usable energy is < 80 % DoD.
Saftec prevents these issues by validating every module under real-world ESS conditions before delivery.
