DIY Safety Guidelines
- Always wear safety glasses and gloves when working with electrical equipment
- Ensure cells are within operating temperature range before use
- Do not use punctured, damaged, or leaking cells
- Provide adequate protection during assembly and use
- Dispose of properly at recycling facilities
- Do not submerge in water or expose to direct heat/fire
- Avoid harsh impacts and extreme vibrations
Packaging
Protected with foam inserts and UN-certified cartons for safe transportation.
Critical Safety Advice
- Do not submerge battery in water
- Do not reverse positive and negative terminals
- Do not disassemble, dispose in fire, heat, or short circuit
- Do not expose to direct sunlight for extended periods
- Keep away from children
- Do not short circuit under any circumstances
- Fully charge new batteries before first use
- Do not open battery safety valve
- Do not violently tighten terminal screws
- Do not mix different battery brands, capacities, or conditions
Important Notes
Check all battery voltages and internal resistance before DIY assembly. Ensure proper balancing. Basic electronics knowledge required for assembly. Some cells may have minor scratches from transportation - these do not affect performance.

Frequently Asked Questions
Q1: Are busbars and screws included and free?
Yes, we include busbar connectors and screws free with battery purchase.
Q2: What is the lifecycle of the battery?
Typical lifespan is 5-8 years or 2000-5000 charge cycles, depending on depth of discharge, current rate, temperature, and balancing system usage.
Q3: Can I use a normal solar controller with LiFePO4 batteries?
We recommend using LiFePO4-specific solar controllers. Lead acid controllers may damage the PCB protection circuit over time with constant pulse currents.
Q4: Do you offer reseller pricing?
Yes, we support partners who share our vision for clean energy. Contact us for reseller pricing and support.
Q5: Why can't I buy batteries directly from your store?
This typically occurs when we cannot provide accurate logistics pricing for your country. Please contact us directly for purchasing.
Q6: Why is there no tracking update for weeks?
This is normal for international shipping. Tracking updates begin when packages arrive in your country. No tracking is available during transit.
Q7: Are the cells balanced before shipment?
Yes, we match and balance all cells to ensure consistent internal resistance, voltage, and capacity before delivery.
