Why the TopBand 12V Lithium Battery Stands Apart

Engineered for Extreme Environments

Don't let your environment dictate your power. This battery is built to thrive where others fail. The rugged, flame-retardant (UL94V-0) ABS plastic case is fully sealed to an IP67 waterproof and dustproof rating, making it impervious to water, dirt, and vibration. A built-in safety valve provides an extra layer of protection under extreme conditions.

Intelligent Power for Cold Climates

Standard lithium batteries can't charge in freezing temperatures. The TopBand battery features an integrated low-temperature heating system. The intelligent Battery Management System (BMS) automatically uses charger power to warm the cells before charging, allowing for reliable performance and safe charging in temperatures as low as -20°C (-4°F).

Unmatched Intelligence & Control

Your battery's status should never be a mystery. With Smart Bluetooth connectivity, you can monitor state of charge (SoC), voltage, current, and cell health directly from your smartphone. The powerful BMS also supports CAN/RS485 communication, allowing for seamless, closed-loop integration with leading inverters like Victron (via Cerbo GX) for a truly unified and smart power system. Plus, firmware can be updated remotely via Bluetooth (OTA), ensuring your battery is always running the latest software.

Designed for Longevity & Serviceability

This isn't a disposable battery; it's a long-term investment. With a design life of over 15 years and an incredible >6,000 cycle life at 80% Depth of Discharge (DOD), it outlasts traditional lead-acid batteries by more than 10 times. Unlike sealed competitors, the case is assembled with screws, making it fully serviceable and maintainable for a truly extended lifespan. An integrated power button allows you to cut the battery off completely, reducing self-discharge during storage and shipping.

Flexible System Expansion

Your power system can grow with your needs. The advanced BMS in the TopBand battery provides incredible flexibility:

• Connect up to 4 batteries in series to create a high-voltage 24V, 36V, or 48V system.
• Connect up to 16 batteries in parallel to build a massive 12V power bank (e.g., 16 x 100Ah = 1600Ah).
• Combine series and parallel connections (e.g., 4S4P) for complex, high-capacity systems.

Certified Safety & Reliability

Your safety is paramount. The TopBand battery is one of the most rigorously tested and certified batteries on the market, giving you ultimate peace of mind.

• Pack Certifications: UL1973, UN38.3, IEC62619, CE, E-mark
• Cell Certifications: UL1973, UL9540A, UN38.3, IEC62133

These certifications ensure the highest standards of safety against thermal runaway, short circuits, and other potential hazards.
