12V LiFePO4 Slim Case Battery - 200Ah by Enerdrive B-TEC
Meet the Enerdrive B-TEC LiFePO4 12V 200Ah Slim Case Battery—the compact, high-capacity power core built for off-grid, RV, marine, and mobile setups. Its slim profile fits tight spaces without sacrificing reliability or capacity.
- Slim, space-saving dimensions: 530 mm wide × 600 mm high × 83 mm deep, delivering 200Ah usable capacity in a footprint that fits narrow engine bays, compact vans, and small boat compartments.
- One-end connectivity: All connection points, including RJ45 remote comms ports and the Reset Port, are located on a single end to simplify wiring, routing, and service access.
- Remote reset: Reset button mounted away from the battery for cleaner seals and easier maintenance with fewer water ingress concerns.
- IP52-rated enclosure: Rugged metal housing with blind bolts and rubber seals minimizes water ingress in challenging environments.
- Smart monitoring: Wireless Battery Monitoring Technology lets you track capacity, voltage, current, SOC, SOH, temperatures, cycles, alarms, and events from an Android or iOS device.
- LiFePO4 chemistry: Nominal 12.8V, 200Ah capacity, and endurance of ≥2000 cycles at 80% DoD under controlled conditions for long-term reliability.
- Smart charging compatibility: Uses a lithium-profile charger; standard charging voltage 14.20–14.60V, float 13.50–13.80V, with a maximum charge current up to 150A at 25°C for 30 minutes (operable 0–45°C).
- Real-world operating range: Discharge temperature range −20°C to 60°C; output voltage 11.0–14.60V; maximum discharge current 250A for 30 minutes; 450A pulse for 1 second.
- Designed for practical use: Perfect for off-grid solar, camper vans, yachts, remote backups, and any application where space is at a premium but dependable energy storage matters.
The B-TEC Slim Case battery is engineered for longevity, easy installation, and intelligent monitoring. Its compact form, durable enclosure, and smartphone-driven insights help you manage power more efficiently, reduce maintenance, and scale energy systems without bulky packs. Ideal for tight-space deployments where reliable 12V LiFePO4 energy storage makes the difference between quiet, self-reliant days and constant power anxiety.
