Features
Details from the SOK Battery SK48V100N Amazon listing:
- 【Ev-grade A+ Cells & 6,000+ Cycle Lifespan For Long】: Power high-demand appliances (air conditioners, microwaves, essentials) with confidence thanks to premium 102Ah EV-grade LiFePO4 cells, delivering 5.12 kWh base capacity and 5120W maximum output. Boasting 6,000+ charge cycles (at 80% Depth of Discharge) and a 10-year typical lifespan, this maintenance-free battery eliminates frequent replacements, cutting long-term costs while providing consistent, robust power for all your off-grid needs
- 【Intelligent Cold-weather Heating】: Operate reliably in extreme temps (-4°F to 149°F) with a rugged full-metal casing that resists bumps and vibrations—ideal for RVs and remote cabins. Charge confidently down to -4°F/-20℃: the built-in self-heating system activates automatically below 32°F/0℃, prioritizing heating with >10A current until internal temp reaches 41°F/5℃, then switching to full charging. LiFePO4 chemistry eliminates leakage and thermal runaway risks for year-round safety
- 【Smart Monitoring & Universal Inverter Compatibility】: Stay in control with a built-in high-performance BMS and Bluetooth 5.0 connectivity, allowing real-time monitoring of voltage, current, and capacity via your smartphone app. Designed for seamless integration, it supports RS485, CANBus, and RS232 communication for RV solar setups, home energy storage, and off-grid systems—eliminating compatibility headaches and streamlining your power setup
- 【Space-saving 3U Rack Design & Hassle-free Installation】: Optimized for RVs, campers, and off-grid cabins, the compact 3U form factor (19 x 16.95 x 5.22 inches, 100 lbs) maximizes valuable setup space without compromising power. The rack-mounted design simplifies installation—no complex tools or technical expertise required—letting you quickly integrate reliable device power into tight living spaces without sacrificing storage capacity
- 【3A Active Balancing & Expandable Capacity For Growing Needs】: Avoid energy loss and uneven cell performance with 3A active balancing technology (superior to traditional passive balancing), ensuring efficient energy distribution that extends battery life and maintains optimal performance. Start with 5.12 kWh of power and scale up to 81.9 kWh by connecting up to 48 units in parallel—ideal for weekend campers, full-time RVers, or anyone needing extended off-grid runtime without replacing their entire system
- 【Multi-level Safety Protection For Peace Of Mind】: Enjoy worry-free power with an integrated smart BMS that provides comprehensive safeguards against overcharging, over-discharging, short circuits, and extreme temperatures. Combined with a durable metal casing and stable LiFePO4 chemistry, this battery minimizes risks of damage or malfunctions, ensuring reliable, safe energy storage
