【New Version Upgrades – WiFi Monitoring & Fire Suppression】 Upgraded with WiFi remote monitoring in addition to Bluetooth app control, allowing you to check battery status anytime and anywhere once WiFi is configured. Built-in fire suppression and anti-explosion protection activates within milliseconds when temperature exceeds 170°C (338°F)—helping suppress thermal runaway and extinguish flames before risks escalate

【Optimized Terminal Layout – Left Positive / Right Negative】 The upgraded terminal layout features left-positive and right-negative positioning, improving wiring clarity, reducing installation errors, and enhancing overall system safety—especially for rack-mounted and parallel 48V battery systems

【Multi-brand Inverter Communication】 Techex 48V 100Ah LiFePO4 rack mount battery supports smooth communication with popular inverter brands like Victron, Pylontech, Luxpower, Sol-Ark, DEYE, GoodWe, and more. Equipped with CAN and RS485 communication ports, it includes a communication cable for easy integration—ideal for off-grid solar, home energy storage systems, and telecom backup

【Upgraded 100A BMS with Grade-A EV Cells】 Built with 16 Grade-A EV LiFePO4 cells and an upgraded smart BMS, this server rack 48V lithium battery delivers outstanding cell consistency, ultra-low self-discharge, and over 6000 deep cycles. Charging from 0°C/32°F - 55°C/131°F and discharging from -20°C/-4°F - 60°C/140°F—ensures safe and reliable operation in both hot and cold environments

【Dual Switch, Dual Terminals & Fast Plug】The switch activates the BMS for a secure system startup, while the built-in 125A breaker controls terminal output and cuts off power during overcurrent—protecting your deep cycle 48V battery. Dual terminals ensure balanced current, lower heat, and prevent overload. Equipped with fast plug connectors for quick, tool-free installation—safe, anti-reverse, and highly conductive

【3U Rack-Mount Design, Supports Up to 15P】Designed for scalable energy storage, this 3U 48V LFP rack-mount battery (17.40" x 18.89" x 5.23", 100 lb) features a durable metal case and solid handles for easy installation. It supports up to 15 units in parallel—ideal for home backup, workshop, or off-grid solar battery systems.
