【EVE Grade A Cells】 TechCella 12V 320Ah LiFePO4 battery delivers 4096Wh energy with a 3.2kW max load. Peak discharge reaches 300A (30s). Despite its compact 14.17 x 12.2 x 6.3 in size 69.5lbs, it offers more capacity in less space—ideal for RVs, solar, and off-grid systems. Recommended charging: 14.6V, 20A–100A

【250A Smart BMS & High/Low Temp Protection】 Equipped with a 250A BMS for higher current loads, supporting powerful devices and longer runtime. It protects against overcharge, over-discharge, overcurrent, and short circuits. Auto cut-off at 0°C charging/-20°C discharging

【Smart LCD Display & Bluetooth Monitoring】 This battery features an external LCD screen that shows real-time voltage, current, and battery status—just connect it to the Monitor port using the included cable. It also supports Bluetooth monitoring via app, giving you full visibility and smarter control of your solar or off-grid system

【Multiple Interfaces & System Expansion】 Equipped with CAN and RS485 ports, the battery supports seamless communication with Victron inverters using the included CAN cable. The RS485 interface and cable allow two batteries to be connected in series to build a 24V system, offering flexible energy solutions for larger applications. Without Victron, it supports up to 4S4P (51.2V 1280Ah) expansion for large-scale off-grid power

【Durable Metal Case】 Upgraded metal shell provides superior heat dissipation, impact resistance, and fire safety—outlasting plastic cases. Side-screw design supports vertical stacking and secure mounting in tight spaces, ideal for mobile or fixed installations
