CTS 3.6V 2000mAh 3000mAh Low Temperature High discharge rate Cylindrical Li-ion

As a professional one-stop lithium battery custom solution manufacturer, CTS Battery (www.ctsbattery.com) supplies Grade A low-temperature 18650 cylindrical lithium ion cells for global agricultural machinery manufacturers, agricultural robot developers and outdoor survey equipment brands.

This 18650 cell series features a nominal voltage of 3.6V with optional capacities of 2000mAh/2600mAh/3000mAh/3200mAh. Adopting special low-temperature electrochemical formula, the cells can discharge stably from -40℃ extreme cold to +85℃ high temperature. It maintains over 60% capacity after 4-hour 0.2C discharge under -40℃, delivers stable high-rate output and outstanding cycle performance.

Perfect for harsh field and frigid outdoor working environments, these cells are widely applied in agricultural inspection robots, electric weeding farm machinery, field survey total stations, trail hunting cameras, outdoor walkie-talkies, flashlights, GPS trackers and other portable devices.

The whole series supports OEM customization with complete international certifications including CE, UN38.3, MSDS, IEC, ISO9001. Every cell undergoes full inspection of capacity, internal resistance and discharge performance before delivery. We provide stock service in EU warehouses with DDP door-to-door delivery and fast shipping within 3-5 days to meet overseas clients’ bulk order and sample demands.

• Brand New Grade A Low-Temperature Cells – 100% original brand new Grade A cells, no disassembled refurbished or second-hand cells. Each cell reaches full rated capacity with traceable QR code, excellent parameter consistency and stable low-temperature discharge performance.
• Ultra-Wide Operating Temperature Range – Works stably at -40℃ ~ +85℃ all weather conditions. No power failure for machinery in frigid winter or sun-baked farmlands, retains ≥60% capacity when discharging at -40℃, ideal for northern farm equipment and field survey devices.
• Stable High Discharge Rate – No voltage drop under high current output, stable peak discharge, perfectly match power supply demands of agricultural robot driving, high-power outdoor lights and survey instruments.
• Extra Long Cycle Life – Superior charge-discharge cycle performance for frequent repeated usage, greatly cut down total battery replacement cost of your equipment.
