Structure: Single cell with low-temperature formula integrated inside metal housing, fitted with two 12*33mm metal terminal posts for positive and negative poles, adopting an integrated hermetically sealed shell structure.
Specifications:Operating voltage: 2.5V~4.2V,Nominal capacitance: 45000F / 21Ah (tolerance: -20%~+50%),AC internal resistance ≤0.4mΩ (1kHz / 20℃), DC internal resistance ≤0.83mΩ
Standard charge-discharge current: 105A (5C); Max continuous charge-discharge current: 315A (15C); 30s peak current: 400A,Max stored energy: 71.18Wh,Self-discharge ≤5% after 3 months storage at 25℃,Operating temperature: -40℃~60℃; Storage temperature: -40℃~70℃; Recommended storage voltage: 3.35V±2%,Dimensions: 159.4×88×62mm, weight approx. 1.24kg,Standard cycle life at 25℃ ≥10,000 cycles
Advantages: Supports ultra-high rate charge and discharge, continuous high current output at 15C and short-time peak current up to 400A. Ultra-wide temperature performance enables stable 4C discharge even at -40℃ with controllable capacity attenuation under high and low temperatures. The metal housing delivers excellent sealing performance with zero leakage and no thermal runaway risk. Low self-discharge rate ensures minor performance degradation during long-term storage. Standard terminal posts allow flexible series and parallel assembly for high-voltage energy storage modules, widely applicable to mining truck power systems, oilfield energy recovery, grid frequency regulation, backup power for AI data centers, low-speed EV energy storage and other scenarios.
