The characteristics of high-rate polymer lithium-ion battery produced by our company: 1. High rate, currently capable of sustaining discharge 40C; 2. Low internal resistance, 40C discharge 2200mAh cell internal resistance less than 2mΩ; 3. Strong explosive force, discharge platform High, commonly used three-cell series battery is about 1V higher than the discharge platform of many similar batteries, and the initial curve of discharge does not sink; 4. The temperature is low, the battery below 2200mAh does not need to be added with heat-dissipating strips; 5. Light weight, the same 2200mAh The 3 string battery of 20C discharge, our company's battery weight is more than 20 grams lighter than the competition.
Self-Recovery Rapid Door
High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.
