The Solar Capacitor Battery 4.2V 21000F Supercapacitor Pack 12V 7000 Farad is a high-performance energy storage solution designed for applications requiring rapid charge/discharge cycles and reliable power delivery. Built with a robust black plastic casing and modular cell configuration, this 12V BMS-integrated pack offers versatility for solar systems, EVs, and industrial applications.
| Feature | Specification | Application Scenario |
|---|---|---|
| Voltage Rating | 12V (4.2V/cell) | Solar energy storage, EV power backup |
| Capacitance | 21000F (7000F total*) | High-power transient load support |
| BMS Integration | Built-in 12V BMS | Overcharge/overdischarge protection |
| Material | Lithium-ion cells | Harsh environmental conditions (e.g., solar farms) |
| Certification | CE | Compliance with EU safety standards |
| Tolerance | ±20% | Flexible voltage regulation for mixed systems |
*Note: Total capacitance is derived from series/parallel cell configuration.
Adjustable capacitance and voltage configurations (via modular cell stacking) to meet specialized energy storage needs. For example, increase voltage to 24V for industrial machinery or boost capacitance for prolonged solar backup.
With a 12V BMS, you can ensure stable operation in high-power systems. Pair its 21000F capacitance with solar panels to capture intermittent energy efficiently. The compact, modular design enables easy integration into EVs or renewable energy setups.
