The 7000mAh capacity (2x3500mAh in parallel) provides extended runtime, ideal for applications requiring long operational periods without frequent recharging, such as drones, portable medical devices, or camping gear.
The 2s2p configuration combines 7.4V (2 cells in series) with doubled capacity (2 cells in parallel). This balances voltage needs for mid-power devices while supporting higher current demands safely.
NCR18650GA cells are known for stable lithium-ion chemistry with built-in safeguards against overcharge/over-discharge. A Battery Management System (BMS) often included in such packs ensures cell balancing, overcurrent protection, and thermal management.
NCR18650GA cells typically endure 500+ charge cycles with minimal capacity loss, making the pack cost-effective over time compared to shorter-lived alternatives like LiPo batteries.
The GA cells offer excellent energy density, resulting in a compact, lightweight pack suitable for space-constrained applications (e.g., handheld tools, portable lighting).
Built with widely available 18650 cells, the pack is easy to repair or reconfigure. The 2s2p setup can be expanded for diverse projects.
Parallel configuration doubles the discharge capability. While NCR18650GA cells have a moderate 10A max discharge each, the 2p setup allows up to 20A continuous, suitable for medium-power devices like electric scooters.
NCR cells exhibit better thermal performance under load compared to high-drain cells, reducing overheating risks in prolonged use.
Combines premium cell quality with a modular design, offering durability and adaptability at a competitive price point for mid-range applications.
Portable electronics, power tools, LED lighting systems, small electric vehicles, and backup power solutions where a balance of voltage, capacity, and safety is critical.
