FAQ for Professional Power Tool Batteries
A: We use a combination of ultra-high-discharge-rate (High-C) cells, often in a multi-cell series/parallel configuration (e.g., 5S2P for a 10-cell pack). The BMS is also built with high-power MOSFETs and thick internal connections to handle the high amperage.
A: We design our packs for extreme durability. This includes using impact-resistant polymers for the housing, internal cell holders for shock absorption, and strong ultrasonic welding. We can design and test to meet specific drop requirements, such as 3 meters onto concrete.
A: Due to the custom engineering, housing molds, and certifications, our MOQ for a new power tool battery typically starts at 50,000 to 100,000 units.
A: Yes, creating a unified battery platform is a core service. We can design a single battery form factor with a communication protocol that works seamlessly across all tools in your product line.
A: Our professional tool batteries are designed for a long and demanding service life, typically specified to retain high capacity after 500-1000+ charge cycles, depending on the cell chemistry selected.
A: Given the complexity of the custom housing and high-power BMS, the lead time for the first batch of functional prototypes is typically 8-10 weeks.
A: We use cells with very low internal resistance (IR) to minimize heat generation. The BMS includes multiple temperature sensors for active thermal monitoring and protection, and the pack housing is designed to facilitate airflow and heat dissipation.
A: Absolutely. We can create a family of battery packs with different capacities that share the same physical interface, allowing users to choose between a lightweight/compact option and a high-capacity/extended runtime option.
A: Yes. We manage the entire certification process to ensure your battery pack meets all required standards for your target markets, including CE, UL 2054, IEC 62133, and UN38.3.
A: Please provide your tool’s voltage (e.g., 18V), required capacity (Ah), the continuous and peak current draw (Amps) of the most demanding tool in your lineup, dimensional constraints for the pack, and your estimated annual volume.
