Powerful 7.2V 4800mAh 21700 Rechargeable Li ion Battery Pack for Power Tools

The BAKTH-21700-2S-3 is a high-performance lithium-ion battery pack, featuring a nominal 7.2V voltage (8.4V full charge), 4800mAh large capacity, and 34.56Wh energy output. Engineered with premium 21700 cylindrical li-ion cells and a stable 2S series configuration (2 cells in series), it integrates superior energy density, consistent mid-voltage delivery, and industrial-grade durability—making it the ideal power source for portable power tools, small electric vehicles, outdoor lighting, and professional equipment that demand reliable mid-power support and extended runtime.

Crafted to solve the pain points of low-energy density batteries and unstable voltage supplies for mid-power devices:

• 4800mAh Extended Runtime with 7.2V Mid-Power: Delivers 34.56Wh of stable energy, powering mid-range devices for prolonged periods: supporting a portable electric screwdriver for 3-4 hours of continuous operation, a small electric scooter for 15-20km of travel, an outdoor LED floodlight for 25-30 hours, or a professional handheld scanner for 10-12 hours of daily use. Perfect for on-site work, outdoor activities, and daily professional scenarios where frequent recharging is inconvenient.
• 21700 High-Energy Cells & 2S Stability: Adopts advanced 21700 cylindrical li-ion cells, which boast 30% higher energy density than traditional 18650 cells. The 2S series configuration ensures precise voltage aggregation (7.2V nominal) and balanced current distribution, avoiding voltage fluctuations that may affect device performance. This combination guarantees strong and stable power output even under continuous load.

• Portable Power Tools: Electric screwdrivers, small drills, mini grinders, and handheld cutting tools.
• Small Electric Vehicles: Electric skateboards, mini scooters, kids' electric cars, and electric wheelchairs.
• Outdoor & Industrial Lighting: LED floodlights, portable work lights, and industrial emergency lighting.
• Professional Equipment: Handheld POS terminals, portable printers, and industrial sensors.
• Backup Power Systems: Mini UPS for small office equipment, security cameras, and home emergency devices.
