Basic Product Overview
This Mutian 21V rechargeable lithium battery pack features standardized and complete product specifications, with a unique independent model number and foreign trade code, making it perfectly suitable for global retail, bulk wholesale, and cross-border export sales across all channels. The product is manufactured in Fuzhou High-tech Industrial Park, Jiangxi Province, China. Leveraging the factory’s standardized quality control system and large-scale production capacity, the shipment is stable, quality control is strict, and full traceability is possible. The battery casing is made of thickened high-strength ABS engineering plastic molded integrally. It undergoes precise anti-slip, wear-resistant, scratch-resistant, and impact-resistant surface treatment, enabling it to withstand complex conditions such as outdoor construction sites, high-temperature workshops, and open-air construction, effectively resisting bumps, falls, and dust erosion. It is unlikely to deform, crack, or break over long-term use. The cell uses Mutian’s dedicated multi-series structure, available in two high-rate specifications: 1,300 mAh (3C) and 2,000 mAh (5C), continuing Mutian LXT battery’s core advantage of high energy density. It is smaller in size, lighter in weight, and offers greater energy storage. The product’s standard nominal voltage is 18.5V, full charge voltage is 21.0V, and discharge cut-off voltage is tightly controlled between 13.75V and 15.0V. The internal resistance of the battery is ≤60 mΩ, with no false labeling and zero voltage drop, ensuring continuous and balanced voltage output. Optimized cell layout and temperature control structure completely eliminate issues such as local overheating, sudden power loss, and rapid cell degradation, significantly improving the overall durability and cycle stability of the device. The lightweight ergonomic body design combines structural strength with 1.2-meter free fall protection capabilities, allowing long-term handling during construction without heavy load stress, making it suitable for prolonged high-frequency operations.
Performance parameters and protection features
The Makita 21V lithium battery pack features a full-gradient capacity specification, offering eight versions: 1.3Ah, 2.6Ah, 3.9Ah, 5.2Ah, 2Ah, 4Ah, 6Ah, and 8Ah. It meets the needs of all scenarios, including home light-duty DIY use, commercial professional installation, and industrial heavy-duty operations. It supports both 3C and 5C high-capacity discharge modes; the standard discharge current ranges from 0.5C to 1C, while the peak discharge current is strong and stable, enabling instant delivery of high power. It is suitable for high-power Makita tools such as angle grinders, electric saws, and impact wrenches. Complemented by a constant-current and constant-voltage intelligent charging system, it charges smoothly without damaging the cells, offers high efficiency and conversion rates, effectively slows down cell degradation, and significantly extends the overall battery lifespan. The product is compatible with a wide temperature range: charging operates from 0°C to 45°C, discharging works from -20°C to 60°C, and safe storage from -10°C to 30°C. It can handle various extreme working conditions, such as severe cold outdoor environments, high-temperature construction sites, and enclosed workshops. It includes an upgraded intelligent BMS battery management protection board with six intelligent protections: overheat, overvoltage, overcurrent, short circuit, overload, and PTC. It monitors cell temperature, voltage, and current in real time, eliminating potential safety risks such as cell swelling, overheating, short circuits, and deep discharge. The device features four-stage high-definition LED battery indicator lights that display remaining power levels visually, allowing accurate prediction of runtime and preventing power outages during work. It uses Makita’s original clip-type terminal interface, ensuring smooth plugging, tight contact, and vibration resistance without loosening, thus avoiding contact failures that could cause power outages. The air inlet has a dust-resistant design with a detachable precision filter, enabling regular cleaning of dust, wood chips, and debris, preventing heat dissipation blockages and ensuring long-term stable cooling. The body lacks digital displays or foldable handles; it is solidly molded for durability, making it suitable for overseas industrial-grade high-frequency, high-stress long-term operations.

Instructions for Using the Product
The newly manufactured Matake-compatible lithium battery comes pre-charged with a baseline charge level. To fully activate the A+ grade cell performance, optimize discharge characteristics, and extend overall cycle life, it is recommended to fully charge the battery before first use and then begin operational tasks. When stored idle for an extended period, the battery should undergo a complete charge and discharge cycle every two months to effectively prevent cell undercharge dormancy, capacity degradation, and increased internal resistance. It should be kept in a dry, cool, and well-ventilated clean environment, away from high temperatures, direct sunlight, moisture, water accumulation, and flammable or explosive areas. Charging must use the dedicated 21V original charger provided with this product; mixing with chargers of other specifications or brands is strictly prohibited to avoid unstable current, abnormal voltage, short circuits, overheating, or cell damage. Charging should be conducted in an open, dry, well-ventilated area free of debris and flammable materials. Once fully charged, disconnect and remove the charger promptly to avoid prolonged overcharging or floating charging that may damage the cells. Direct shorting of the positive and negative terminals with metal objects is strictly forbidden, as is soaking in water, violent impact, squeezing, burning with an open flame, or high-temperature baking. The battery features a sophisticated intelligent protection system; non-professional personnel should not disassemble, modify, weld, or repair it without authorization. If abnormal symptoms such as excessive heat generation, swelling, power loss, poor contact, or rapid power degradation occur during use, immediately stop using the battery, allow it to cool in a well-ventilated area, and contact customer service for assistance—do not attempt repairs yourself. Used batteries must be classified and recycled in accordance with international environmental standards to prevent random disposal and avoid environmental pollution and safety hazards.
