  • BATTERY COMPATIBILITY: Compatible with ① Lithium battery packs ranging from 3 to 20 cells, ② LiFePO4 battery packs ranging from 4 to 24 cells, and ③ Lead-acid batteries available in 12V, 24V, 36V, 48V, 60V, 72V, and 84V. Additionally, this product supports other types of battery from 7V to 100V.
  • DISPLAY FEATURE: This item is furnished with a digital LCD display that includes a brighter backlight which can display well even under intense sunlight. It is protected by a reinforced Acrylic screen designed to be water-resistant, allowing it to show both the battery voltage and the remaining capacity at the same time. This feature ensures that users can easily and clearly monitor the battery status.
  • Custom Mode: Also known as the Professional Mode. It uses a 5-point measurement method, where the chip employs a new algorithm to calculate the voltage values at 5 custom SoC points, deriving the SoC-voltage curve. This method reduces SoC errors by 20-50% compared to general modes, allowing customers to apply this product in commercial-grade projects.
  • Power-off Memory Feature - The battery tester has a power-off memory function, which means that after the power supply to the voltage meter is cut off, the functional settings remain as they were before the power was lost.
  • Energy-Efficient Design - The voltage tester features minimal power consumption; in standard mode, it draws less than 15mA, and in low-power mode, the current is reduced to below 1mA.
  • Audible Low Voltage Alert - The device has a built-in buzzer that alerts you with a sound and a flashing battery icon when the battery voltage falls below your set warning level.
  • Waterproof Rating - IP67 waterproof, fully enclosed casing, outdoor and humid environments will not affect the product's functionality.
  • Easy Installation - The wire length is approximately 11.8 inches (30 cm), and we provide double-sided adhesive tape for easier installation.

  • 【Working Principle】: The welding process is based on the principle of high current and high temperature, fast melting part of the nickel sheet, and cooling, which can fully meet the requirements of a small spots welding machine, stable quality, solid welding, and no tube frying.
  • 【Display OLED 】: More intelligent, accurate, and humane to use, the adjustable digital display clearly shows battery voltage, current size, welding pulse, interval, and number of spotwelds at a glance.
  • 【Adjustable Welding Strength】: With a high power output design, the encoder flexibly adjusts the welding strength, easy to find a more suitable gear for different materials, the welding process is more accurate and the welding effect is more complete. Suitable for continuous welding of thousands of points on nickel sheets and nickel-plated sheets.
  • 【Scientific Circuit Design】: Adopting 5pcs high-power MOS, MOS boost circuit drive, ensuring MOS stability, with large current control, with big ridundancy and low failure rate. Paired with 2 large filter capacitors, stable-performance anti-interference MCU, and paired with 8AWG silicone welding wire. With its portable features, go out of the maintenance of cellphones is more convenient.
  • 【Support Input Type】: supporta la tensione da 7 V a 14 V, corrente di più di 200 A. Suggested power input of 12.0 V 20 A auto starters, 3 series -6 series supercapacitors, and 3S 5000 mAh or above aviation model batteries.
