Lithium battery charge and discharge balance repair device through charge and discharge management and balance repair, extend battery life, improve performance, enhance safety, and has the advantages of easy operation, wide application, environmental protection and energy saving, is an ideal tool for lithium battery maintenance.

Heltec Energy cutting-edge equalizer is designed to provide comprehensive, efficient balancing of your battery system, ensuring optimal performance and longevity. The  Battery Equalizer is engineered to ensure that each individual cell within a lithium battery pack operates at its maximum potential. By equalizing the voltage and current across all cells, this device effectively balances the energy distribution, preventing overcharging or undercharging of any specific cell. This not only enhances the overall efficiency of the battery pack but also extends its lifespan, ultimately saving you time and money on replacements.

Heltec VRLA/lithium battery charge and discharge test machine –designed to meet the needs of electric vehicle dealers and battery manufacturers, this purpose-built battery capacity tester provides precise capacity discharge detection and comprehensive functionality for series charging.

Heltec Energy battery spot welding machine is equipped with advanced technology that eliminates interference with AC power and prevents switch tripping, ensuring a seamless and efficient welding process. This machine adopts high-energy polymerization pulse welding capability, with concentrated and small welding spots and deep molten pool penetration, preventing the welding spots from turning black and ensuring high-quality and durable welds. In addition, the dual-mode spot welding trigger enables precise, fast and efficient welding, making it easy to weld different parts.

Heltec new spot welding models are more powerful with max peak pulse power of 42KW. You can select the peak current from 6000A to 7000A. Specially designed for welding copper, aluminum and nickel conversion sheet, SW02 series support thicker copper, pure nickel, nickel-aluminum and other metals welded easily and firmly (support nickel plated copper sheet and pure nickel direct welding to the battery copper electrodes, pure copper sheet direct welding to the battery copper electrodes with flux). HT-SW02H is also capable of resistance measurement. It can measure the resistance between the connecting piece and the electrode of the battery after spot welding.

Unlike inductive balancers, capacitive balancers can achieve group balancing. It does not require a voltage difference between adjacent batteries to start balancing. After device activation, each battery voltage will reduce the capacity decay caused by the battery bucket effect, thereby shortening the duration of the problem.

As the number of battery cycles increases, the degradation rate of battery capacity becomes inconsistent, leading to severe voltage imbalance in the battery. The ‘battery bucket effect’ can affect battery life. That’s why your battery pack needs an active balancer.

The Heltec Energy HT-LS02G battery gantry laser welding machine adopts a fully automatic gantry structure. Flexible welding of various types and sizes of lithium battery modules. Precision welding reduces the contact resistance of lithium batteries during assembly, improving the output and performance of lithium battery modules. Automated production has high efficiency and a simple operating system. The output power is 1500W/2000W/3000W, which is convenient for welding vehicle batteries and can mark the nameplate of the lithium battery module housing.

The instrument adopts high-performance single crystal microcomputer chips imported from ST Microelectronics, combined with high-resolution A/D conversion chips from Microchip in the United States as the measurement and control core, and uses a precise 1.000KHZ AC positive current synthesized by a phase-locked loop as the measurement signal source applied to the measured component. The weak voltage drop signal generated is processed by a high-precision operational amplifier, and the corresponding internal resistance is analyzed by an intelligent digital filter. This instrument has the advantages of high accuracy, automatic file selection, automatic polarity discrimination, fast measurement speed, and wide measurement range.

The handheld laser welding machine for lithium-ion batteries supports the welding of copper/aluminum from 0.3 mm to 2.5 mm. It can be used for welding lithium iron phosphate battery poles, cylindrical batteries, aluminum and lithium iron phosphate batteries, copper and copper electrodes, etc., with high precision, portability, high efficiency, wide range of applicable materials, non-contact welding, high degree of automation, environmental protection and safety and low cost advantages, widely used in precision manufacturing, electronics, automotive and other industries.
