We specialize in the R&D and mass production of 72V low-loss lithium batteries, tailor-made for high-voltage scenarios such as high-speed electric vehicles, site operation equipment, heavy-duty mobility tools and commercial transportation equipment. Serving as an upgraded replacement for traditional 72V lead-acid batteries and ordinary high-voltage lithium batteries, all products strictly comply with IEC 62133-2 international safety standards and EU RoHS environmental directives. Focusing on full-dimensional low-loss performance, our batteries optimize static power loss, dynamic working condition loss, long-term service life loss and operation and maintenance loss. They effectively solve common industry pain points of traditional high-voltage batteries, including high self-discharge rate, large load voltage drop, severe power attenuation, rapid aging and high maintenance loss. Greatly improving the power utilization rate and long-term operational stability of equipment, our low-loss batteries serve as the optimal high-voltage power solution for commercial heavy-duty, high-frequency and long-term operating equipment, meeting the bulk supporting and upgrade demands of various 72V high-voltage electric equipment worldwide.

　　In terms of static power loss control, our 72V lithium battery features extremely low self-discharge, thoroughly improving the problems of power depletion and virtual power loss of traditional batteries. Traditional 72V lead-acid batteries and low-quality lithium batteries suffer from high self-loss during long-term storage, resulting in significant power drop and voltage decline after idle placement. This not only causes power waste, but also easily triggers cell sulfation and premature capacity attenuation, leading to early battery scrappage. Adopting high-purity stable lithium cells and precise cell sorting technology, our 72V low-loss lithium battery features highly consistent single-cell parameters and ultra-low internal resistance. The monthly self-discharge rate at room temperature is controlled at an extremely low level, with no obvious power loss during long-term static storage. No frequent supplementary charging is required, effectively eliminating invalid power loss, reducing energy consumption caused by repeated charging, and minimizing equipment standby loss.

　　The battery delivers excellent dynamic low-loss performance, solving power attenuation problems under heavy-load, high-speed and climbing conditions. Traditional 72V high-voltage batteries are prone to severe voltage drop and obvious power attenuation during start-up acceleration, heavy-load driving and continuous climbing, causing weak acceleration, reduced speed and shortened endurance with serious operating power loss. Featuring a stable discharge platform and low internal resistance cell design, our product supports high-current discharge with minimal voltage fluctuation under full-load, high-speed and frequent start-stop conditions. It maintains stable voltage output and constant power, minimizing operating power loss, converting rated capacity into effective endurance and operating power to the greatest extent, and eliminating virtual capacity and unavailable power loss to achieve longer endurance and higher operating efficiency than ordinary batteries with the same capacity.

　　It greatly reduces long-term life loss with superior anti-aging and anti-attenuation capabilities that far exceed traditional batteries, slowing down performance degradation. After short-term cycling, ordinary high-voltage batteries suffer from sharp internal resistance increase, cell imbalance and rapid capacity drop, resulting in fast life loss and frequent replacement with high iterative costs. Equipped with a customized high-voltage dedicated intelligent BMS, our 72V lithium battery monitors the voltage, current and temperature of each cell in real time and dynamically balances cell voltage differences. It effectively avoids core aging risks caused by overcharge, overdischarge, overload and high temperature, restraining capacity attenuation and performance loss from the source. With a far longer cycle life than traditional lead-acid batteries, it maintains a high capacity retention rate after thousands of charge-discharge cycles, delivering stable performance and uniform attenuation without sudden failure. It greatly extends the service life of the battery and reduces equipment downtime loss, procurement loss and maintenance loss caused by frequent battery replacement.

　　Optimized in operation and environmental loss, the battery realizes full-cycle low-loss operation. Traditional 72V lead-acid batteries require regular water replenishment, voltage detection and balance maintenance, bringing cumbersome procedures and high labor and time loss, and battery aging will be accelerated without proper maintenance. Adopting a fully sealed maintenance-free design, our product eliminates daily maintenance and thorough operation loss. Meanwhile, the high-strength sealed structure provides waterproof, dustproof, shockproof and wide temperature resistance, operating stably from -20℃ to 60℃. It resists performance loss and failure loss caused by high-temperature thermal attenuation, low-temperature power deficit, vibration, humidity and dust, optimizing environmental adaptability and reducing external interference loss. Fully certified with IEC safety and RoHS environmental compliance, the battery is green and pollution-free with no harmful substance precipitation or acid leakage, ensuring zero compliance loss and trade risks for global market application.

　　Supported by large-scale mass production and refined quality control systems, every 72V lithium battery undergoes strict pre-delivery tests including self-discharge detection, full-load loss test, high and low temperature durability test and cycle attenuation test, ensuring unified loss parameters and stable performance for each batch. We provide customized capacity, size, terminal and wiring harness solutions for loss-free replacement of various 72V original batteries with plug-and-play convenience. With the core advantages of full-dimensional low loss, long service life, maintenance-free operation and high stability, our products effectively reduce customers’ power loss, equipment loss, maintenance loss and iterative loss, improving equipment operating efficiency and long-term cost performance in an all-round way and providing efficient, energy-saving and reliable power upgrade solutions for global high-voltage electric equipment users.
