It is integrated with smart BMS features both CANBUS and RS485 communication, ensuring perfect compatibility with over 25 leading brands of 40-60Vdc hybrid inverters worldwide.

2018

Developed the smart LV 40-60V BMS for the residential energy storage market. This system is designed to deliver intelligent monitoring, enhanced safety, and optimized performance for residential battery applications.

2017

Launched the first-generation wall-mounted battery, offering a capacity of 7 kWh to provide customers with reliable backup power and enhanced energy independence.

2016

Developed a patented 48V smart BMS for 15S and 16S, with current ratings from 200A to 400A. This system supports high-current rapid charging and discharging, engineered to replace traditional, complex BMS solutions that rely on relays. It is specifically designed for heavy-duty Automated Guided Vehicles (AGVs) and golf carts.

2015

Developed a new series of portable mobile power bank, with power ratings scaling from 500W to 3000W, to address the growing demand for flexible and off-grid power.

2014

Developed a new line of smart Battery Management Systems (BMS). Including a 4S-12Vdc model supporting 4S4P connection, as well as 8S-24Vdc and 12S-36Vdc models. These feature integrated software monitoring and Bluetooth APP, providing end-users with enhanced diagnostic capabilities and simplifying after-sales maintenance.

2013

12V LiFePO4 batteries exported to over 35 countries, delivering reliable power for trolling motors and yachts, recreational vehicles and caravans, and off-grid solar infrastructures, including LED street lighting.

2012

Led the successful export initiative for 12V LiFePO4 batteries to the United States, capturing market shares by offering a high-performance alternative to traditional lead-acid batteries. To add on, obtaining CE-EMC (safety), UN38.3 (air transport), and MSDS within the same year.

2011

Built the R&D team to design and develop the 4S-12VDC BMS (Battery Management System) and 12V (10Ah to 300Ah) LiFePO4 batteries, achieving superior cycle life within a ABS case to replace traditional gel and lead-acid batteries.
