Wuhan Goldhome Hipot Electric Co., Ltd.
Founded in 2008 and located in the Wuhan Economic and Technological Development Zone, Wuhan Goldhome Hipot Electric Co., Ltd. is a "National High-Tech Enterprise" and a "Wuhan Municipal Science and Technology 'Little Giant' Enterprise." The company holds over 45 national patents and more than 10 software copyrights, demonstrating a strong technical foundation. In 2021, Goldhome acquired Wuhan Sangao Electric-a company with over 30 years of experience in high-voltage testing-further solidifying its technical leadership in the power testing sector.
● Outstanding Product Performance: The Goldhome HM Series Battery Internal Resistance Tester employs the AC injection measurement principle, injecting a 36 Hz AC signal into the battery and precisely calculating the ohmic resistance by measuring the AC voltage drop and current phase difference. Compared to the traditional DC discharge method, this approach allows for direct measurement while the battery is in operation, eliminating the need for discharge or shutdown, thereby significantly improving testing efficiency. The device's measurement range covers 0.1 mΩ to 100 Ω, with a voltage range of 0.000 V to 16 V (expandable to 30 V). It features an internal resistance resolution of up to 0.001 mΩ, a voltage resolution of 1 mV, and an accuracy grade of ±2.5%.
● Smart Monitoring Technology: The Goldhome tester features a built-in high-capacity memory capable of storing 3,000 sets of battery test data, with support for USB export. Equipped with a 7-inch color touchscreen, it can simultaneously display bar graphs of internal resistance and voltage for multiple cells and automatically flag abnormal batteries. Utilizing a LoRa wireless communication module, a single module can monitor 4 to 24 individual cells, with a data transmission range of up to 100 meters, making wiring safer and more convenient.
● Service Guarantees Most Important to Customers: Goldhome provides professional export packaging for international clients; all equipment is packed in wooden crates with foam padding to ensure safe ocean transport. Standard products are typically shipped within 7–15 business days, and we accept various delivery terms including FOB and CIF. Our warranty policy includes a one-year warranty and lifetime maintenance; our after-sales team commits to responding to remote support requests within one hour and providing optimal solutions within 24 hours.
