## Features

- 【Portable】Internal resistance is an important indicator of battery performance. This handheld battery internal resistance tester can measure the internal resistance and voltage at the same time, adopting the Kelvin four-wire test clip, which better avoids the influence of contact resistance and wire resistance, and is able to carry out more accurate measurements.
- 【Good Tool to Test Battery Performance】This internal resistance tester can help you figure out good and bad batteries. To process series-connected battery packs, it is necessary to match the capacity, internal resistance and voltage of the cells. It is suitable for testing lead acid, lithium ion, lithium iron phosphate etc. Good tool to test battery performance before you DIY battery packs.
- 【PC Connection】You can connect this device to computer to analyse the data more conveniently. This voltage and internal resistance tester adopts intelligent control, LCD display, and implanted Kalman filter mathematical algorithm, which has the advantages of high precision, high efficiency, low cost, light weight, energy saving.
- 【Wide Application】This battery voltage test meter is widely used in various battery production, cell phone, computer, electric vehicle and other battery maintenance, testing, scientific research laboratories and other occasions. It can also be used to measure the AC resistance of capacitors and low resistance value high precision resistance.
- 【What You Get】1* internal resistance tester, 1 pair of probe, 1* user manual. We provide one year after sale service and lifetime technical support. Please feel free to contact us if you have any concerns.
