Suitable for Lithium Battery Monitoring This advanced 1-4S lithium battery monitor ensures precise voltage detection with ± 0.03V accuracy (far better than s ± 0.1V ). Its jumper-switching design supports all common li devices, making it a must-have tool for your electric, or power bank projects. The one-touch LED indicator clearly shows remaining capacity at 100%, 75%, 50%, and 25%, giving you peace of mind when managing your lithium batteries.; Zero Static Power Consumption Unlike traditional monitors that drain your battery, this innovative device consumes ZERO static power (0A), ensuring no energy loss during use.
Whether you're working on a small-scale project or a large-scale system, this feature guarantees maximum efficiency and longevity. Plus, its adaptive response time (2-6 s nds) adapts to your batterys voltage level, providing timely alerts when needed most.; Built for Durability & Safety Designed with safety as a top priority, this battery monitor features a robust anti-reverse connection warning and a glass fiber PCB board to prevent accidental damage. It also includes a non-waterproof design, so avoid exposing it to rainwaterthough applying triple-proof paint can enhance durability further. Rest assured, this monitor is built to last under conditions.
; Crystal-Clear Voltage Indication With its intuitive four-segment LED display, this monitor provides crystal-clear visibility of your battery's status. For example, testing a fully charged 4S battery pack ( 16.8V ) showed a nominal threshold of 15.2V with only a + 0.01V errora testament to its precision. Even in low-voltage scenarios, such as a single-cell 3.21V test, the monitor triggers a visible low-voltage flash within 2.1 s nds, preventing over-discharge issues.; Versatile Compatibility Compatible with 1-4S lithium batteries, this monitor offers adaptability across various applications. Whether youre managing a s power system, optimizing an electric scooters performance, or upgrading your home solar storage setup, this monitor fits Suitablely into your workflow.
