- 4-IN-1 DEVICE YOU NEED: If you’ve ever dealt with a dead car battery, you know how frustrating it can be. Whether it’s sudden power loss, expensive replacements, or batteries dying too soon, we’ve got the solution. BT521 combines a battery charger, battery tester and battery maintainer all in one, helping you keep your battery healthy, prevent unexpected breakdowns, and extend its lifespan—all while saving money on replacements
- Smart Charging: Supports both fast and standard charging to suit different needs. Delivers a stable 4.3A-5A current with low ripple and minimal heat, reducing battery wear and ensuring safe, long-term use. The 8-stage charging process precisely manages charging with phases like diagnosis, repair, constant current, constant voltage, and float charging, enhancing efficiency and effectively restoring depleted or sulfated batteries, ultimately extending battery life
- MAINTENANCE MODE: Keeps your battery in peak condition with an intelligent trickle charge that prevents overcharging, self-discharge and sulfation. This mode can extend battery life by up to 50%, reduce the frequency of replacements, and lower long-term maintenance costs. It’s ideal for vehicles in storage or seasonal use, ensuring they’re always ready to go. (Pro Tip: Charging battery once a year can significantly improve its performance and longevity)
- EASY TO USE: Install once and permanently attach to your battery, saving the hassle of repetitive installation. Access battery health data directly from your phone and enjoy real-time monitoring as long as the APP is on. In addition, with an average power consumption of only 1.5mA that it can be almost unnoticeable. So you don't have to worry about the BM300 draining your battery by being attached to it all the time (Application can monitor only one device at once)
- SEAMLESS MONITORING VIA BLUETOOTH: No more staying close to the monitor! This compact 3.2-ounce battery monitor allows you to easily track real-time battery data from inside your car or up to 33 feet away. Whether it’s rainy, sunny, or snowy, it keeps you connected with ease. Note: Bluetooth connectivity may be affected by extreme cold or obstacles. For optimal performance, use it in a clear, open area with suitable temperatures
