The BOBOVR M3 Pro+ Dual Battery Bundle is compatible with Meta Quest 3S and Quest 3 and is designed for users who want a more complete battery head strap setup from day one. It combines the M3 Pro+ battery head strap with an extra BM60 battery and an additional charging dock, giving you one head strap, two BM60 magnetic batteries, and two charging docks in one bundle. M3 Pro+ supports two wearing styles in one strap. Use Halo Mode when you want more forehead and rear-head support for relaxed VR, movies, browsing, and longer seated sessions. Switch to Elite Mode when you want a closer and more secure fit for active games, workouts, and fast movement. The front and rear adjustment knobs let you tune the balance between comfort and stability. The dual BM60 setup is designed to reduce charging downtime. Keep one BM60 battery on the head strap while the other is charged, charging, or ready to swap. Each 18Wh BM60 battery attaches magnetically and includes a display for battery percentage and power output, so you can check battery status at a glance instead of guessing from simple indicator lights. Both charging docks can be used to manage your battery rotation more conveniently. BM60 also supports USB-C charging input at 5V/3A or 9V/2A and backup output for compatible USB-C devices at up to 5V/3A or 9V/2.22A under recommended conditions. Actual charging and play time may vary depending on headset battery level, app workload, settings, and environment. Package includes: one M3 Pro+ head strap, two BM60 magnetic batteries, two charging docks, and Type-C cables from the included products. Wall charger is not included. BM60 is a separate battery system and is not compatible with B2 or B100 battery systems.
