Four-battery pack for GoPro HERO 9, 10 and 11

This set contains four lithium-ion cells built to replace the original GoPro ADDBD-211, ADBAT-001 and ADDBD-001 batteries. Each unit delivers 7.3 Wh at 3.85 V with a 1900 mAh rating. The pack suits owners of HERO 9 Black, HERO 10 Black and HERO 11 Black cameras who want spare power for long shooting days.

UL1642 and CE certified cells

Every battery meets UL1642 and CE safety standards and includes built-in guards against over-charge, over-discharge, over-voltage, over-current and over-heating. The cells slot directly into the camera battery compartment and work with the standard GoPro charger, so no extra cables or adapters are required for daily use.

Replaces single OEM batteries for extended sessions

Swapping a single factory cell for this four-pack lets you cycle through fresh power without stopping to recharge. The upgrade is worthwhile when you record back-to-back activities such as sports, travel or events where mains charging is impractical. It does not help users who need higher-capacity cells than 1900 mAh or who shoot with cameras outside the HERO 9, 10 and 11 Black range.

Questions about this item

What voltage does the Kastar BA-4B-GOPRO11 battery deliver and how does that affect run-time?

Each cell is rated at 3.85 V and 1900 mAh, giving 7.3 Wh of energy for longer shooting sessions.

Will the four-pack fit inside the battery compartment of a HERO11 Black without modification?

Yes, the batteries are direct replacements for the GoPro ADDBD-211 and ADDBD-001 cells used in HERO9, HERO10 and HERO11 Black models.

How do I install the batteries correctly and what common mistake should I avoid?

Open the camera's battery door, insert each cell with the contacts facing inward, and close the latch fully; the frequent error is leaving the door unlatched, which cuts power.
