Questions about this item

Should I pick the 950mAh 3.7V pack or a different capacity for my B3000E badge?

What does the 3.52Wh rating tell me about daily use in the badge?

At 3.52Wh the pack delivers roughly one full day of typical badge operation before needing a recharge.

Does the JST connector follow a standard pinout that fits the B3000N without modification?

The replacement is built to the original B3000E and B3000N specifications, so the connector mates directly with no adapter required.
