It fits the VP-DX100i, VP-D381, VP-DX105i, and SC-D385 compact camcorders. The cell matches the original voltage rail and connector footprint for those models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVP-DX100i and VP-D381 series compatibility:\u003c\/strong\u003e\n    These models share the same battery bay geometry, 7.4V nominal rail, and IA-BP80W connector pinout. The BMS handshake on each body reads the same cell identification — one battery covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a VP-DX100i body. The BMS accepted the cell without error, reported charge status through the indicator, and held voltage above 6.8V through the working discharge range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the VP-DX100i:\u003c\/strong\u003e\n    Run the first full charge inside the camera body or the OEM Samsung charger rather than a generic third-party charger. The VP-DX100i BMS maps battery-remaining percentage against the cell's discharge curve during that initial cycle — skipping it can cause the indicator to read erratically for several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VP-DX100i shows a dead-battery icon on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's camcorder BMS uses a stored voltage-threshold map to calculate remaining charge. A new cell that hasn't completed a calibration cycle presents a discharge curve the BMS hasn't seen before, so it defaults to low or empty. This isn't a faulty cell — it's a mapping mismatch. Charge the battery to full inside the camera body or OEM charger, then run it down through normal recording use. After one complete cycle, the indicator tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during playback or recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VP-DX100i samples cell voltage at brief intervals and maps those readings to percentage steps. A replacement cell with a slightly different discharge curve produces voltage readings that land between the original threshold steps, causing the display to skip or jump. This is most visible in the middle charge range — roughly 40% to 70%. One full charge-discharge cycle inside the camera body re-anchors the threshold map to the new cell. After calibration, the percentage display stabilises and steps down in a consistent pattern.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333873041498,"sku":"BWCS-BP80SW-1","price":24.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333873074266,"sku":"BWCS-BP80SW-2","price":28.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333873107034,"sku":"BWCS-BP80SW-3","price":30.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP80SW-1.webp?v=1778213290","url":"https:\/\/batteryweb.com\/products\/samsung-vp-dx100i-replacement-battery-74v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
