It fits the VP-X300, VP-X205L, SC-X220L, and SC-X205WL camcorders, along with 17 additional models in this compact camcorder range. Capacity listed here matches the original specification — 4.44Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVP-X300 and SC-X series compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell architecture, connector pinout, and BMS communication protocol.

The BMS accepted the cell on first insertion, charge termination triggered correctly at 4.2V, and the protection circuit tripped as expected under simulated over-discharge conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the VP-X300:\u003c\/strong\u003e\n    Charge this cell inside the camera body using the OEM charger on the first cycle. The VP-X300's battery management system reads the charge curve from inside the body on initial use — skipping this step can cause the remaining-battery indicator to display inaccurately for the first 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-X300 battery indicator reads full then drops without warning\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VP-X300 maps its battery-remaining display to a voltage-threshold table calibrated for the original SB-P120A's discharge curve. A new replacement cell — even one matching the spec exactly — discharges at a slightly different rate until the camera's BMS builds a usage history. During the first few cycles, the indicator can jump from high to low without passing through mid-range. This is a mapping issue, not a cell fault. After three full charge and discharge cycles, the indicator typically stabilises and tracks the actual state of charge accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVP-X300 showing \"no battery\" or rejecting a valid replacement cell on insertion\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's authentication check does not complete on first insertion — common with any new cell, including genuine replacements. The BMS expects to see a valid voltage handshake before it accepts the pack. Remove the battery, wait ten seconds, reinsert firmly, and then connect the charger without powering on the camera. Allow the charge LED to confirm an active charge state. If the camera still rejects the cell after one full charge cycle via the body, check that the gold contact tabs on the cell are fully seated against the camera's terminal block — even a 0.5mm misalignment can interrupt the circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333862490202,"sku":"BWCS-SBP120A-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333862522970,"sku":"BWCS-SBP120A-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333862555738,"sku":"BWCS-SBP120A-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBP120A-1.webp?v=1778213402","url":"https:\/\/batteryweb.com\/products\/samsung-vp-x300-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
