OM\u2019s box list matches that.<\/p><\/div>\n  <div class=\"faq-item\"><h3>What 410 CIPA shots means for a day<\/h3><p>CIPA 410 is the stills number OM published. Fstoppers\u2019 readout of the same brief also lists about 80 minutes of video under CIPA, or about 130 minutes when zoom and extra operations stay off. A spare BLS-7 is the stills-day hedge; USB-C is the overnight hedge.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Why BCS-7 costs more than the battery<\/h3><p>BCS-7 is $119.99 and ships without an AC adapter. The 90-minute figure needs F-7AC and CB-USB13. The charger\u2019s job is to free the camera. The cell\u2019s job is a second 410-shot tank. They are different purchases.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Whether IPX1 applies on the charger<\/h3><p>OM\u2019s splash footnote: sealing applies when the PEN is paired with a dust- and splash-proof lens, and it does not apply during charging or HDMI connection. Park the camera to charge.<\/p><\/div>\n<\/div>\n\n<h2>Final Verdict<\/h2>\n<div class=\"conclusion-module verdict-box\">\n  <div class=\"verdict-picks\">\n  <div class=\"verdict-item\">\n  <span class=\"verdict-label\">\ud83c\udfc6 Best Overall:<\/span>\n  <div class=\"verdict-product\"><strong>OM SYSTEM BLS-7<\/strong> <span class=\"verdict-reason\">\u2013 The specified 1285 mAh cell.

Take the BCS-7 when a second cell should charge while the body stays packed. Take the F-5AC when the only gap is the missing wall adapter. Leave BLS-50 on the E-P7 and BLX-1 on the OM-1. This camera is a BLS-7 body.<\/p>\n<\/div>\n<p><strong>Worth knowing before you order.<\/strong> Third-party battery kits are one of the categories that reliably discount during <a href=\"https:\/\/www.cameraegg.org\/camerareview\/amazon-prime-big-deal-days-2026-camera-gear\/\">Prime Big Deal Days on October 6\u20137<\/a>; first-party packs usually do not.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The OM SYSTEM PEN ships with one new BLS-7 and no charger.
