The Air Direct powers Canon DSLRs and mirrorless bodies — including the 5D, 6D, 7D, and R5 series — during tethered shooting sessions. Keep a charged spare in your bag so a depleted cell doesn't cut a shoot short.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCanon LP-E6 slot compatibility:\u003c\/strong\u003e\n    The Air Direct draws from a standard LP-E6 bay, sharing the same voltage rail and connector geometry as Canon's native pack. Any body that runs LP-E6 cells can accept this replacement without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Air Direct unit under a continuous data-transfer load. The BMS held voltage above the cutoff threshold and showed no false-low warnings during mid-cycle reads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    On first use, seat the cell in an OEM LP-E6 compatible charger and run one full charge before inserting it into the Air Direct. Some Canon BMS firmware requires a complete charge cycle from an external charger to calibrate the battery-remaining display accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Air Direct shows a dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCanon's BMS maps battery percentage against a discharge curve it stores from prior charge cycles. A fresh third-party cell has no cycle history in that memory, so the firmware can misread mid-range voltage as critically low. The fix is straightforward: charge the replacement fully via an OEM-compatible external charger before first use. After one or two complete charge-discharge cycles inside the Air Direct, the indicator typically stabilises and tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the connected Canon body display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a new cell's discharge curve doesn't map exactly to the reference curve stored in camera firmware, the percentage readout can skip — showing 80%, then 60%, then 75% within minutes. This is a firmware interpolation issue, not a cell fault. The cell voltage itself remains stable; only the reported figure is unreliable. Run two full charge-discharge cycles and the displayed percentage will track the actual cell state with much less variance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333731680346,"sku":"BWCS-LPE6MX-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333731713114,"sku":"BWCS-LPE6MX-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333731745882,"sku":"BWCS-LPE6MX-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LPE6MX-1.webp?v=1778213084","url":"https:\/\/batteryweb.com\/products\/tether-tools-air-direct-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
