This minimizes the risk of switching off the buffer unintentionally. Likewise, some time passes before switching off, so that in the event of an accident, the switch can be quickly switched back to Pos on.\u003cbr\u003e\nOverview:32 bit, 48MHz MCU control of the buffer unitAdaptive chargingcurrent sensorExternal alarm output *With RC switch-offApplication:Backup battery for electric helicopters for safe emergency landingCurrent peak buffers for remote-controlled models (airplane, helicopters, etc.)Effective buffering of servo return currentsFully automatic setup **Maximum ratings:Maximum voltage (INPUT) 10VMaximum buffer voltage (OUTPUT fully charged) 8.5VShort-term peak current 25 ampsTechnical specifications:Width: 17 mmLength: 49 mmHeight 29 mmWeight: approx. 27 gCAPs: 3 x 25 FCable length: 18 cmPlug: Graupner \/ JR UNIInput voltage: 5.6 V to 10 V* optionally available in a later software version** The switch-off voltage is currently NOT adjusted automatically and is preset to 3.4 volts\u003cbr\u003e\nAttributeswill fit inSG520 | SG521 | SG522 |ModuleBEC BackupPart number1st9540.01\u003c\/p\u003e","brand":"Hubtech-RC","offers":[{"title":"Default Title","offer_id":58105544474998,"sku":"1st9540.01","price":49.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/2547\/6214\/files\/04-1st9540-01-standard.jpg?v=1781701534","url":"https:\/\/7tn0ci-jr.myshopify.com\/products\/1st-buffer-pack-25f-v4-81-for-helis-450-700-1st9540-01","provider":"Hubtech-RC","version":"1.0","type":"link"}
