Both models run the same 7.4V cell stack with a shared connector footprint and BMS protocol. When the stock battery no longer holds a useful charge, this is the direct cell replacement to restore the lamp to full output.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEVO3 and Lichtfabrik LED platform:\u003c\/strong\u003e\n    Both lamps share the same battery bay dimensions and 7.4V nominal rail. The BMS handshake on each uses the same thermistor pin, so the protection circuit communicates charge state identically across both models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on a controlled load bench at the lamp's rated draw. The BMS held its overcurrent threshold through repeated high-brightness mode switching without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHigh-brightness mode thermal load:\u003c\/strong\u003e\n    Running the EVO3 at full LED output in an enclosed space generates more heat in the battery bay than intermittent use does. Allow the lamp to cool for five minutes after sustained full-brightness sessions before recharging — this keeps cell temperature within the BMS charge-acceptance window.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the EVO3 dims suddenly at high-brightness mode without warning\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EVO3's BMS monitors cell voltage under load. When an aging or deeply discharged cell drops below roughly 3.0V per cell (6.0V total at the pack terminals), the protection circuit throttles output before a hard cutoff. This shows up as sudden dimming rather than an abrupt shutdown. A fresh 2200mAh pack recovers this headroom and keeps the BMS away from the low-voltage threshold during full-output use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger LED stays red and never transitions to green on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the pack has sat in storage long enough for cell voltage to fall below the charger's acceptance threshold — typically under 5.5V on a 7.4V pack. The charger reads the low voltage as a fault condition and refuses to enter CC mode. Some AS-Schwabe chargers support a recovery or \"boost\" trickle phase; leave the pack connected for 15–20 minutes and the charger will often re-check the pack voltage and transition. If the LED stays red past 30 minutes, measure pack terminal voltage — anything above 5.0V means the charger should eventually accept it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416071110746,"sku":"BWCS-BST200PW-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416071143514,"sku":"BWCS-BST200PW-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416071176282,"sku":"BWCS-BST200PW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST200PW-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/as-schwabe-handlampe-evo3-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
