It fits model 03.5451 and is a direct swap for OEM part 03.5343. The VEGA 1500 C+R is a rechargeable inspection flashlight used in automotive bays, workshops, and low-light maintenance environments.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVEGA 1500 C+R platform fit:\u003c\/strong\u003e\n    The VEGA 1500 C+R uses a three-cell 11.1V Li-ion pack with a specific BMS handshake that governs both charging via USB-C and output regulation across lumen modes. This pack matches the voltage rail and connector pinout that the driver circuit expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the VEGA 1500 C+R driver board across all output modes. The BMS held stable cutoff thresholds on both charge input and high-draw discharge, with no spurious low-voltage trips during turbo output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMulti-cell replacement rule:\u003c\/strong\u003e\n    The VEGA 1500 C+R draws hard in turbo mode. Mixing a new pack with partially degraded cells from another unit accelerates imbalance — the weaker cells deplete first and get driven below safe voltage under load. Always replace the full pack in one go, not cell by cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VEGA 1500 C+R steps down output before the indicator shows low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VEGA 1500 C+R's driver circuit monitors cell voltage continuously, not just average pack voltage. When any cell drops toward 3.2V under load, the driver steps down lumen output to protect the cells — even if the LED indicator still shows a charge remaining. This is intentional brownout protection built into the driver, not a fault. If the light dims noticeably in turbo before the indicator blinks, the pack is at the edge of its usable range. Switching to a lower output mode at that point draws less current and keeps voltage above the cutoff threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery showing full charge but turbo mode collapses almost immediately\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eTurbo mode on the VEGA 1500 C+R draws significantly more current than standard or low modes. An aged or degraded Li-ion pack loses internal resistance tolerance — it reads full at rest but voltage sags sharply the moment high current is pulled. The driver interprets that voltage sag as a low-cell event and steps down or cuts out to protect the pack. Test resting voltage after a full charge: a healthy cell should read at or above 4.1V. If resting voltage is below 4.0V per cell after a full charge cycle, the pack has degraded and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377493049434,"sku":"BWCS-SGR150FT-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377493082202,"sku":"BWCS-SGR150FT-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377493114970,"sku":"BWCS-SGR150FT-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGR150FT-1.webp?v=1778767172","url":"https:\/\/batteryweb.com\/products\/scangrip-vega-1500-cr-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
