It slots into the same battery port as the original pack and communicates with the mower's existing BMS handshake. Voltage and cell count match the 82V platform specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e82C2, KM Domus 82V, and Nimbus 82V platform fit:\u003c\/strong\u003e\n    These three models share the same 80V battery rail, connector housing, and BMS communication protocol. One pack covers all three without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through simulated blade-motor inrush draws on the 82V platform. The BMS held under normal load cycling and responded correctly to thermal cutoff conditions without nuisance trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first mow of the season, bring this battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current on startup can trip the BMS on a cold pack before it ever reaches full power.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff under thick grass or wet-lawn blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 82V blade motor draws a large inrush current every time it bites into dense or wet grass. If that spike exceeds the BMS overcurrent threshold — which sits lower when cells are already warm — the pack shuts down as a protection measure. This is not a fault with the battery. Let the pack rest for five minutes, then resume mowing at a slower walking pace through the heavy section. Keeping blade speed consistent reduces the amplitude of those current spikes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows fault light after the mower sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. After months in a cold garage, a pack can drop below the charger's minimum acceptance voltage — typically around 60V on the 82V platform — and the charger interprets it as a damaged cell and throws a fault. To recover, try a different compatible 82V charger if one is available, as some units have a recovery mode that pulses low current until the pack climbs back above the acceptance threshold. If the pack reaches approximately 65V, the standard charger should take over and complete the charge normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381304164442,"sku":"BWCS-GWP800PX-1","price":150.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381304197210,"sku":"BWCS-GWP800PX-2","price":178.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381304229978,"sku":"BWCS-GWP800PX-3","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP800PX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/remarc-82c2-replacement-battery-80v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
