It slots into the same battery bay as the original pack and communicates with the mower's BMS over the same data line. Voltage and connector match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e82C2 platform compatibility:\u003c\/strong\u003e\n    The 82C2, KM Domus 82V, and Nimbus 82V all run the same 80V bus and use an identical battery latch and five-pin connector. One replacement covers all three without adapters or firmware changes.\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-start cycles on an 82C2 platform and monitored BMS handshake, cell voltage balance across the pack, and cutoff behaviour under sustained motor load. All cells stayed within the BMS acceptance window throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before first use of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells have higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack before it ever starts cutting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 82C2 blade motor draws a sharp inrush current every time it bites into dense or wet grass. If the pack's cells are depleted past around 30% charge, the BMS interprets that inrush spike as an overcurrent event and cuts the output to protect the cells. The mower shuts off mid-row, then restarts cleanly once you release and re-engage the blade. Keeping charge above 40% before tackling heavy sections prevents the threshold from being crossed during that startup surge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. After a full winter in an unheated garage, cell voltage can drop below the charger's acceptance threshold — typically around 2.5V per cell — causing the charger to flag a fault instead of starting a charge cycle. Some chargers on this platform have a recovery mode: connect the pack, wait 30 seconds, then disconnect and reconnect. If cell voltage is still above 2.0V per cell, the charger will usually accept the pack on the second connection and begin a slow recovery charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381303509082,"sku":"BWCS-GWP800PW-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381303541850,"sku":"BWCS-GWP800PW-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381303574618,"sku":"BWCS-GWP800PW-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP800PW-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/remarc-82c2-replacement-battery-80v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
