It slots into the same bay as the original pack and communicates with the mower's onboard BMS over the same connector. Voltage and capacity figures are drawn directly from ENVIRO's product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEP3620 \/ EP3630 \/ EP3640 platform compatibility:\u003c\/strong\u003e\n    These three part numbers share the same 60V cell architecture, connector pinout, and BMS handshake protocol. ENVIRO uses them interchangeably across mower variants in this voltage class, so one replacement covers all three OEM designations.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through blade-start inrush events and sustained cutting loads. The BMS handled repeated motor-start current spikes without tripping, and cell voltage held steady across a full discharge cycle under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal start-up tip:\u003c\/strong\u003e\n    Before the first mow of the season, bring the 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 a cold pack can trip the BMS before the mower even completes a single row.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during thick-grass or wet-grass cutting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen blade load spikes — dense clippings, wet grass, or a patch of overgrown turf — the motor draws significantly more current than it does on a clean, dry lawn. If that inrush exceeds the BMS protection threshold, the pack shuts output down immediately to prevent cell damage. This is not a battery fault; it is the protection circuit working correctly. Raise the deck height by one notch before tackling heavy sections, and allow the pack to sit off the mower for two minutes before restarting — internal temperature needs to drop below the thermal reset point first.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion packs self-discharge slowly during storage. If the pack sat all winter without a top-up charge, cell voltage may have dropped below the charger's acceptance threshold — typically around 2.5V per cell. A charger that sees voltage below that level reads the pack as faulty and refuses to initiate a charge cycle. Some ENVIRO chargers include a recovery mode: hold the charge button for five seconds to force a low-current trickle that brings cells back above the acceptance voltage, then allow the normal charge cycle to complete.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381285912666,"sku":"BWCS-WEG361PX-1","price":211.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381285945434,"sku":"BWCS-WEG361PX-2","price":251.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381285978202,"sku":"BWCS-WEG361PX-3","price":281.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WEG361PX-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/enviro-replacement-battery-60v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
