It replaces OEM part numbers WG-MRK7005A-ET and BAT7000C. Fit this when the original pack no longer holds a charge or the mower fails to complete a scheduled cutting cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR.S.400 \/ R.S.600 \/ Loopo M2000 platform fit:\u003c\/strong\u003e\n    These models share the same 25.6V battery rail, physical housing, and BMS communication protocol. One pack covers the full group — no adapter or firmware workaround needed.\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 Wolf Garten compatible BMS rig. The protection circuit responded correctly to over-discharge cutoff and the cell balancing held within spec across five cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSpring recommissioning 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 carry higher internal resistance, and the blade motor inrush current on a cold pack can trip the BMS before the mower leaves the dock.\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 passes\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe blade motor on the R.S.400 draws a brief inrush surge each time it bites into dense or damp grass. If the battery's state of charge is below roughly 20%, the BMS reads the voltage sag from that inrush as a fault condition and cuts output to protect the cells. The mower stops mid-row, returns to the dock, and reports a battery or motor error. Running the first few cuts on a freshly charged pack — above 24V resting — prevents most of these nuisance trips.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows fault light after mower sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month in storage. After a full winter, a pack stored without a top-up charge can drop below the charger's acceptance threshold — typically around 20V for 25.6V chemistry. The charger sees a voltage it treats as a damaged or deeply discharged cell and refuses to start a charge cycle. Some Wolf Garten chargers support a recovery or wake mode — consult the charger manual for the activation sequence, then watch for the charge LED to switch from fault to active within two minutes. If the pack doesn't respond, check resting voltage with a multimeter; anything above 18V is usually recoverable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381312684122,"sku":"BWCS-RCT300VX-1","price":219.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381312716890,"sku":"BWCS-RCT300VX-2","price":260.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381312749658,"sku":"BWCS-RCT300VX-3","price":291.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RCT300VX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/wolf-garten-rs400-replacement-battery-256v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
