It fits the VR5000RM and VR05R5050WK alongside the PowerBot-E, all of which share the same battery bay and connector. It replaces OEM part numbers DJ81-00171A and BP14435A directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePowerBot-E, VR5000RM, VR05R5050WK compatibility:\u003c\/strong\u003e\n    These three models run on the same 14.8V four-cell Li-ion architecture and use the same connector pinout and BMS handshake protocol. One battery covers all three without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the PowerBot-E platform. The BMS communicated correctly with the dock charger, and the vacuum's suction motor drew current at the expected load profile across carpet and hard floor passes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the PowerBot-E:\u003c\/strong\u003e\n    Do not leave the PowerBot-E sitting on its dock indefinitely between uses. The dock applies a trickle charge once full, and sustained trickle current degrades Li-ion cells faster than normal cycling. Charge to full, then remove the vacuum from the dock until the next scheduled clean.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the BMS expects — usually because the filter is partially blocked. The BMS reads the spike as a low-cell condition and throttles power to protect the cells, even if the charge level is still high. The vacuum interprets reduced motor current as a battery issue, not a filter issue. Clean or replace the filter first and retest before concluding the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePowerBot-E motor cutting out mid-clean and then recovering\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip — not a dead battery. When the PowerBot-E hits a rug edge or partially blocked inlet, the motor load spikes sharply. If that spike exceeds the BMS current threshold, the battery cuts output and then resets after a few seconds once the load drops. A worn original battery triggers this more easily because aged cells have higher internal resistance. With this replacement cell at full charge, the trip threshold should only activate under a genuine blockage — check the inlet brush roll for tangled debris and verify the filter is clear.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427979788378,"sku":"BWCS-SMR510VX-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427979821146,"sku":"BWCS-SMR510VX-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427979853914,"sku":"BWCS-SMR510VX-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR510VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/samsung-powerbot-e-replacement-battery-148v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
