It carries a 2600mAh (9.62Wh) capacity and slots into the same position as the original YBP-L01 cell. If your NX-P100 no longer holds charge or cuts out mid-session, this cell restores it to normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNX-P100 compatibility:\u003c\/strong\u003e\n    The NX-P100 uses a single Li-ion cell running at 3.7V nominal to power both the Bluetooth radio and the Class D amplifier from one shared rail. The YBP-L01 matches the original cell's voltage, capacity, and connector pinout — no adapter required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the NX-P100 platform and confirmed the BMS accepted the pack without fault flags. Charge termination triggered correctly at full voltage, and the protection circuit tripped cleanly at low-cell threshold before the amplifier stage starved.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after swap:\u003c\/strong\u003e\n    After fitting this cell, run the NX-P100 down to auto-shutoff on first use, then charge uninterrupted to 100%. The speaker's onboard fuel gauge recalibrates to the new cell's capacity curve — skipping this step causes the indicator to read inaccurately for weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the NX-P100 audio drops before the battery indicator hits empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt high playback volume, the Class D amplifier and Bluetooth radio draw simultaneously, spiking current demand sharply. A degraded or shallow-cycled cell can't sustain voltage under that combined load — the cell voltage sags below the amplifier's minimum operating threshold before the fuel gauge registers low. The speaker interprets this as normal operation and doesn't warn you. Fitting a fresh 2600mAh cell raises the sag floor, giving the amplifier enough headroom to reach true low-battery cutoff without clipping first.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNX-P100 won't wake from USB charge after sitting unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month. After several months in storage, the NX-P100's cell can drop below the USB-C acceptance threshold — the charger sees a pack voltage it won't engage with, so the speaker appears completely dead. Some units recover with a bench supply trickle at 3.0V for 10–15 minutes to bring the cell above the USB-C PD floor, then plug into USB normally. If the cell has dropped below 2.5V and held there for an extended period, recovery is unlikely and replacement is the correct next step.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416204705882,"sku":"BWCS-YNX100SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416204738650,"sku":"BWCS-YNX100SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416204771418,"sku":"BWCS-YNX100SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YNX100SL-1.webp?v=1779760792","url":"https:\/\/batteryweb.com\/products\/yamaha-nx-p100-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
