A fully depleted Li-Polymer cell left in storage can drop below the BMS recovery threshold, which will prevent the remote from powering on at all — even after plugging in to charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Nevo SL won't turn on after a new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell shipped at partial charge may sit just below the SL's minimum startup voltage if it was stored for a long time in transit or in a warehouse. The remote's protection circuit blocks power-on until the cell reaches a safe operating threshold. Connect the Nevo SL to its charger for 15–20 minutes before attempting to power it on. Once the cell clears approximately 3.5V, the BMS will release and the remote will boot normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIR range drops noticeably before the battery reads as low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nevo SL's IR LED requires a consistent current burst to fire a strong signal. As the Li-Polymer cell ages and its internal resistance rises, voltage sags under the brief high-current demand of each IR pulse — even if the resting voltage still looks acceptable. The remote's display may show a normal battery indicator while the effective control range has already shortened significantly.
