It slots into the same battery bay as the original and connects to the projector's onboard BMS through the same multi-pin interface. Voltage and capacity match the original cell specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePH150 and PH150G compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS communication protocol — one cell fits either unit without modification or adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the battery through charge and discharge cycles on the PH150 platform. The BMS handshake completed correctly, charge termination triggered at the right voltage, and the projector reported battery status accurately through all states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLamp brightness and draw management:\u003c\/strong\u003e\n    Set the PH150 to eco brightness mode when running on battery. Full brightness draws 30–40% more current from the cell than eco mode — the projector's LED driver pulls harder, which stresses the cell and reduces available runtime without a visible quality difference in most presentation environments.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PH150 shuts off before the battery indicator reaches empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PH150's LED lamp assembly requires a minimum supply voltage to sustain stable light output — typically above the battery's official low-voltage cutoff. When the cell voltage drops under load to that lamp threshold, the projector kills power to the lamp even though the battery gauge still shows remaining charge. This is a firmware-level protection to prevent an unstable lamp arc, not a fault in the battery. It becomes more noticeable in cold environments or with an aged cell that sags harder under the lamp's current draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery shows full charge but projector won't start\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the BMS has entered a protection state — often triggered by a deep discharge that dropped cell voltage below the recovery threshold. The projector's charge circuit may not supply enough current to wake a deeply discharged cell on its own. Connect the projector to mains power and leave it for 20–30 minutes before attempting to power on; the charger needs time to trickle-charge the cell back above approximately 3.0V per cell (6.0V pack) before the BMS unlocks normal operation. If the battery still shows no response after that, check the connector pins for oxidation and reseat the pack firmly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416087658586,"sku":"BWCS-LPH150PT-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416087691354,"sku":"BWCS-LPH150PT-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416087724122,"sku":"BWCS-LPH150PT-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LPH150PT-1.webp?v=1779760241","url":"https:\/\/batteryweb.com\/products\/lg-ph150-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
