Please check your device manual or label to confirm “7.4V \/ 2S” input.\u003c\/p\u003e\n\u003ch3\u003eThe XT30 plugs feel too tight. Is that normal?\u003c\/h3\u003e\n\u003cp\u003eYes. Brand-new XT30 connectors can be **snug on first use**. Align the keying, push straight in (no twisting), and seat\/unseat a couple of times. If you see plastic flash or debris, gently clear it—do not force the connectors.\u003c\/p\u003e\n\u003ch3\u003eWhat’s the difference between XT30 and XT30U?\u003c\/h3\u003e\n\u003cp\u003eBoth carry similar current, but **XT30U** has a revised housing\/key shape. Our pack uses **standard XT30**.

The **white 3-pin JST-XH** is the **balance\/charging lead** and should not be plugged into the model’s power socket.\u003c\/p\u003e\n\u003ch3\u003eHow do I avoid reverse polarity?\u003c\/h3\u003e\n\u003cp\u003eMatch **red-to-red (positive)** and **black-to-black (negative)**. XT30 is keyed to prevent mistakes—never force a misaligned connection.\u003c\/p\u003e\n\u003ch3\u003eHow should I charge this battery?\u003c\/h3\u003e\n\u003cp\u003eUse a charger that supports **2S (7.4V)  and balance charge via the **white JST-XH** lead. Stop charging if the pack becomes hot, swollen, or damaged.\u003c\/p\u003e\n\u003ch3\u003eCan I use this pack in place of a 2S ?\u003c\/h3\u003e\n\u003cp\u003eYes—many devices labeled “2S 7.4V” will also work with a **2S  pack, provided the connector and size fit.
