Product Description
The 18650 Red 3.7V Li-ion Battery (Button Top) is an economical power solution for high-volume prototyping and student projects. Its button top terminal ensures reliable electrical contact in battery holders, flashlights and emergency lighting systems where flat-top cells often fail. This is a clone/recycle lithium-ion cell — a budget-friendly, reusable energy source for non-critical electronics. Note: actual capacity, internal resistance and lifespan may vary between batches and individual cells. For best results in multi-cell packs, test and match individual cells, and always use a dedicated Li-ion protection module (BMS) to prevent over-discharge. Use only with compatible chargers and avoid high-drain professional equipment.
