Jaycar 14500 LiFePO4 Battery 600mAh 3.2V – Unprotected Cell with ~2000 Cycle Life

You've been through three or four Li-Ion cells in a year and the capacity keeps dropping. That's normal for standard Li-Ion — 500 to 1,000 cycles is about all you get before it feels weak.

This Jaycar 14500 LiFePO4 cell changes that math. Around 2,000 charge cycles, higher peak current delivery, and a chemically more stable chemistry that doesn't degrade the same way. You trade a bit of capacity (600mAh vs 800mAh) and a slightly lower nominal voltage (3.2V vs 3.7V), but you get a cell that lasts years longer on the shelf.

Same warning applies: this is an unprotected cell. No BMS inside. If your device or charger spec calls for a protected cell, do not use this one. Check the manual first.

Add to cart when you're done cycling through short-life Li-Ion packs

• ~2,000 charge/discharge cycles — roughly double the life of a standard 14500 Li-Ion cell
• 600mAh at 3.2V nominal (LiFePO4 chemistry), slightly lower than equivalent Li-Ion but more stable
• Delivers higher peak currents than a comparable Li-Ion cell in the same 14500 form factor
• Unprotected cell: no internal BMS — must be paired with a compatible charger and device housing
• Chemically more stable than traditional Li-Ion, reducing thermal risk under normal use
