High-Quality 18650 Rechargeable Lithium-Ion Battery for Power Tools and Consumer Electronics

So basically it's a lithium-ion cell in the common 18650 format that also comes as AA, AAA, or 9V — we just run the same NCM chemistry inside whichever shell you need.

Cycle life is 1000+ cycles, which is better than most consumer-grade cells that give up around 500 or so, but keep in mind that's under ideal lab conditions and real-world use might drop it to 700-800 depending on your discharge depth.

We've got CE, ROHS, MSDS, and UN38.3 certs, but what actually matters for shippng is UN38.3 — without it, you're stuck with ground transport only, and we always include a copy with every batch.

One thing I've learned handling these is that the USB-C charging port is actually pretty handy for field use on power tools, but if you're running high-drain devices you'll still want a proper charger for full current (the USB tops out at about 1A). The 5L drum is easier to handle for smaller orders but 25L is cheaper per unit if you're doing a full production run.

You'll order with a PO and we'll send a proforma invoice — typical MOQ is 500 pieces for custom branding (color, sleeve logo, packaging), no, we don't often stock odd voltages like 18750 or non-standard capacities unless you're ordering a few thousand.

Most customers just grab teh 2000mAh option for power tools and the 3000mAh for vape pens, but for something that isn't suited for ultra-high discharge like 30A continuous, the 1500mAh version with lower internal resistnce is actually tighter tolerance than most generics for that use case.
