3.7V 18500 Lithium Battery Pack | 800mAh-1400mAh High Capacity Rechargeable Battery for E-Scooters & Power Tools

We’ve been moving these 18500 packs for years now, and the thing that usually gets people’s attention first is the 500 charge cycles—that’s roughly two to three years of daily use depending on how deep you drain them, and it holds up better than a lot of teh cheaper cells we see coming through.

Basically, what it does is it gives you a solid 3.7V nominal with a capacity range form 800mAh up to 1400mAh, so if you’re building a battery for an e-scooter or a power tool, you can pick the sweet spot for your runtime without overspending on capacity you don’t need.

For our buyers in the US and EU, we make sure every shipment comes with the full ISO9001 and SGS documentation—COAs, SDS, the whole package—so customs clearance is pretty straightforward, and we usually have stock on the flat top terminals unless you need a custom tab, in which case just give us a heads up (check lead time, typically 2-4 weeks).

Now, one thing that catches some folks off guard is the operating tempearture range—it runs from -20°C to 68°C, which is fine for most outdoor gear but you wouldn’t want to push it into a hot engine bay long-term, and the 18mm by 50mm dimensions mean it fits nicely into handheld tools without being too chunky.

Also, the max discharge current is 1C, so for a 1400mAh cell that’s about 1.4 amps continuous—that’s plenty for a portable fan or a small motor controller, but if you’re looking at high-drain application like an e-bike pulling 20 amps, you’ll want a different form factor, no question about it.

We’ve shipped these to the UK as well, and ROHS compliance is, so import docs are never an issue—just let us know the capasity you need, and we’ll match it from the 800mAh to 1400mAh range, with a shelf life of about 5 years if stored properly.
