Apsenx 11.1V 850mAh lithium polymer cell battery is built for devices that need something small, steady, and safe. We use high-quality cobalt-based materials, so the battery runs smoother and holds up better over time. Safety isn’t an afterthought either—overcharge, over-discharge, short-circuit, and overcurrent protection are all included.

Before shipping, every battery is checked one by one—capacity, voltage, size, internal resistance, charge current limits, discharge cut-off, all of it. Lead time is quick too: samples in about 4–7 days with DHL/UPS door-to-door.

If you’re buying for production, wholesale, or want your own branded version, we offer full OEM/ODM support—from battery design to packaging and final shipment.
