It’s 3.7V 1500mAh spec, suitable for flashlights, laptop power banks, and portable devices without any issues. Small size, light weight, and more space-saving and durable than lead-acid, Ni-Cd, or Ni-MH batteries.

With normal use, getting 800–1000 cycles is no problem. Apsenx can also help you build custom lithium battery packs, with short lead times and even higher energy density if needed. Lightweight, low self-discharge, and well-designed safety features.

We can build lithium batteries in different sizes, capacities, or structures according to your project requirements. Before shipping, every single cell goes through full inspection—capacity, voltage, impedance, size, weight, everything is checked.

Logistics are flexible too, and we ship worldwide. Most deliveries go by DHL or UPS, taking about 4–7 days to reach you.

Apsenx has been supplying customers globally for years and supports OEM and ODM. If you need private labeling or a complete solution, we can handle everything—from cell design and structure to packaging and transportation.

Each battery pack goes through full functional testing before shipment: capacity, voltage, impedance, max discharge current, cut-off voltage… every item is measured properly.

The battery itself includes a complete protection structure, including a safety valve, anti-explosion design, and bottom insulation layers. The shell is full steel—corrosion-resistant, impact-resistant, and won’t short-circuit from bumps, making it safer than common casings.

Compatibility is wide—as long as your device runs on 3.7V and uses 18650 cells, this battery will basically fit. It’s stable, safe, and helps protect your device from battery-related failures.
