43.8V 35Ah 1533Wh Rechargeable Lithium Ion Battery Pack High Energy Density

Product Specification

43.8V 35000mAh high‑capacity drone battery

1 Product Introduction

  Built for high demand power applications this lithium ion battery module provides steady 43.8V voltage with 35Ah capacity and 1533Wh total energy. Its high weight energy density design realizes great power performance without excessive product weight. Every single battery goes through strict UN38.3 test items such as altitude simulation temperature cycling vibration shock external short circuit and crush test to greatly lower risks of leakage overheating and fire during operation and cross‑border transportation.
   We are the original factory conducting full‑range quality control for every production link from raw material selection assembly to finished product aging test. We supply complete safety paperwork including MSDS sea and land transport assessment reports to support worldwide ocean road and air delivery. This battery module features long cycle lifespan and excellent consistency among different batches. It fits various scenarios such as off‑grid energy storage industrial device power supply and heavy‑duty mobile equipment. We support large volume orders and can make targeted adjustments to satisfy your special project requirements for stable and cost effective power supplies.
