43.8V 35Ah 1533Wh Rechargeable Lithium Ion Battery Module 290Wh/kg High Energy Density Battery Pack Factory Direct OEM Bulk Supply Energy Storage Industrial Heavy‑Load Power Applications

43.8V 35000mAh high‑capacity drone battery

1 Product Introduction

  Robust lithium‑ion battery module offers steady 43.8V power output, 35Ah rated capacity and 1533Wh total energy, built with premium cathode‑anode materials for superior energy density and stable power delivery. Each unit undergoes comprehensive UN38.3 safety validation covering altitude simulation, temperature variation, vibration, mechanical shock, external short‑circuit and crush assessments to prevent leakage, swelling or fire hazards during operation and transportation.
  As direct manufacturer, we control the full production workflow from raw‑material inspection to finished‑product testing. Complete safety documentation including MSDS, sea and land transport classification reports are provided to facilitate worldwide shipping by ocean, truck or air. Featuring long service life and stable cyclic performance, this battery module fits diverse use‑cases: off‑grid energy storage systems, industrial equipment power supply and heavy‑duty mobile devices. Consistent batch‑to‑batch quality is guaranteed. We welcome bulk orders and tailored modifications to match your unique project requirements for reliable, cost‑effective energy solutions.
