43.8V 35000mAh high‑capacity drone battery

1 Product Introduction

This high performance lithium ion battery module delivers consistent 43.8V output paired with 35Ah capacity and 1533Wh energy output. Constructed with premium nickel cobalt manganese raw materials the unit reaches high weight energy density to maintain steady power output under continuous heavy‑load working conditions. Every finished battery undergoes the full scope of UN38.3 safety tests including altitude simulation thermal cycling vibration mechanical shock external short circuit and crush tests to mitigate risks of leakage swelling and ignition both in operation and transit.
We are the original manufacturer with end‑to‑end production control from incoming material inspection to final product validation. Full sets of safety files including MSDS sea transport and land transport identification reports are available to support global shipping via ocean road and air transport. This battery module features extended cycle life and excellent performance consistency across production batches. It works well for off‑grid energy storage industrial equipment power supply and various heavy‑duty device projects. We accept large volume orders and can adjust specifications to fit your unique project needs for stable cost‑efficient power solutions.
