Replacement battery for Thor VM3

This lithium-ion pack replaces the original Thor VM3 battery using part numbers 50139885-001, OVT270L1R00, 50121692-001, L3-52301624A-R and OVT270L1R01. It supplies 7.4V and 5200mAh for 38.48Wh of capacity. The pack is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. It is intended for users who need a direct replacement for a depleted or lost original cell.

Build and daily handling

The battery measures 132.5 x 42.5 x 19.0mm and weighs 320.0g, matching the factory form factor so it seats without adapters. A single pack ships in the box. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are integrated. RoHS approval confirms the absence of restricted substances. Buyers who need a multi-pack or a different voltage should look elsewhere.

Thermals, noise and power draw

The cell operates silently with no moving parts. Normal use stays within the 7.4V nominal rating and the 38.48Wh energy budget. Protection circuits limit current during fault conditions. No active cooling is required. The pack is not suited for applications that demand a higher voltage or a different chemistry.
