Description

The THOR-18650-1S1P-2600 is a finished 3.7V 2600mAh lithium-ion battery pack built from a single THOR-18650-26E NMC cell (1S1P), with an integrated PCM, PH2.0 connector and 80 mm leads. At 9.62 Wh it stays well under the 100 Wh air-freight threshold, so it ships without full Class 9 dangerous-goods handling.

THOR Power builds this pack to your specification — cell choice, PCM current limit, NTC thermistor, wire length, connector and custom labelling. Tell us your target voltage, runtime and discharge current, and our engineers will size the pack for you.

  • Assembled and tested pack — 3.7 V nominal, ready to fit
  • Tier-1 cells, capacity and internal-resistance matched
  • PCM included: overcharge, over-discharge, short-circuit protection
  • Connector, wire length, NTC & custom labelling to your spec
  • UN38.3 / MSDS ready; CE, KC, ROHS on request
