Product Overview
The BAKTH-523450AR-1S-2P is a compact, high‑capacity lithium‑ion battery pack built with a 1S2P (one series, two parallel) configuration using premium 523450AR pouch cells. It delivers a stable 3.7V nominal voltage and a combined 2200mAh capacity – approximately 8.14Wh of energy. Measuring just 6.1mm thick × 52mm wide × 73mm long, this pack balances thinness with substantial runtime, making it ideal for smart watches, fitness trackers, GPS devices, portable medical monitors, and IoT sensors. 

 

Key Features & Benefits

• 2P Parallel Design for Double Capacity
  Two 1100mAh cells connected in parallel deliver 2200mAh total capacity, effectively doubling the runtime of a single cell while maintaining the same 3.7V voltage. Lower internal resistance also improves efficiency and reduces heat.

• 8.14Wh Energy Reserve
  With 2200mAh capacity, this pack provides ample power for extended use – enough for several days of operation in low‑power wearables or hours of continuous use in medical monitors.

• Thin 6.1mm Profile
  Despite the double‑cell design, the pack maintains a slim 6.1mm thickness, allowing integration into space‑constrained product enclosures without compromising battery life.

• Grade‑A Pouch Cells
  Manufactured with high‑quality, Grade‑A lithium polymer cells, offering low self‑discharge, stable voltage output.

• Built‑in Protection Circuit (PCM)
  Integrated protection safeguards against over‑charge, over‑discharge, and short circuits, ensuring safe and reliable operation.

• Flexible Integration Options
  Supplied as a bare cell pack with pre‑welded nickel tabs (standard) or optional wire harness / connectors for OEM orders.
