Product Description

For applications where recharging is infrequent or impossible, this 1S5P battery pack delivers an extraordinary 11,000mAh (40.7Wh) at 3.7V — all from five parallel-connected Grade-A 18650 cells. The all-parallel architecture keeps voltage at a safe, single-cell level while multiplying capacity 5× and slashing internal resistance to one-fifth of a single cell. The result: a battery that can trickle-charge for months on a tiny solar panel or power an IoT sensor node through an entire field season without service.
