Molicel INR-18650-P30B 3.6V 3000mAh 10C Li-Ion Cell

The Molicel INR-18650-P30B is a high-drain 18650 lithium-ion cell for building long-range FPV, fixed-wing and UAV battery packs where endurance matters more than outright punch. It combines 3000 mAh of capacity with a high continuous current rating and low internal resistance, so packs hold their voltage under cruise and climb loads.

Key features

• 3000 mAh at 3.6 V nominal, giving 10.8 Wh per cell
• 10C (30 A) working discharge rating, with Molicel specifying up to 36 A maximum continuous discharge
• Low DC internal resistance of about 15.4 mΩ limits voltage sag and heat
• Fast-charge capable at up to 9 A, per Molicel's rating
• Rated for 500 cycles to 75% capacity retention

Specifications

• Format: 18650 cylindrical
• Chemistry: Li-ion
• Nominal voltage: 3.6 V
• Nominal capacity: 3000 mAh (10.8 Wh)
• Max continuous discharge: 36 A
• Max charge current: 9 A

• Cycle life: 500 cycles to 75% capacity

This is a bare, unprotected cell: build packs by spot-welding nickel strip rather than soldering, fit balance leads, and charge on a balance charger set to Li-ion at 4.2 V per cell. As a sizing guide, a 6S1P pack gives 21.6 V nominal and 3000 mAh, and 6S2P doubles that to 6000 mAh along with the current headroom.
