INR21700-50SG
Dependable energy for moderate-power systems.
A 5,000 mAh 21700-format cell with a 20 A maximum continuous discharge rating, suited to battery systems that prioritise energy delivery, runtime and efficient thermal operation.
An energy-focused choice for moderate load profiles.
Choose this cell when the application values runtime and stored energy more than extreme current capability. Its 5,000 mAh capacity and 20 A discharge rating suit moderate-power 21700 pack designs, subject to complete electrical and thermal validation. Its 253 Wh/kg gravimetric energy density provides a clear basis for comparing it with other cells in the portfolio.
Capacity supports useful operating time between charges.
Well matched to verified loads below high-power extremes.
Relevant to custom packs and broad distributor portfolios.
