INR21700PL‑5000mAh Full‑Tab 21700 Lithium‑Ion Cell

Product Overview

Our full tab 21700 lithium ion cell, model INR21700PL‑5000mAh, is a premium A‑grade wholesale 21700 battery cell. This high drain 21700 cell uses full‑tab construction built for heavy‑duty battery pack projects, made by Henan Yichuan New Energy.

This NCM cylindrical cell features ultra‑low internal resistance and strong high‑current output. It delivers 5000mAh capacity with stable heavy‑load performance for custom battery pack assembly. We keep large bulk inventory with competitive wholesale pricing.

Key Performance Highlights

• Full‑tab high‑rate design: peak short‑term discharge up to 12C (60A) with thermal cut‑off at 80℃. Continuous discharge up to 3C when ambient temperature ≥10℃.
• 5000mAh nominal capacity, minimum capacity 4950mAh. Stable output under high current loads.
• 3C fast‑charge support at proper ambient temperature. Max charging current de‑ranges automatically at low temperature for cell safety.
• Wide operating temperature range: charge from ‑10℃ to 50℃; discharge from ‑40℃ to 60℃. Reliable performance in cold and hot environments.
• Decent cycle stability: reach ≥80% initial capacity after 1000 cycles under 8A charge /10A discharge condition.
• Qualified safety performance: pass vibration, drop, crush, over‑charge, short‑circuit, 130℃ hot‑oven and thermal cycling safety tests.
