LINKDATA 21700S-65P BATTERY CELL – 6500MAH 52A – HIGH CAPACITY HIGH POWER

The Linkdata INR21700S-65P combines a typical capacity of 6500mAh with a 52A maximum continuous-discharge rating subject to the manufacturer’s 80°C temperature cutoff. With 23.4Wh typical energy at 3.6V nominal, it provides high energy capacity in a single 21700 lithium-ion cell for engineered battery packs.

Sold individually as one unprotected cell. The finished pack or device must provide suitable charging, current and temperature protection. Check the wrapped cell dimensions against your holder or enclosure before purchase.

FEATURES:

• 6500mAh typical capacity and 23.4Wh typical energy per cell.
• 52A maximum continuous-discharge rating with an 80°C temperature cutoff; thermal monitoring is required and available capacity depends on load and temperature.
• 21700 cylindrical format with a flat positive terminal.
• Standard 3.25A CC-CV charging; maximum continuous charge current 8A within manufacturer limits.
