EVE 58E 21700 5700mAh 16.8A Protected Button Top

Key Features 5700mAh Ultra-High Capacity: Built on the original EVE INR21700-58E cell with a nominal capacity of 5700mAh and 5600mAh minimum rating, delivering exceptional runtime for extended-use applications in compatible button top devices. 16.8A Maximum Discharge Capability: Supports up to 16.8A maximum discharge current for reliable, stable power output across compatible single-cell and multi-cell device applications. PCB Protection Circuit: Integrated protection circuit board provides overcharge, over-discharge, over-current, and short circuit protection for safe operation in compatible devices without the need for an external BMS. Button Top Terminal: Positive button top configuration ensures broad compatibility with devices designed for button top 21700 cells — note that this cell is physically longer than a standard flat top unprotected 21700 battery due to the added PCB and button top terminal. Wide Operating Temperature Range: Supports charging from 0°C to 45°C and discharge from -20°C to 60°C for reliable performance across a broad range of operating environments. Note: This is a button top protected 21700 battery which is longer than a standard flat top unprotected 21700 battery. Overview This EVE INR21700-58E Protected Button Top battery pairs the original EVE 58E flat top 21700 cell with an added button top terminal and PCB protection circuit, creating a protected button top cell suited for compatible devices requiring both button top format and cell-level safety protection. Delivering a nominal capacity of 5700mAh at 3.6V nominal voltage with a maximum continuous discharge of 16.8A, the 58E offers high-capacity performance for flashlights, consumer electronics, and portable devices designed for the 21700 button top format. The integrated PCB protects against overcharge, over-discharge, over-current, and short circuit conditions. Standard charge current is 1.12A via CCCV method, with a maximum charge current of 5.6A. This protected button top cell is physically longer than a standard flat top unprotected 21700 battery — always verify dimensional compatibility with your device before purchase. Do not remove the protective wrap, as doing so may compromise the protection circuit. Applications / Uses High-capacity flashlights and portable lighting systems designed for protected button top 21700 cells Consumer electronics and personal devices requiring button top 21700 format with built-in cell-level protection Portable power banks and single-cell devices benefiting from PCB overcharge and over-discharge protection Medical and industrial handheld devices requiring stable, protected lithium-ion power with high capacity Replacement cells for compatible button top 21700 devices where high capacity and protection are both required Specifications Brand: EVE Energy Model: INR21700-58E Battery Type: 21700 Lithium-Ion Nominal Capacity: 5700mAh Minimum Capacity: 5600mAh Nominal Voltage: 3.6V Maximum Charge Voltage: 4.20V Discharge Cut-off Voltage: 2.5V Maximum Discharge Current: 16.8A Standard Charge Current: 1.12A (CCCV) Maximum Charge Current: 5.6A Protected: Yes (PCB) — overcharge, over-discharge, over-current, short circuit Battery Top: Button Top Charge Temperature: 0°C to 45°C Discharge Temperature: -20°C to 60°C Approx.
