EVE 58E 21700 5700mAh 16.8A Protected Button Top

Key Features 5700mAh Ultra-High Capacity: The EVE 58E is one of the highest-capacity 21700 cells available — 5700mAh nominal, 5600mAh minimum, now in a protected button top format ready for compatible devices. 16.8A Maximum Discharge Capability: 16.8A maximum discharge gives this cell solid current headroom for flashlights, electronics, and other single-cell applications that need reliable output. PCB Protection Circuit: Built-in PCB covers overcharge, over-discharge, over-current, and short circuit — use it in compatible devices with confidence and without needing an external BMS. Button Top Terminal: Positive button top for broad device compatibility — just keep in mind this cell runs longer than a standard flat top unprotected 21700, so check your battery compartment dimensions before ordering. Wide Operating Temperature Range: Charges from 0°C to 45°C and discharges from -20°C to 60°C — built for real-world conditions across a wide range of environments. Note: This is a button top protected 21700 battery which is longer than a standard flat top unprotected 21700 battery. Overview The EVE 58E is already one of the most capable high-capacity 21700 cells on the market, and this protected button top version makes it accessible for devices that require button top format with built-in cell protection. At 5700mAh nominal capacity and 16.8A maximum discharge, it delivers serious runtime and enough current for demanding flashlights, electronics, and portable devices designed for 21700 button top cells. The integrated PCB handles overcharge, over-discharge, over-current, and short circuit protection at the cell level. Standard charge is 1.12A via CCCV, with a 5.6A fast charge option. One thing to check before ordering: the added button top and PCB make this cell longer than a standard flat top unprotected 21700 — confirm your device's battery compartment can accommodate it first. Keep the protective wrap on; removing it can compromise the protection circuit. Applications / Uses High-capacity flashlights and portable lighting rigs designed for protected button top 21700 cells Consumer electronics and personal devices requiring button top 21700 format with PCB protection Portable power banks and single-cell devices where overcharge and over-discharge protection are required Medical and industrial handheld equipment requiring long-runtime protected lithium-ion power Button top 21700 replacements where 5700mAh capacity and cell-level protection are both priorities 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.
