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.\u003c\/p\u003e \u003ch4\u003eApplications \/ Uses\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eHigh-capacity flashlights and portable lighting rigs designed for protected button top 21700 cells\u003c\/li\u003e \u003cli\u003eConsumer electronics and personal devices requiring button top 21700 format with PCB protection\u003c\/li\u003e \u003cli\u003ePortable power banks and single-cell devices where overcharge and over-discharge protection are required\u003c\/li\u003e \u003cli\u003eMedical and industrial handheld equipment requiring long-runtime protected lithium-ion power\u003c\/li\u003e \u003cli\u003eButton top 21700 replacements where 5700mAh capacity and cell-level protection are both priorities\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eSpecifications\u003c\/h4\u003e \u003cdiv class=\"table-wrapper\"\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e\n\u003ctd\u003eBrand:\u003c\/td\u003e\n\u003ctd\u003eEVE Energy\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eModel:\u003c\/td\u003e\n\u003ctd\u003eINR21700-58E\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Type:\u003c\/td\u003e\n\u003ctd\u003e21700 Lithium-Ion\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eNominal Capacity:\u003c\/td\u003e\n\u003ctd\u003e5700mAh\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMinimum Capacity:\u003c\/td\u003e\n\u003ctd\u003e5600mAh\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eNominal Voltage:\u003c\/td\u003e\n\u003ctd\u003e3.6V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Charge Voltage:\u003c\/td\u003e\n\u003ctd\u003e4.20V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDischarge Cut-off Voltage:\u003c\/td\u003e\n\u003ctd\u003e2.5V\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Discharge Current:\u003c\/td\u003e\n\u003ctd\u003e16.8A\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eStandard Charge Current:\u003c\/td\u003e\n\u003ctd\u003e1.12A (CCCV)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Charge Current:\u003c\/td\u003e\n\u003ctd\u003e5.6A\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eProtected:\u003c\/td\u003e\n\u003ctd\u003eYes (PCB) — overcharge, over-discharge, over-current, short circuit\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eBattery Top:\u003c\/td\u003e\n\u003ctd\u003eButton Top\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eCharge Temperature:\u003c\/td\u003e\n\u003ctd\u003e0°C to 45°C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDischarge Temperature:\u003c\/td\u003e\n\u003ctd\u003e-20°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eApprox.
