Built upon high\u2011energy\u2011density 21700 lithium\u2011ion cell technology, the BAKTH\u2011INR21700P42A\u20111S\u20113 is a 1\u2011series standalone battery solution delivering 3.6V nominal voltage, 4.2Ah usable capacity and 15.12Wh total energy. Different from connector\u2011terminated battery assemblies, this unit comes with exposed tinned wire ends, granting your engineering team full freedom to decide terminal types, cable length and wiring layout during your product development cycle. This open\u2011ended configuration is perfectly suited for OEM integrators who carry out custom internal wiring inside finished devices.<\/div>\n<\/div>\n
\n
Fully validated for worldwide distribution, this single\u2011cell pack holds three core international compliance documents, including IEC62133 lithium\u2011ion safety certification, UN38.3 transportation test approval, and RoHS environmental compliance. These complete credentials cut down your compliance research workload, streamline overseas customs clearance and regulatory inspections, making mass export of your end\u2011products toward Europe, North America and other global markets far less complicated. It delivers consistent, ripple\u2011free power output across a broad\u2011range operating temperature of \u201120\u2103 to 60\u2103, adapting to handheld gadgets, indoor fixed sensors and semi\u2011outdoor low\u2011power monitoring hardware.<\/div>\n<\/div>\n
\n
An integrated compact BMS protection circuit is embedded inside the battery pack. It actively monitors cell status and delivers multi\u2011level protection against over\u2011charge, over\u2011discharge and accidental short\u2011circuit faults, protecting cell health and extending the overall service life. This 21700 battery supports a maximum charge current of 3A for faster recharge cycles, with max charging voltage capped at 4.2V and discharge cut\u2011off voltage set to 2.8V. The stranded bare wire leads can be easily soldered or crimped onto your custom terminals, offering maximum wiring flexibility for your internal hardware design.<\/div>\n<\/div>\n
\n
With compact cylindrical form\u2011factor, its maximum outer dimension measures 73mm(L) \u00d7 25mm(W) \u00d7 22mm(H), and the battery weighs merely 73g. Thanks to 21700 cell\u2019s upgraded energy density compared to traditional 18650 cells, you can obtain higher capacity without dramatically expanding battery physical size. The lightweight build helps you achieve weight\u2011reduction goals for your portable, battery\u2011powered finished goods.<\/div>\n<\/div>\n
\n
We provide multiple procurement options for hardware developers, system integrators and bulk\u2011order industrial buyers. You can choose standard BAKTH\u2011branded battery packs, unprinted neutral units without logo, or request full\u2011scope OEM customization: wire\u2011length adjustment, terminal soldering, custom label printing and fine\u2011tuning of BMS protection thresholds. Every production batch undergoes charge\u2011discharge cycle aging and capacity\u2011sorting testing before shipment, ensuring tight capacity consistency for your large\u2011scale manufacturing deployment.<\/div>\n<\/div>\n
