\n
Built upon a 2\u2011cell parallel configuration, the BAKTH\u201118650CA\u20112P\u20113J lithium\u2011ion pack strikes a well\u2011balanced sweet spot between compact footprint and extended runtime, perfectly engineered for product designers who wish to upgrade device endurance without drastically expanding internal enclosure volume. This battery delivers a nominal rating of 3.7V, 4500mAh, storing 16.65Wh of usable energy to drastically cut down recharge frequency for portable electronics.<\/div>\n<\/div>\n
\n
The on\u2011board battery management circuit forms a comprehensive safety barrier, actively shielding the battery unit against over\u2011charging, deep over\u2011discharging and short\u2011circuit hazards during day\u2011to\u2011day operation. Its electrical working parameters are optimized for gentle, low\u2011stress charging cycles: a maximum charging voltage of 4.2V, 2.8V low\u2011voltage cut\u2011off threshold and a recommended safe maximum charge\u2011current of 2A. Its broad operational temperature window of\u201120\u2103\u201160\u2103 allows finished equipment to run reliably in variable indoor, workshop and semi\u2011outdoor environmental settings.<\/div>\n<\/div>\n
\n
Every batch of finished battery packs undergoes strict third\u2011party compliance testing before release. Valid IEC62133 cell safety certification, UN38.3 transport approval and RoHS hazardous\u2011substance compliance documentation are provided. This complete certification package removes major logistical obstacles for international wholesalers, original equipment manufacturers and system integrators shipping battery\u2011powered goods across multiple customs territories.<\/div>\n<\/div>\n
\n
Measuring at maximum 70mm \u00d7 38mm \u00d7 19mm and weighing merely 100g, this lightweight rectangular battery pack can easily fit inside narrow\u2011bodied handheld hardware. It comes pre\u2011assembled with color\u2011coded leads and a standard white 3\u2011pin connector for instant installation. Our in\u2011house customization service covers wire\u2011length adjustment, connector replacement, pin definition modification and custom sticker printing, allowing you to achieve seamless hardware compatibility without costly PCB redesign.<\/div>\n<\/div>\n
\n
We establish flexible long\u2011term bulk\u2011supply partnerships for B\u2011sector industrial buyers. Three branding solutions are available: original BAKTH marked packs, unbranded neutral\u2011label units and fully customized OEM battery packs. Before each shipment, every battery goes through multi\u2011stage quality inspection including capacity sorting, voltage consistency verification and internal\u2011resistance sampling. This rigorous QC workflow delivers predictable, uniform battery\u2011life performance across your full production batch.<\/div>\n<\/div>\n
