\n
Engineered for space\u2011constrained device designs, the BAKTH\u201116340\u20111S\u20113 is a tiny single\u2011cell cylindrical lithium\u2011ion battery pack built to deliver consistent low\u2011current power for compact electronics. Boasting nominal specifications of 3.7V, 680mAh and 2.52Wh, this slim battery module is the perfect power upgrade option for product developers aiming to shrink their device shell size while retaining dependable rechargeable performance.<\/div>\n<\/div>\n
\n
Equipped with an integrated battery management circuit, this battery pack delivers comprehensive safeguards against over\u2011charge, over\u2011discharge and short\u2011circuit risks. Its electrical parameters have been fine\u2011tuned for safe, stress\u2011free daily operation: a maximum charging voltage of 4.2\u202fV, 3.0\u202fV discharge cut\u2011off threshold and a standard 1C maximum charge\u2011current rating. Thanks to its wide\u2011range discharge temperature tolerance of\u201120\u202f\u00b0C to 60\u202f\u00b0C, the battery can reliably run equipment deployed both indoors and moderately\u2011exposed outdoor environments without performance drop\u2011off.<\/div>\n<\/div>\n
\n
Every production batch is tested and approved to meet global lithium\u2011ion safety and shipping standards: IEC62133 cell\u2011safety certification, UN38.3 transportation approval and RoHS hazardous\u2011material compliance. The complete certification package eliminates complex customs\u2011clearance hurdles, making cross\u2011border wholesale shipments straightforward for component distributors, electronics manufacturers and IoT solution providers.<\/div>\n<\/div>\n
\n
Measuring maximum 37.5\u202fmm \u00d7 17\u202fmm \u00d7 17\u202fmm and weighing merely 20\u202fg, this ultra\u2011light cylindrical pack occupies minimal internal enclosure space. It comes pre\u2011fitted with multi\u2011strand lead wires and a compact white plug\u2011in connector right out of production. Our engineering team offers custom modification services, allowing you to adjust cable length, swap connector styles or re\u2011arrange pin assignments, which helps you achieve plug\u2011and\u2011play compatibility without costly hardware redesigns for your finished\u2011goods.<\/div>\n<\/div>\n
\n
We deliver scalable bulk\u2011order services oriented toward long\u2011term industrial\u2011buyer partnerships. Three branding options are available: original BAKTH branded batteries, unmarked neutral packs and fully\u2011custom OEM solutions including custom printed labels. Every finished battery undergoes capacity grading, voltage consistency inspection and cycle\u2011life sampling testing before dispatch, to guarantee uniform quality and predictable long\u2011term runtime across your large\u2011volume projects.<\/div>\n<\/div>\n
