\n
Engineered for space\u2011critical miniature industrial hardware, the BAKTH\u201118650\u20116S1P\u20112 is an ultra\u2011compact 6S1P 18650 lithium\u2011ion battery unit with 21.6V nominal voltage, 2.6Ah capacity and 56.16Wh energy density. It is purpose\u2011built for compact machinery where available internal installation room is extremely limited.<\/div>\n<\/div>\n
\n
This battery pack holds complete IEC62133 safety certification, UN38.3 transport qualification and RoHS environmental compliance, removing certification obstacles when you export finished machines to European and North\u2011American markets. It maintains steady power delivery across\u201120\u2103 to 60\u2103 discharging scope, coping with cold field deployment as well as heat\u2011prone enclosed device cavities.<\/div>\n<\/div>\n
\n
Equipped with integrated BMS circuitry, the module delivers multi\u2011fold safeguards covering over\u2011charge, over\u2011discharge, over\u2011current and short\u2011circuit hazards. It adopts 0.5C standard charging specification, max charging voltage 25.2V and discharge cut\u2011off voltage 16.8V, effectively mitigating cell degradation during repeated cyclic work and extending overall service lifespan.<\/div>\n<\/div>\n
\n
Boasting tiny outer dimensions of max 55mm(L) \u00d7 50mm(W) \u00d770mm(H), the battery weighs merely 300g. Its mini cylindrical\u2011style layout saves valuable internal device space, perfect for compact handheld instruments, miniature automation modules and portable lightweight gadgets.<\/div>\n<\/div>\n
\n
We deliver flexible B\u2011end branding alternatives for bulk and project orders: original BAKTH logo, unbranded neutral units and fully customized OEM labelling are all accessible. Every single batch goes through strict factory performance validation, ensuring uniform output consistency for your end\u2011product assembly lines.<\/div>\n<\/div>\n
