\n
The BAKTH\u201118650\u20114S2P\u20113M lithium-ion battery pack adopts 4S2P configuration with 18650 cylindrical cells, engineered for B2B equipment manufacturers seeking slim-profile, high-energy portable power sources. With 14.4V nominal voltage and 5.2Ah rated capacity delivering 74.88Wh, this pack strikes an ideal balance between compact size and sustained runtime, fitting devices that require long working hours while keeping the internal assembly lightweight and thin.<\/div>\n<\/div>\n
\n
This battery pack features a max charging voltage of 16.8V and 9.6V discharge cut-off voltage, supporting 3A max charge current to accelerate charging cycles for your end products. The integrated BMS continuously monitors voltage, current and temperature of each cell, delivering comprehensive protection against over-charge, over-discharge, over-current and short-circuit risks to lower product failure rates and enhance end-user safety. It maintains consistent output under extreme ambient temperatures ranging from -20\u2103 up to 60\u2103, suitable for both indoor factory use and field mobile operation.<\/div>\n<\/div>\n
\n
All units pass rigorous third-party safety and compliance audits. Complete certification documents including IEC62133 safety report, UN38.3 transportation test file and RoHS compliance certificate can be provided with bulk shipments. These official documents simplify overseas customs clearance and product certification for your finished devices sold into EU, North American and global industrial markets.<\/div>\n<\/div>\n
\n
Ultra-slim form factor is one of the core advantages. The pack\u2019s maximum dimension is 150mm \u00d772mm \u00d720mm and net weight only 400g. Its flat thin housing is perfectly suited for space-constrained device enclosures, eliminating the need for large structural modifications to your existing product shell. Customization options include wire length adjustment, connector replacement and private label printing.<\/div>\n<\/div>\n
\n
We support flexible bulk procurement with three branding options: standard BAKTH branded packs, blank neutral unmarked batteries, and full OEM custom labeling with your corporate logo. Every battery is subject to multi-stage QC workflows before delivery: cell matching, internal resistance screening, voltage balancing and sample cycle testing. This strict quality control ensures batch consistency for your mass production.<\/div>\n<\/div>\n
