\n
Engineered for projects that demand dependable 12.8\u2011volt power output and extended service lifespan, the BAKTH\u201126650FE\u20114S1P\u20112 battery pack adopts a 4\u2011series, 1\u2011parallel internal configuration built from durable 26650\u2011size lithium\u2011iron phosphate cells. Delivering a nominal capacity of 3.3Ah and total stored energy of 42.24Wh, this power module stands out as a long\u2011term energy source ideal for equipment that requires frequent deep charge\u2011discharge cycles.<\/div>\n<\/div>\n
\n
Its charging workflow follows a conservative, safety\u2011first 0.5C charge\u2011rate limitation, paired with a maximum charging voltage of 14.6V and a 10V hard cut\u2011off threshold to safeguard cell health over thousands of repeated cycles. The on\u2011board battery management system delivers multi\u2011directional protection, preventing damage caused by over\u2011charging, deep over\u2011discharge, excessive current draw and accidental short\u2011circuit faults. Thanks to its wide\u2011range thermal performance from\u201120\u2103 to 60\u2103, the pack maintains steady energy output even when installed inside poorly\u2011ventilated cabinets or deployed to outdoor sites experiencing sharp temperature swings.<\/div>\n<\/div>\n
\n
Every production batch completes third\u2011party compliance testing, providing full\u2011set certification documents: IEC62133 cell\u2011safety verification, UN38.3 transportation approval and RoHS hazardous\u2011substance compliance. This complete certification portfolio removes shipping obstacles for international distributors and OEM integrators, streamlining cross\u2011border logistics and local market regulatory acceptance.<\/div>\n<\/div>\n
\n
Housed within a tough blue wrapped outer shell, the finished battery reaches maximum outer dimensions of 108mm \u00d7 70mm \u00d7 27mm, with a lightweight total weight of just 360g. The pre\u2011installed JST\u2011style plug\u2011and\u2011play connector enables quick mechanical installation inside your device housing. Our factory engineering team offers full modification services, including wire\u2011length adjustment, connector replacement, pin\u2011layout modification and custom printed outer labels, helping you achieve perfect hardware matching without costly equipment redesign work.<\/div>\n<\/div>\n
\n
We supply stable, long\u2011term bulk\u2011order cooperation programs for global industrial B2B purchasers. Three branding options are available: original BAKTH\u2011branded units, logo\u2011free neutral\u2011label battery packs, and fully custom OEM assemblies printed with your corporate branding. Every finished battery undergoes multi\u2011stage quality\u2011control inspection before shipment, covering capacity grading, voltage balance checking, internal\u2011resistance consistency testing, plus cycle\u2011life sample validation. This rigorous QC workflow ensures excellent cell\u2011to\u2011cell uniformity for your mass\u2011produced finished products.<\/div>\n<\/div>\n
