\n
Built for integrators searching for long\u2011duration, sustained\u2011power backup solutions, the BAKTH\u201118650\u20113S15P\u20115 is a 3\u2011series, 15\u2011parallel 18650 lithium\u2011ion battery pack delivering 10.8V nominal voltage, massive 39\u2011amp\u2011hour capacity and 421.2Wh energy storage. Its distinctive elongated rectangular layout is engineered specifically for equipment with narrow, extended battery cavities, freeing designers from square\u2011shaped battery\u2011space limitations.<\/div>\n<\/div>\n
\n
Every unit is manufactured to international industrial standards, backed by three core compliance credentials: IEC62133 cell\u2011safety certification, UN38.3 lithium\u2011battery shipping approval, and RoHS hazardous\u2011substance compliance. These documents remove major barriers when your finished machinery is imported into European, North\u2011American and other overseas territories, shortening customs lead\u2011time and lowering audit\u2011related risks. Reliable discharge performance is maintained across the wide\u2011ranging\u201120\u2103\u201160\u2103 temperature spectrum, capable of continuous power supply both for indoor standby devices and field\u2011deployed heavy\u2011load hardware.<\/div>\n<\/div>\n
\n
An upgraded internal battery management system provides comprehensive protection against over\u2011charge, over\u2011discharge, over\u2011current, short\u2011circuit and thermal overload. This high\u2011capacity pack supports a maximum charging current of 10A for fast\u2011charging workflows, with full\u2011charge voltage set at 12.6V and low\u2011voltage cut\u2011off threshold of 8.4V. Bare red\u2011and\u2011black lead\u2011wires leave full flexibility for buyers to terminate with their preferred connector type on\u2011site, greatly simplifying connector\u2011matching work for custom\u2011built machinery.<\/div>\n<\/div>\n
\n
The long\u2011shaped pack has maximum outer dimensions of 295mm(L) \u00d7 61mm(W) \u00d7 68mm(H), with a total weight of 2300g. Thanks to its 39Ah large\u2011capacity configuration, the battery delivers extremely long running\u2011time between charges, effectively reducing the frequency of recharge cycles and lowering long\u2011term maintenance costs for your end\u2011users.<\/div>\n<\/div>\n
\n
We offer multi\u2011level commercial cooperation for volume industrial clients and long\u2011term framework supply contracts. Available options include original BAKTH branded packs, blank neutral\u2011label units, and in\u2011depth OEM modifications: custom connector assembly, wire\u2011length adjustment, printed outer\u2011shell labels and fine\u2011tuning on charge\u2011discharge parameters. Every high\u2011capacity battery pack goes through multi\u2011stage aging and load\u2011testing procedures before delivery, ensuring well\u2011balanced cell groups and stable long\u2011cycle performance in heavy\u2011load continuous\u2011operation scenarios.<\/div>\n<\/div>\n
