\n
BAKTH-21700CD-53E-4S3P adopts premium 21700 cells with 4S3P layout, engineered for B2B integrators seeking high energy density, high charge current lithium power source for medium-load mobile equipment. This battery pack delivers 14.4V nominal voltage, 15.9Ah rated capacity and total energy of 228.96Wh, supporting faster charging with max charge current of 15.9A. Its electrical specifications: max charging voltage 16.8V, discharge cut-off voltage 7.5V, built-in BMS safeguards against overcharging, over-discharging, overcurrent and short-circuit faults to secure your finished devices.<\/div>\n<\/div>\n
\n
Different from 18650 battery packs, this 21700 cell solution brings higher single-cell capacity while maintaining compact footprint. The hard plastic outer shell offers stronger shock resistance, suitable for equipment that faces vibration during movement and field transportation. Dimension limited within 87mm \u00d771mm \u00d773mm and total weight 865g, it balances power density and installation space, convenient for product structural design and assembly. The operating discharge temperature covers -20\u2103 ~ 60\u2103, performing steadily in temperate cold environments and indoor industrial workshop conditions.<\/div>\n<\/div>\n
\n
All packs pass strict quality screening before delivery, with full certification documents IEC62133 safety certificate, UN38.3 lithium battery transport report and RoHS compliance file, convenient for cross-border shipment, customs clearance and product certification for EU and North American markets.<\/div>\n<\/div>\n
\n
We provide flexible OEM & ODM custom service for bulk buyers. Options include customized cable length, DC connector types, private label printing and neutral unbranded packaging. Every battery pack goes through internal resistance sorting, voltage matching and aging cycle testing, ensuring consistent batch performance and reducing failure rate during mass assembly.<\/div>\n<\/div>\n
