Product overview

VTC18650-7S3P 25.2V 9000mAh Lithium-Ion Battery Pack for E-bike controllers, portable power modules, industrial backup devices | Battery Manufacturers in China & Battery Supply Factory

The VTC18650-7S3P is a lithium-ion battery pack built in a 7S3P cylindrical assembly with 25.2V nominal voltage, 9000mAh nominal capacity, 8700mAh minimum capacity, 29.4V limited charge voltage, and 17.5V discharge cut-off voltage. This pack supports 0.2C standard charge and discharge at 1800mA, rapid charge up to 0.5C, and maximum discharge up to 0.5C, while the finished pack size is controlled within 56 x 73 x 129mm and the weight is about 1.2kg. The datasheet also defines overcharge, overdischarge, overcurrent, and short-circuit protection parameters, making it suitable for OEM equipment integration where stable electrical management is required.

VTCBATT provides factory supply, custom lithium battery pack development, connector and wire matching, sample support, OEM/ODM production, and battery wholesale service for customers that need repeatable batch delivery.

01

Application Ready Connectors

The outline drawing shows a DC5521 charge connector, separate P+ and P- discharge terminals, 150+/-5mm wire length, and 18AWG charge and discharge leads, which gives integrators a clearer starting point for enclosure layout and harness matching. VTCBATT can use this pack structure for connector adaptation, lead customization, and application-specific output configuration in sample or batch supply.

02

High Energy 25.2V Pack

The VTC18650-7S3P combines a 7S3P cylindrical cell structure with 25.2V nominal output and 9000mAh nominal capacity, giving OEM equipment builders a compact rechargeable pack for portable power modules and controlled DC systems. With a maximum pack size of 56 x 73 x 129mm and 226.8Wh nominal energy shown on the outline drawing, it fits projects that need meaningful runtime without a bulky enclosure.

03

Protected 7S3P Assembly

This battery pack is supplied with defined protection thresholds in the datasheet, including overcharge detection at 4.250+/-0.025V per cell, overdischarge detection at 2.50+/-0.080V per cell, and overcurrent detection at 15+/-3A. That makes it better suited to OEM assemblies that require a documented protection structure instead of an unspecified replacement battery block.

04

Stable Batch Supply

For B2B buyers, this model is not just a single pack concept but a documented assembly with named dimensions, protection parameters, test conditions, and temperature-dependent operating limits. VTCBATT can position the pack for OEM projects that need sample evaluation first and then repeatable factory-direct production for replacement programs, integrated devices, or distributor orders.
