Import 36v 12ah Li Ion Electric Bike Battery With Usb — Buy in wholesale FOB from Supplier in China

The Unit Pack Power 36V 12AH lithium-ion electric bike battery is a down-tube format pack built around 18650 cylindrical cells, delivering 432 Wh nominal energy with a 20 Amp continuous BMS and 50 ± 10 Amp peak discharge. Its physical envelope measures 108 by 340 mm and the unit weighs 4.1 kg, making it a direct replacement for standard frame-mounted installations on 36 V systems rated from 250 W to 500 W motor power. The pack carries a USB auxiliary output and is certified to CE, RoHS, UL, MSDS and UN38.3 standards.

Cell chemistry is lithium-ion with a cycle-life rating of 80 % retained capacity after 800 full cycles, which is typical for 18650 NMC or LMO cell constructions in the 2,000-2,500 mAh per cell range. The 20 A continuous BMS protects against over-current, over-discharge and cell imbalance, while the 42 V 2 A or 3 A charger brings the 10 S pack from flat to full in roughly 4-6 hours. Standard 18650 form factor means the pack can be serviced with widely available replacement cells, a practical consideration for fleet operators.

This battery suits OEM electric bike manufacturers, conversion-kit distributors and fleet-rental operators who need a tested, certificated power source for 36 V mid-drive or hub-motor systems. The USB port supports phone charging or lighting accessories, a feature increasingly requested by commuter and delivery segments. Buyers should confirm exact cell brand, BMS firmware version and connector type (Anderson, XT60 or barrel) with Unit Pack Power before finalising an order, as these details affect compatibility with existing controller harnesses.

Unit Pack Power is based at No.196 Tangtou Street, Shiyan Town, Shenzhen, Guangdong Province, 518109, placing its manufacturing and engineering operations in one of China's principal lithium battery production clusters. The supplier holds a harbor trust tier on the platform, though its response rate is recorded at 0.00 % with zero average response hours, indicating that direct communication may be slow or that the account is not actively monitored through platform messaging.

The company lists model UPP-S002-2+USB for this 12 Ah variant, suggesting a standardised platform approach across multiple capacity configurations. No factory size, year of establishment, revenue figures or named client list appears in the available profile. Buyers should treat the address as the primary contact point and verify factory audit status, ISO 9001 quality system registration and actual production capacity through direct due diligence rather than platform signals alone.
