The ASOL333047-2S is a premium Li-Polymer (LiPo) battery pack using two flat 333047 soft cells in 2S1P series configuration, delivering a stable 7.4V nominal voltage and 500mAh capacity (3.7Wh). The 333047 LiPo cell format (3.3mm thick × 30mm wide × 47mm long) is one of the smallest standard soft-cell sizes available, enabling an ultra-compact and featherweight pack design at just ~25g — making it the go-to choice for micro aerial vehicles, mini RC toys, and tiny robotic devices where every gram matters.
7.4V (2S LiPo) is the standard operating voltage for the majority of micro and mini RC vehicles, toy-grade drones, and small electronic devices. With 500mAh capacity and 1C-2C discharge rate, the ASOL333047-2S delivers reliable power for micro FPV drones, nano quadcopters, mini RC cars, micro RC boats, and small educational robots. The incredibly thin 3.3mm cell profile allows flexible mounting in the tightest device enclosures — behind PCBs, under chassis plates, or inside hollow frame arms of micro drones — where no other battery format can fit.
Each pack incorporates a built-in PCB protection circuit (or optional full BMS with 2S cell balancing) guarding against overcharge, over-discharge, overcurrent, and short circuit. Every unit is manufactured at our quality-controlled facility and passes 100% outgoing QC: open-circuit voltage verification, capacity discharge testing, and protection circuit function check before shipment. Grade-A LiPo cells are voltage-matched within ±10mV to ensure stable series operation and uniform cycle aging.

What certifications does the ASOL333047-2S have?
All standard packs ship with CE, RoHS, UN38.3, MSDS compliance.
What is a 333047 Li-Polymer cell?
333047 refers to the cell's physical dimensions: 3.3mm thick × 30mm wide × 47mm long. This is one of the smallest standard soft-cell LiPo formats, designed for ultra-compact devices like micro drones, mini RC toys, and tiny robots where space is extremely limited.
How does 333047-2S compare with larger LiPo or 18650 packs?
The 333047-2S is the smallest and lightest option: ~25g vs ~60g (103450-2S) vs ~90g (18650-2S). Its 3.3mm thickness makes it uniquely suited for micro RC and nano drone applications. 103450-2S offers higher capacity (2000mAh) for medium RC vehicles and toys. 18650-2S provides the highest energy density (2600-3500mAh) for larger devices.
