The ASOL505060 is a premium Li-ion rechargeable battery pack using two flat 505060 soft-pouch cells in a 2S1P series configuration, delivering a stable 7.4V nominal voltage and 2000mAh capacity (14.8Wh). Each 505060 cell is approximately 5 × 50 × 60 mm (T × W × L). The two cells are stacked vertically, producing a finished pack approximately 10 × 50 × 62–63 mm (T × W × L), including the assembly allowance for the protection board, wiring and insulation.
7.4V is the standard operating voltage for many small-to-medium RC vehicles, FPV micro drones and robotic toys. With 2000mAh capacity, the ASOL505060 provides a balanced combination of runtime and pack weight for RC cars, RC trucks, FPV racing drones, nano quadcopters, RC boats, STEM educational robots and programmable smart toys. The flat Li-ion cell construction also allows for flexible placement within device housings: the slim profile can fit under circuit boards, inside narrow battery compartments or flush against device walls where cylindrical batteries cannot be accommodated.
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. Inspection requirements and acceptance criteria are confirmed for each project before order release.

Frequently Asked Questions
Is the ASOL505060 compatible with RC cars, FPV drones, and robot toys?
Compatibility should be confirmed against the target RC, FPV or other 7.4V system requirements, including operating current, peak current, connector, polarity, dimensions and charging requirements.
What is the minimum order quantity (MOQ)?
MOQ is confirmed after specification review. Sample evaluation may be available for selected cylindrical and lithium polymer battery projects, subject to specification review and product availability. Sample freight is paid by the customer.
Can I use this battery for my FPV drone or micro quadcopter?
Yes. The 7.4V 2S Li-ion format is widely used in FPV micro drones, nano quadcopters, and tiny whoop racing drones. The flat 505060 Li-ion cell format provides a compact, lightweight power solution that integrates well into small drone frames.
What connector options are available?
We support all standard RC and consumer electronics connectors: JST-PH 2.0, JST-XH, Tamiya, Deans T-plug, XT30, XT60, Molex, and custom connectors. Balance charge connectors (JST-XH 3-pin) can be included for 2S balance charging.
What certifications does the ASOL505060 have?
The finished ASOL505060-2S 7.4V 2000mAh battery pack has China CCC / 3C certification to GB 31241-2022. Other certification and test-document requirements depend on the selected configuration and destination market; please confirm requirements during project review.
What is a 505060 Li-ion cell?
505060 refers to the single cell's nominal dimensions: approximately 5mm thick × 50mm wide × 60mm long (T × W × L). The finished 2S1P pack is larger, at approximately 10 × 50 × 62–63 mm (T × W × L).
How does 505060-2S Li-ion compare with 18650-2S for RC applications?
The 505060-2S Li-ion is 60%+ thinner and 10%+ lighter than an equivalent 18650-2S pack, making it ideal for compact RC chassis and small drone frames. Li-ion cells also have lower internal resistance for less voltage sag under acceleration. 18650-2S offers higher total capacity for longer runtime but in a larger, heavier form factor. Choose 505060-2S when space and weight are critical; choose 18650-2S when maximum runtime is the priority.
