The ASOL505060 is a premium Li-ion rechargeable battery pack using two flat 505060 Soft Pouch Cells in 2S1P series configuration, delivering a stable 7.4V nominal voltage and 2000mAh capacity (14.8Wh). The 505060 Li-ion cell format (50mm wide × 50mm long × 6.0mm thick) enables a compact and lightweight pack design — significantly thinner and more space-efficient than equivalent cylindrical cell packs — making it the preferred choice for portable RC vehicles, micro drones, and robotic toys where internal space is limited.
7.4V is the standard operating voltage for the vast majority of small-to-medium RC vehicles, FPV micro drones, and robotic toys. With 2000mAh capacity, the ASOL505060 provides a well-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. Every unit is manufactured at our ISO-certified facility and passes 100% outgoing QC: open-circuit voltage verification, capacity discharge testing, and protection circuit function check before shipment. Grade-A Li-ion cells are voltage-matched within ±10mV to ensure stable series operation and uniform cycle aging.

Frequently Asked Questions
Q: Is the ASOL505060 compatible with RC cars, FPV drones, and robot toys?
A: The ASOL505060 outputs standard 7.4V (2S Li-ion) which is compatible with most 7.4V RC car ESCs, FPV micro drone flight controllers, and robot toy motor drivers. Connector compatibility depends on your device model — we can supply JST, Tamiya, Deans T-plug, XT60, or any other connector to match your wiring harness.
Q: What is the minimum order quantity (MOQ)?
A: Standard configurations start at 50 pcs. For fully custom designs, MOQ is 100–500 pcs depending on complexity. Sample orders of 1–10 pcs are welcome for evaluation.
Q: Can I use this battery for my FPV drone or micro quadcopter?
A: 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.
Q: What connector options are available?
A: 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.
Q: What certifications does the ASOL505060 have?
A: All standard packs ship with CE, RoHS, UN38.3, and MSDS compliance. Additional certifications (UL, IEC 62133) can be arranged for volume orders upon request.
Q: What is a 505060 Li-ion cell?
A: 505060 refers to the cell’s physical dimensions: 50mm wide × 50mm long × 6.0mm thick. This is a standard Soft Pouch Cell Li-ion format that enables flat, compact battery pack designs — ideal for RC vehicle chassis, drone frames, and toy housings where cylindrical cells are too bulky or heavy.
Q: How does 505060-2S Li-ion compare with 18650-2S for RC applications?
A: 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.
