Each battery comes with a USB charging cable. Connect the cable to the JST-XH charge port on the battery and plug the USB end into any 5V USB power source (adapter, power bank, or computer USB port). A full charge takes approximately 90-120 minutes. Avoid using the battery immediately after charging — let it cool for a few minutes before driving.

This 7.4V 2S battery fits most 1/14 and 1/16 scale 4WD RC cars and trucks that use a Deans T plug and 7.4V / 2S power system. Before ordering, please verify:

1. Battery compartment size is at least 70 x 38 x 18mm.
2. Plug type is Deans T.
3. Your car runs on 7.4V (2S), not 11.1V (3S) or 14.8V (4S).

2× PCEONAMP 7.4V 3000mAh 2S Li-ion RC batteries (Deans T plug), 2× USB charging cables, and 1× user manual. Everything you need to get started — no additional charger required.

Yes. This 3000mAh pack provides approximately 36% more capacity than the standard 2000mAh battery found in most RC cars, giving you noticeably longer run time per charge. The physical dimensions (70 x 38 x 18mm) are designed to fit the same battery compartment, so it is a direct swap with no modification needed.

Simply open the battery compartment on your RC car, remove the old battery, and drop this one in. Connect the Deans T plug to your car’s power wire and the JST-XH connector to your charger. That’s it — no wiring, no soldering, no tools required.

No. This is a 2S (7.4V) battery. It is only compatible with 7.4V / 2S RC cars and trucks. Do not use it in 3S (11.1V) or 4S (14.8V) systems, as this may cause damage to your vehicle’s electronics.

Store in a cool, dry place away from direct sunlight. For long-term storage (over 1 month), keep the battery at approximately 50% charge (about 7.4V per cell). Do not leave the battery fully charged or fully drained for extended periods. Keep away from children and pets.

Li-ion (Lithium-ion) and LiPo (Lithium Polymer) batteries are both rechargeable and used in RC vehicles. The main differences are in the materials used and the shape:

• Materials: Li-ion batteries use a different chemical composition, which generally results in a more stable and safer battery.
• Shape and Flexibility: Li-ion batteries are typically rigid and have a fixed shape, while LiPo batteries are more flexible and can be made in various shapes and sizes.
• Charging: Both can be charged using similar methods, but Li-ion batteries are often charged via a fixed voltage (7.4V for 2S), while LiPo batteries may require a balance charger to ensure each cell is charged equally.

The expected lifespan of this 3000mAh 2S Li-ion battery is typically around 300-500 charge cycles, depending on usage and maintenance. Proper care, such as avoiding overcharging and deep discharges, can help extend the battery’s life.

When the battery is no longer usable, it should be disposed of properly. Do not throw it in the regular trash. Instead, take it to a designated battery recycling center or follow local regulations for hazardous waste disposal.
