Application
1/6 and 1/7 scale RC cars, trucks, buggies, truggies, and short course trucks. Also suitable for high-power robotics, drone ground stations, and other demanding DC applications that require a compact 4S 14.8V pack with high current output.

Please Notice
Always charge with a proper LiPo balance charger set to 4S (14.8V) and never exceed 4.2V per cell. Do not discharge below 3.2V per cell. Store at 3.8V–3.85V per cell for long life. Use only with XT90 compatible devices or adapters rated for 90A+ continuous. Avoid puncturing, overcharging, or exposing to high temperatures. Inspect for swelling before each use. Keep away from children.

FAQ
Q1: Can this battery be used in my 1/7 scale RC truck with a different plug?
A: The battery comes with XT90 discharge plug. If your ESC uses a different connector (e.g., EC5, Deans/T-plug, or TRX), you need an adapter or must solder a compatible plug. 

Q2: What charger do I need for this 4S 6500mAh LiPo?
A: You need a balance charger capable of charging 4S LiPo batteries (14.8V) with at least a 6.5A charge current (1C) for a full charge in about one hour. The charger must have a JST-XH balance port (compatible with JST-XHR-5P). Always set the correct cell count.

Q3: How long will the battery last on a single charge?
A: Runtime depends on your vehicle and driving style. With 6500mAh capacity, expect roughly 20–40 minutes of aggressive off-road driving or 30–50 minutes of casual running on a typical 1/8 scale buggy. Higher current draw (e.g., large wheels, heavy throttle) reduces runtime.

Q4: Is the hard case removable? Can I use it in a drone?
A: The hard case is not designed to be removed. It adds protection for car/truck applications but increases weight and size. For drones, a soft-case LiPo is usually lighter. However, if your drone has a large battery bay (approx. 139×47×49mm), you can use it but expect reduced flight performance due to higher weight.
