Absima LiPo Battery Pack 22.2V 4500mAh 6S 40C Softcase EC5 (4140027)

RC enthusiasts running high-performance models—whether a 1/8 scale buggy on a dirt track, a speed boat cutting across a lake, or a large-scale airplane climbing after takeoff—need a battery that delivers consistent power without adding unnecessary weight. The Absima 4140027 LiPo pack answers that call with a 22.2V nominal output and 4500mAh capacity, built in a softcase format to keep mass low while still protecting the cells. Its EC5 main connector handles high current flow securely, and the JST-XH balancer tap makes maintenance straightforward.

Why choose it

The 40C continuous rating means this pack can supply up to 180 amps without sagging, so your motor gets the punch it needs for hard acceleration and steep climbs. The softcase design trims weight compared to hardcase alternatives, which is critical in models where every gram affects handling. EC5 connectors are known for their low resistance and secure fit, reducing the risk of power loss or accidental disconnection during rough landings or high-vibration runs. With a 99.9 Wh energy content, it sits just under the 100 Wh threshold that often triggers stricter shipping regulations, making it easier to order and transport.

Ideal use cases

• 1/8 scale RC buggies and truggies for racing or bashing
• RC boats requiring high current for planing and speed runs
• Large-scale RC airplanes and EDF jets needing reliable 6S power
• Multi-rotor drones designed for 6S LiPo operation
• Any hobby-grade RC vehicle with an EC5-equipped ESC rated for 22.2V

Good to know

Always use a LiPo-compatible balance charger and monitor cells during charging. Store the pack at approximately 3.8 V per cell when not in use for extended periods. The softcase is not waterproof, so avoid exposure to moisture and protect the pack from punctures. Check that your speed controller's low-voltage cutoff is set correctly for a 6S pack to prevent over-discharge. Absima recommends charging at 1C for maximum cycle life; 2C charging is possible but may reduce longevity.
