High Burst and Reactivity:
The Ultra Power line by Evolution is designed to deliver a clean and constant current flow to the motors of airsoft replicas. This 2-cell Li-Po (7.4V) delivers a continuous discharge of 20C with peaks up to 40C: this translates into a smooth firing cycle, excellent burst, and, above all, an immediate and snappy trigger response, without straining the mechanical components of the Gearbox.
"Double" Format (Crane/Nunchuck):
Dimensions matter when it comes to battery compartments. This Li-Po is divided into two separate modules, each measuring 6.1 x 21 x 130 mm. This split configuration is the choice of election to be housed in the stock tubes of M4 platforms, in Crane-type stocks or inside thin handguards, optimizing space without sacrificing amperage (a good 1300mAh, enough to easily cover a standard Sunday game).
Maximum Versatility (T-Deans + Adapter):
One of the absolute strengths of this product is connectivity. The battery is factory wired with a T-Plug (Deans) connector, the best in airsoft because it drastically reduces electrical resistance and avoids overheating. However, for those who own replicas with standard wiring, Evolution includes a practical T-Deans to Mini-Tamiya adapter in the package. You can use it on any rifle from the first moment, without having to solder or cut wires!
The advantage of T-Deans: Even if the Mini-Tamiya adapter is very convenient, remember that each adapter creates a slight "bottleneck" in the current flow. If your replica has the Mini-Tamiya, use it without problems; but the Pro Tip is to have the connector of your rifle changed by putting a nice direct T-Deans. You will completely eliminate the adapter, gaining additional space in the stock tube and increasing the electrical efficiency of the rifle!
Charging and Safety (The golden rules of Li-Po): Lithium Polymer batteries are very powerful but delicate. Only use balanced battery chargers specifically for Li-Po (always connecting the small white cable). NEVER discharge the battery to zero: if you feel that the rifle slows down the rate of fire, stop immediately and disconnect the battery, or you risk swelling it and making it unusable. Finally, always store and charge your Li-Pos inside the appropriate fireproof Lipo Safe Bag (you can find them in our catalog!).
