Oper8 11.1V Li-ion 2500MAH Stick Battery

Stick-type battery spaces usually mean small capacity. Not with this one: the Oper8 11.1v Li-Ion stick fits three round cells in a line and holds 2500mAh, so your AK, MP5K or UMP can run at 11.1v all day.

It measures 198mm long and 18.7mm across, much like a NiMH stick. That suits AK variants where the battery sits under the top cover, as well as the MP5K and UMP. It can also go in the stock tube of an M4 or AR-style AEG, but because it's long, the stock may not collapse all the way.

If you need something shorter for a stock tube, the 11.1v 1500mAh LiPo stick is only 120mm long. Charge this pack on a LiPo balance charger set to 3S, such as the ToolkitRC UN3 balance charger.

Why Li-Ion?

• Three high-grade cells with a 20C continuous rating
• No need to run it flat first, thanks to no memory effect
• Very slow self-discharge, so a charged pack stays ready
• No swelling from age, unlike a neglected LiPo

Before you fit an 11.1v pack: make sure your gun is set up for it. A gearbox, motor or trigger contacts that aren't built for 11.1v can be damaged, so we can't accept responsibility for damage caused by using one in an unsuitable gun. A MOSFET is strongly recommended.
