Designed specifically for the E-flite micro series. A direct replacement for the E-flite 2S 200mah lipoly battery - E-flite part #: EFLB2002S25.

More punch, more power and longer flight times are only the beginning. When tested with the E-flite micros, the differences between a regular pack and the nano-tech where remarkable! Power output and flight time were greatly improved due to the higher discharge rate and true capacity.

Bring your E-flite micro to life with the nano-tech upgrade cells!

Capacity: 300mAh
Voltage: 2S1P / 2 Cell / 7.4V
Discharge: 35C Constant / 70C Burst
Weight: 16g (including wire, plug & case)
Dimensions: 44x18x12mm
Discharge Plug: E-Flight Ultra Micro

Suited to the following models: E-flite micros utilizing EFLB2002S25 battery

* The nano-core technology in lithium ion batteries is the application of nanometer conductive additives.
1) The nanometer conductive additives form ultrastrong electron-conducting networks in the electrodes which can increase electronic conductivity.
2) These additives create a superstrong ability for imbibition in the carrier liquid to supply more ion channels. This improves the ability of ion transmission and ion diffusion.
Through improving electronic conductivity and ion transmission, the impedance is reduced and the polarization of high rate discharge decreases greatly.
Advantages over traditional Lipo batteries;
-Power density reaches 7.5 kw/kg.
-Less Voltage sag during high rate discharge, giving more power under load.
-Internal impedance can reach as low as 1.2mΩ compared to that of 3mΩ of a standard Lipoly.
-Greater thermal control, pack usually doesnt exceed 60degC
-Thickness swelling during heavy load doesnt exceed 5%, compared to 15% of a normal Lipoly during heavy load.
-Higher capacity during heavy discharge. More than 90% at 100% C rate.
-Fast charge capable, up to 15C on some batteries.
-Longer Cycle Life, almost double that of standard lipoly technology.

Best battery for umx micros

Feb 27, 2020

This is the best 2s battery I have found so far for the umx micros. It fits everything, even the belly-slot on the p51 and p47 (the old 260s from hobbyking were too fat!). It makes the p47 fly like the p51 even though it has a weaker motor and it powers the 3600kv geebee motor very well!

Works perfect for UMX Timber

Feb 12, 2020

This battery has good punch and flights could go far past my 5 minute timer. Connector worked perfectly with stock E-Flite connector on my UMX Timber. CG was fine with it all the way forward on the velcro.

Great UMX Timber batteries!

Feb 10, 2020

Got a hand full of these for my little UMX eflite Timber. Work perfectly. Cruising around 7 minutes of flight time. Very nice. Don't try to charge at a high rate and they last forever. 1c charge is just fine. Get half a dozen packs and at 1c you can fly and have them on the charger cycling through for pretty much steady flying all day.
