Lithium Polymer cells


 Lithium-Polymer cells = 
maximum energy density at minimum weight
Example: Fullriver 130 - the energygnome with only 3.6g!

Fastcharging within 1 hour with 1 * C
High Discharge Current cont. & pulse
self discharge rate (5%/ year)
flat discharge curve, no Memory Effect

we ship these batteries as packs of one (3.7V), two (7.4V) 
or three cells (11.1V) with a bare PCB for easy soldering 
of your connector leads.


1-, 2- and 3-cell powerpacks Kok145,Kok350H, Kok640H, Kok1200H, Kok1500H and Kok3270


Our series Little Bee weighs just 56g
and flies more than 15 minutes with a
2-cell pack Fullriver 130 cells without recharging!

 

Nominal Voltage/ cell = 3,7 V.  Recharge voltage = 4.2+/-0.05V/ cell.

Note: For recharging you either need our Automatic Li-charger or a laboratory power supply with controlable current and voltage!
Do not use normal NiCd charger !!!
 For proper operation of a coreless motor from a voltage source with a nominal voltage of 9.5V and more (= 3 Lipo cells) you need to control the rpm with a high frequency
controller like the HF100kHz controller. Otherwise the life expectancy of your motor will be significantly reduced because of high current spikes especially at part throttle.
