Installation Notes
generally do not survive such a high number of charge 
/ discharge cycles as is claimed for other batteries, 
such as Nanophosphate® types. The comparatively 
high nominal voltage of 7.4 Volt of a two-cell LiPo pack 
presents no problems to Graupner HoTT receivers, nor 
to those servos, speed controllers, gyros, etc. which are 
expressly approved for use at these higher voltages. 
Please note, however, that virtually all servos, speed 
controllers, gyros etc. sold in the past, and also 
most of those currently available, are only approved 
for use on an operating voltage in the range 4.8 to 6 
Volt.
 If you wish to connect these devices to the recei-
ver, it is essential to use a stabilised regulated power 
supply, such as the PRX, Order No. 4136; see Appendix. 
If you neglect this, there is a danger that the connected 
devices will quickly suffer permanent damage.
