RX pack voltage

[dhutch]

Atm in my nitro i have a 5cell (6v) RC pack, but i was wondering, why

- why dont we use 6cell, 7.2v packs, like in electrics

[BCSavage]

cuz most rx's can't handle more than 6.0 volts

[dhutch]

but, thats what they run on in all my electric cars

- an BEC Rx should be able to handle 7.2v surely?

[BCSavage]

I thought an ESC stepped the voltage down to 6? could be wrong.

[dhutch]

some might, but i know that both of mine dont (you can see the tracks on the PCB leading stright from the battery to the Rx lead)

i was under the impresion that the new BEC (battery eliminator circuitry) RX's where designed to take upto 7.2v - and looking at the tracks on the Rx PCB all the pwoer terminals are comoned together

- so i know that the servos on some of my cars have 7.2v across them, so i think it should be fine. (i think)

i was just trying to see if anyone else used 7.2v RX packs

[BCSavage]

Hmmm, well I just read the specs on my Novak Explorer II and it says it's BEC circutry puts out 5.0 volts.

[dhutch]

well, im not saying your wrong, infact im intersested to know, but my old Novak ECS (not sure of the model as it was 2nd hand) defonatly gives out the full 7.2

- ah well, i'll get 6 Ni-mh AA cells and try it out :P

- might swap out my High torgue servo first tho :D

I never accused you of saying I was wrong :p I just thought I'd post as much info as I could find. Nothing worse that an intelligent debate without some good solid facts :D

[dhutch]

yeah, fine :D

- i was just making sure :p

[BCSavage]

good, as long as were on the same page ;)

on a side note, 5.0V seems awfully low.

becs are now located in the esc's 99% of the time and they put out 5-6v. bad bec's/esc's claim 5v but may only put out 4.5 or so v's (like the novak evx in the emaxx, i have one) and others like my 7.1 and old C2 put out 5-6v (havnt acctually measured it) i put an 6v RX pack in my emaxx and it really helped steering response.

also recievers now can usualy handal 5-7v easily and some can handall a 9v alkaline. usualy when using higher voltage bec's the rx can take it but servos burn out. so when you use a 6cell rx pack make sure your servo has been known to survive or your using a servo you dont care about. tho its just a little simpler to use a 5c rx pack and avoid any problems :D
