Changing battery/inside connectors

well surly you should, instead of 4 motors running on 14.4v 2 are instead, there fore more for those wheels wont you?

alistair the thats also an option but it woud probably only be a tempoary thing

Nope. You do not understand the way that power is distributed in a parallel circuit. All four motors should get 14.4v. The overall current demands of the circuit may be higher leading to temporary voltage drops from the battery but nothing else. Theres a reason why others dont do as youre suggesting.

I like to use a mixture of ring crimp connectors with a bolt holding them together (just make sure that the bolt and connectors are insulated) or anderson connectors like the ones that ewan suggested for connections that shouldnt be permanent.

right, thanks ewan for straightening that out,

at the last event my battteries once chargered werent fully charged as i had to put them on again, is there anyway roung this?

thanks alex

also will a 2wd robot on 14.4v be faster than a 4wd? or would they be the same?

i apoligise if some has already hinted at this but just want to be sure:)

alex

Should be the same. If you use 4wd the robot will have more grip and should have more acceleration. And if you use 4 motors it will have more power.

i have in the past few days soldered the speedo wires to the motors, but stupidliy cut off the original red and black wires, and didint know which was pos or neg

any how thanks to some photos oi think i have it right, but will it do anything damage any components if i have got the wrong way around?

alex

I believe so - never done it myself (yet) but I think if you power up the speedos with reverse polarity its certainly not good for them. Not sure of the symptoms, but Im guessing probably the magic smoke :)

what so it will damage the speedos not the motors?

If its the leads from the speed controller to the motors it wont do any damage whatsoever. Your motors will simply rotate in a different direction. Best to test everything loosely (screw terminals or similar) to find out what connection combination gets the motors all going in the right direction (forwards, back, left, right all together when commanded) then solder everything when youve got it right.
