This is a bit basic but I need to get some wire for my tug. Twin CEM 900’s on 12v through an Mtronic 30 amp ESC. So what wire would you recommend and where from please?
-
Check out component shop on the internet, they may sell suitable wire by the meter...
-
Yes, Component Shop. Their very flexible silicon wire is ideal and the 12 or 14swg sizes should be fine. Continuous current ratings are given but not at what voltage.

Thanks guys. Just bought a roll of red and one of black - 12 gauge. Not sure how much on a roll but it looks quite a bit. Now I think I need a new soldering iron to get enough heat into that multi strand stuff!!
-
Glynn Guest has reminded me that the current carrying capacity of wire doesn't vary with the voltage - I was proably confusing it with switch contacts where high voltage can cause arcing.
Simon, yes, that wire does need quite a bit of heat to solder! However you can use Wago connectors for some joints. Have a look at post #65 onwards on this thread:

I’m afraid I’m old fashioned Colin, I like solder but I’ll use chocolate block connectors in between the motors an speed controllers and I really aught to fit fuses between motor and esc to protect the esc’s - too expensive to fry!!

Hi
Over the years I have picked up a lot of different leads that are used with computer's, that is what I use to wire the motors in my boats, if it can take 240 volts then it can take 6/12 volts.

Fair point Fred but I tend to worry more about the amps than the volts! The stuff I've ordered should be fine though. Now Ive got to find a charger for my Planet T5 transmitter. Bought 15 years ago and not powered up until today. Only 4 x AA's, very odd in my book!! And a 1.5mm pin in the Tx socket so I'm scrabbling around to find a 4.8v charger with that sort of plug!!

If they are individual AA cells and it is a 2.4Ghz TX you might as well just use alkaline cells. Better voltages and last a long time.
Another alternative which I use is the low self discharge rechargeables:

I just use a plug in wall charger to charge them out of the Transmitter.

If you have an independent motorists supply shop nearby they are a good source of electrical things we use including wiring, fuses etc. Otherwise I use The Component Shop for batteries.
Do not be seduced by cheap batteries from China! What is printed on the battery is mainly fiction.

Thanks Colin, I'm so used to the idea of plugging a charger into the Tx and the thought that taking batteries out of tx's regularly isn't a good idea! But at that price for 4 AA's thats cheap as hinds. Ive actually got 4 1300Mah AA's in a wall charger right now so I may live with that but if I can find a suitable charger - for about £5 I imagine? - then I'll got for it!

Thanks Roy. I was thinking about Halfords or an independent for some spade connectors! I need to have a dig through my existing radio gear to see what I already have - its been awhile!
