Which Connectors are the best?

   Over the years I have been racing radio controlled model cars of all descriptions, I have tried a number of different connectors for my batteries.

   My first car was a Tamiya Boomerang, and of course the batteries I used all had the standard Tamiya connectors, which were fine with the kit supplied 27T silver can electric motor, but I soon discovered their problem when I installed my first Modified motor. The high current demands of the motor created so much heat, the plastic surround of the connectors melted and fused together. No matter how I tried they could not be disconnected. My only option was to cut the wires.

   From there I moved over to Corally connectors, commonly referred to by many now as Bullet connectors. Comprising of a short length of 4mm gold plated tube at one end, and what looks like what we used to call a Chinese lantern fitting that slotted inside the tube, also gold plated. Although they were highly efficient and reasonably easy to install and use, I never really took to this type of connector, I think it was the fact that there was always the possibility of the positive and negative being connected wrongly in poor light, and also that if positioned side by side, each connector could work loose and become exposed, leaving the possibility of a short circuit.

   Then I remember buying some second hand batteries at an area meeting one day, they had these little red block connectors I soon learned were "Deans" rated at around 40 Amps. They looked like just what I was looking for so I gave them a try. They worked fine, although I didn't like the shortness of the part to be soldered. However, for about two years they were my connector of choice, until I stumbled across an advert in the "Radio Race Car International" magazine.

   The latest development in connectors at that time were named "Power Pole", made by a company called Anderson, and were rated at 45 Amps. The design uses a small tube, plated with silver, with a short extending lip, that slots over the exposed wire, and can either be crimped onto the wire or soldered. For safety and efficiency, I prefer the latter. To complete the connector, a colour coded plastic cover fits neatly over it.

   It was way back in 1995 I first used Power-Pole, and to this day they are still the most efficient I have come across and never overheat.

   So, if you are looking for a connector to change over to, that has a high current rating and won't cause you any overheating problems "Anderson Power Pole" is the one I recommend.

Hints and Tips

How to Charge Rechargeable Batteries
for Radio Controlled Models

Ni-Cad (Nickel Cadmium) Batteries

1/  All Ni-Cad Batteries have to be Discharged soon after use. This is to avoid the dreaded "Memory" effect that on subsequent re-charges can cause a momentary drop in performance during a race. A simple discharger can be made from a car 12v bulb.

2/  Try to time your charge to complete just before a race. This will ensure maximum punch and duration. If a Ni-Cad is left to cool after a charge this advantage dissipates.

3/  The higher the charge current the more Punch the Ni-Cad battery will have (up to around 8 amps), however, the downside to this is a reduction in duration and effective battery life.

4/  Ni-Cad Batteries should be left to cool for about an hour after use before recharging. This will increase the effective life of the battery.

Ni-Mh (Nickel Metal Hydride) Batteries

1/  Never charge Ni-Mh batteries at a current higher than 4.5 amps. Although these batteries can give a higher voltage than Ni-Cad Batteries, they are much more sensitive and easy to damage if charged too quickly.

2/  Charging methods for Ni-Mh batteries can also be detrimental. The best I found was the "Slope" method. Avoid "Pulse" charging as this tends to effect crystal formation detrimentally and (it seems to kill them off) thus reduces duration over time.

3/  If using a temperature cut off charger on Ni-Mh batteries set to no more than 40 Degrees Centigrade. Any higher than this can damage the crystals.

4/  It is not necessary to discharge Ni-Mh Batteries. Unlike Ni-Cad batteries they do not develop a memory. Also, if they are totally discharged they sometimes will not charge straight after and need to be coaxed with a 10 minute trickle charge.

5/  Ni Mh Batteries can be recharged shortly after use without any discernable detrimental effects.

Li-Po (Lithium-Polymer) Batteries

1/  Li-Po batteries are a huge step forward in performance compared with Ni-Cad and Ni-Mh batteries. However, care has to be taken when charging. If certain procedures are not followed they could burst into flames or even explode, therefore I do not recommend Li-Po batteries for RC beginners.

2/  Li-Po batteries are more expensive and have a shorter effective life. Generally considered to be between 200 to 400 charge cycles compared to 1000+ for Ni-Cad and Ni-Mh.

3/  Consider a Battery pack listed as "2S 5000Mah 40c 2C".
"2S" is the number of cells in the pack, in this case 2 cells. Each cell provides around 3.7 Volts, so a 2S pack is around 7.4 Volts.
"5000Mah" (Mili-Amp-Hours) is the capacity. The amount of charge the pack can hold.
"40c" is the maximum Discharge rate. Which in our example would be calculated as 5000 (Mah) x 40 = 200000Ma (200 Amps).
"2C" is the maximum Charge rate. 1C being 5 Amps, so in our example 2 x 5 = 10 Amps.

4/  To safely charge your Li-Po Battery I would recommend a good Computerised charger, preferably one that can handle a Charge current of around 25A and always place the charging battery on a fireproof surface.

5/  Finally. NEVER leave your charging Li-Po battery unattended and NEVER EVER charge it above the recommended rate. When not in use, store with around 60% charge remaining in a fireproof box.

How to avoid Interference.

1/  The first consideration when installing your Receiver into your Electrically Powered Model is to make sure it is well away from the Negative Battery terminal, and the Motor. The Magnetic field can cause stuttering type interference at times of high current draw (i.e., Fast Acceleration)

2/  Make sure the Ariel tube is long enough for the Ariel wire. The tip of this wire is highly sensitive and should be as high, and as far away from the Motor as possible (yup, its that magnetic field prob again)

3/  If all else fails, a simple tip that often works for all RC Model enthusiasts is to wrap the receiver in Aluminium Foil, to shield against any magnetic and external radio interference.

4/  As a last resort, to protect against servo twitch, try ferrite beads. (available at Radio Shack or Maplins) These are threaded over the red, white (or yellow) and black wires of each servo.

5/  If you are using a FET Servo, the installation of a choke (a small electrical component) in the positive feed wire will smooth out any current spikes and reduce the possibility of "servo twitch".

6/  Another thing you might try is a "glitch buster" or "stutter stopper". Basically, this is a capacitor that simply plugs into your Radio Receiver and attempts to keep a level voltage supply to the Radio system.
