If you love RC, you see the position of a battery. The type of successions you choose, how fine your pack is collected and how efficiently you responsibility them are all vital characteristics to driving your RC automobile. Sure, you can buy a battery-operated packet pre-assembled, but you can likewise build your own and get the consummation of conniving and set in motion your own van.
The first thing you need to do is when you decide to put together a battery pack is what you are powering and how much juice you need. You also need to think about the following:
1. Look at the chassis of your vehicle. The kind of vehicle doesn’t matter as much as the amount of space in which you have to maneuver. The batteries may need to be oriented in a flat pack, a clustered pack or as both. You should also think about the distribution of weight in your vehicle – whether the battery weight is going to be distributed in a side to side or back to front manner. In some cases your chassis space for a battery pack is not adaptable, so be aware of those constraints before you start.
2. Look at the motor powering your RC vehicle. Depending on the power requirements, you’ll be able to determine how many batteries or cells you need. This is also when you can decide the type of batteries you’ll use – if you want to keep your NiMH batteries or upgrade to LiPo.
3. Determining your voltage is really a simple matter of addition. A standard cell voltage is 1.2v, so wired in a series – 12 batteries will add up to 14.4v – which would power an 14.4 volt RC electric motor.
Next, you’ll need to gather your battery pack supplies – so here’s a sample shopping list. Remember, we’re assuming we’re creating a battery pack with 14.4v, as in the example above:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you can order battery bars in bulk if you plan to build more than one pack and save $)
o Wire: You’ll want a higher quality 12 gage with a high strand count. This type of wire, with these characteristics will be more flexible which is ideal as well as being more efficient for power transmission.
o 80-100 Watt Soldering Gun. You’ll want a gun because you can be more exact and quicker – this is necessary because of the heat sensitivity of batteries. The faster and more specific you can be, the less likely you’ll be to damage the battery.
o 60/40 Solder. This is higher quality – also important for quick and accurate work and avoiding battery damage.
o Flux. This is a chemical cleaning agent that removes oxidation from metal to facilitate soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will be used to bundle the batteries together.
o Battery Pack Assembly Jig – optional. These assembly devices align the batteries properly and facilitate a tidy battery pack. The batteries end up basically looking like cord wood – tidily bundled.
o Soldering “Helping Hands” – optional. These devices allow you to hold things in place while you solder.
o Another optional timesaver is to get a “Helping Hands” accessory for your soldering station.
o Multi Meter. You need a good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools will help you handle, strip and properly cut your 12 gage wire.
o The final component is the shrink wrap which will go around the entire assembly and keep it tidy. You’ll also need a heat gun to heat and shrink the wrap.
So, you’ve identified how to orient your batteries and how many you need – now you get to work on assembly. For this example, we’re assembling 12 battery cells – 6 down one side and 6 down the other.
Once you identify where the batteries are going in relation to your chassis and how they are going to be laid out, you can begin. For this example, let’s say we’re doing 6 down one side and 6 down the other side.
Just to make sure we’re on the same page, the ultimate goal here is to be running wire from the positive terminal of your first battery to the positive terminal on the electric RC motor and then running a wire from the negative terminal on the last battery in your pack to the positive terminal of your other battery pack, thereby creating a completed circuit.
This mean you need to have sufficient wire to reach from the positive terminal of your first battery to that terminal and likewise from the negative to complete the circuit with your other battery pack so bear that in mind.
Orientation. Align your first cell so that positive is pointing “upwards” and negative is pointing “downwards” and then reverse the next battery so it’s opposite on down the line. If you purchased the battery assembly jig, this is when you’d use it to align your cells and hold them in place.
Adhere. Stick all the batteries together with your fast drying adhesive to they are in order and aligned properly.
The ropes requirement to be pre-tinned which mean you prerequisite to sliver off a area creep of the protecting soft electric wiring sheath, use the fluidity to unsoiled them – smear the fluctuation abundantly – temperature your repair gun and formerly temperature the wire and current the link addicted to the wire while waiting for methodically flooded. You’ll too famine fuse on the series so the join resolve act as the connector by the cordless.
