Making an RC Battery Pack - A Basic How-To
If you love RC, you already know the value of a battery pack. The type of batteries you end up picking, how effectively your pack is assembled And the way competently you demand them are all vital elements to powering your RC automobile. Confident, You should buy a battery pack pre-assembled, but You may also Develop your own personal and get the fulfillment of planning and powering your personal vehicle.
The first thing you have to do is when you decide To place collectively a battery pack is what you are powering and just how much juice you need. You furthermore may want to think about the subsequent:
1. Look at the chassis of your vehicle. The kind of car or truck won't issue around the amount of Room through which You will need to maneuver. The batteries might need to be oriented in a flat pack, a clustered pack or as both of those. It's also advisable to contemplate the distribution of excess weight in the car - whether the battery bodyweight is going to be distributed inside of a side to facet or again to front fashion. In some instances your chassis Place for just a battery pack is not adaptable, so be aware of Individuals constraints Before you begin.
two. Think about the motor powering your RC motor vehicle. Depending upon the power demands, you can determine the number of batteries or cells you would like. This is also whenever you can determine the sort of batteries you can expect to use - if you want to keep your NiMH batteries or enhance to LiPo.
three. Pinpointing your voltage is mostly a very simple issue of addition. A normal cell voltage is 1.2v, so wired in a very series - twelve batteries will include as much as fourteen.4v - which might electrical power an 14.4 volt RC electric motor.
Up coming, you'll need to assemble your battery pack provides - so here's a sample searching checklist. Don't forget, we are assuming we are creating a battery pack with 14.4v, as in the instance higher than:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to order battery bars in bulk if you intend to construct multiple pack and preserve $)
o Wire: You will need the next top quality 12 gage which has a significant strand count. This sort of wire, Using these qualities is going to be additional adaptable which is right and currently being far more effective for power transmission.
o 80-a hundred Watt Soldering Gun. You'll be wanting a gun simply because you is often much more actual and quicker - this is important because of the heat sensitivity of batteries. The more rapidly and more particular you can be, the less likely You will be to wreck the battery.
o 60/forty Solder. That is larger high-quality - also vital for swift and exact do the job and staying away from battery injury.
o Flux. It is a chemical cleansing agent that eliminates oxidation from metal to facilitate soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying adhesive is going to be used to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries effectively and aid a tidy battery pack. The batteries turn out fundamentally seeking like wire Wooden - tidily bundled.
o Soldering "Supporting Palms" - optional. These products allow you to maintain factors in position When you solder.
o One more optional timesaver is to get a "Aiding Arms" accent for the soldering station.
o Multi Meter. You need a very good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These resources will help you deal with, strip and adequately Lower your 12 gage wire.
o The ultimate part will be the shrink wrap which will go across the overall assembly and retain it tidy. You are going to also require a warmth gun to heat and shrink the wrap.
So, you have determined tips on how to orient your batteries and the number of you'll need - now you can get to operate on assembly. For this instance, we're assembling twelve battery cells - 6 down 1 facet and six down the other.
Once you discover where the batteries are heading in relation to the chassis And just how they are going to become laid out, you can commence. For this example, for example we're accomplishing six down one particular facet and 6 down the opposite facet.
Just to be certain we are on the exact same page, the ultimate aim here is to become functioning wire through the good terminal of the very first battery towards the constructive terminal on the electric RC motor and after that running a wire from the adverse terminal on the last battery inside your pack to your favourable terminal of your other battery pack, therefore making a concluded circuit.
This imply you might want to have sufficient wire to reach in the beneficial terminal of one's initial battery to that terminal and Furthermore from the unfavorable to complete the circuit along with your other battery pack so bear that in your mind.
Orientation. Align your initial cell so that favourable is pointing "upwards" and negative is pointing "downwards" after which you can reverse the next battery so It is really opposite on down the road. If you purchased the battery assembly jig, this is if you'd utilize it to align your cells and hold them set up.
Adhere. Stick the many batteries along with your rapidly drying adhesive to They are really if you want and aligned correctly.
Flux. Use your flux now on the relationship details.
Connection - Use your battery bars to connect your cells. You'll have to warmth up your soldering gun and heat up the battery bar. Using the bar guards the battery and once the flux begins to bubble, you employ your utilization of solder. The purpose is to NOT heat the battery by itself. Heating the battery is not merely counterproductive, since in the event you damage the battery it would not function, but also dangerous since the cell could possibly explode if overheated.
You will need to complete exactly the same steps for that remaining battery connections. You might be connecting the destructive into the beneficial again and again all over again. You'll then be Completely ready to connect wiring to the battery pack.
The wires should be pre-tinned which mean you might want to strip off a quarter inch from the protective plastic wiring sheath, make use of the flux to wash them - utilize the flux liberally - heat your solder gun after which you can warmth the wire and movement the solder into the wire until comprehensively saturated. You are going to also want solder to the batteries so the solder will act as being the connector Together with the battery.
Once the two, 6 cell battery packs are entire, you will need to utilize the shrink wrap to safe them - and you'll have your comprehensive battery pack! Now you'll energy and fly your RC helicopter, airplane, boat, vehicle or truck Automated Guided Vehicles (AGV) Battery without any problems!
