Building an RC Battery Pack - A Simple How-To
If you like RC, you are aware of the value of a battery pack. The type of batteries you decide on, how perfectly your pack is assembled And exactly how effectively you charge them are all critical facets to powering your RC motor vehicle. Positive, You should buy a battery pack pre-assembled, but It's also possible to build your personal and acquire the satisfaction of creating and powering your own personal car.
The first thing you must do is when you decide to put collectively a battery pack is what you're powering and the amount of juice you would like. Additionally you require to consider the subsequent:
one. Consider the chassis of the motor vehicle. The kind of car or truck doesn't subject as much as the quantity of Place wherein You need to maneuver. The batteries may possibly must be oriented within a flat pack, a clustered pack or as each. It's also advisable to think of the distribution of body weight in your car - if the battery pounds is going to be distributed inside a side to facet or back to front manner. Occasionally your chassis Room for any battery pack isn't adaptable, so pay attention to All those constraints before you start.
2. Look at the motor powering your RC motor vehicle. Depending on the electric power prerequisites, you'll be able to determine the quantity of batteries or cells you need. This really is also if you can make your mind up the sort of batteries you can expect to use - if you would like keep the NiMH batteries or enhance to LiPo.
three. Deciding your voltage is mostly a straightforward make any difference of addition. A standard mobile voltage is 1.2v, so wired in the collection - twelve batteries will add as much as fourteen.4v - which might energy an 14.four volt RC electrical motor.
Next, You'll have to gather your battery pack materials - so here's a sample buying list. Bear in mind, we are assuming we're making a battery pack with 14.4v, as in the instance earlier mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you are able to purchase battery bars in bulk if you propose to construct multiple pack and conserve $)
o Wire: You'll be wanting a greater top quality 12 gage that has a significant strand count. This type of wire, Using these qualities will probably be a lot more versatile which is ideal along with staying far more efficient for electricity transmission.
o eighty-one hundred Watt Soldering Gun. You'll want a gun because you is usually more actual and more rapidly - this is necessary due to the warmth sensitivity of batteries. The quicker and much more precise you could be, the less likely You will be to break the battery.
o sixty/forty Solder. This can be greater good quality - also critical for brief and exact work and avoiding battery damage.
o Flux. It is a chemical cleaning agent that gets rid of oxidation from metallic to aid soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive will probably be used to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries effectively and aid a tidy battery pack. The batteries wind up in essence on the lookout like cord Wooden - tidily bundled.
o Soldering "Serving to Arms" - optional. These equipment enable you to hold factors in position while you solder.
o Yet another optional timesaver is to secure a "Supporting Hands" accessory for your personal soldering station.
o Multi Meter. You'll need a fantastic multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These applications will let you take care of, strip and appropriately Slice your 12 gage wire.
o The final part is definitely the shrink wrap that can go around the total assembly and continue to keep it tidy. You can also have to have a warmth gun to warmth and shrink the wrap.
So, you have recognized how you can orient your batteries and the quantity of you need - now you receive to work on assembly. For this instance, we are assembling 12 battery cells - six down a person aspect and 6 down the other.
Once you establish where by the batteries are likely in relation to the chassis And the way they're going being laid out, you may start out. For this example, as an example we're undertaking 6 down one facet and 6 down the other aspect.
Just to make sure we are on the exact same site, the final word aim Automated Guided Vehicles (AGV) Battery here is to be functioning wire from your favourable terminal of the initial battery to the constructive terminal on the electric RC motor after which you can jogging a wire from the damaging terminal on the last battery with your pack for the favourable terminal of your respective other battery pack, therefore developing a completed circuit.
This imply you might want to have enough wire to achieve in the favourable terminal within your 1st battery to that terminal and Furthermore from the unfavorable to complete the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your initially cell so that favourable is pointing "upwards" and adverse is pointing "downwards" after which reverse another battery so It is opposite on down the line. If you purchased the battery assembly jig, This is certainly after you'd utilize it to align your cells and hold them set up.
Adhere. Adhere each of the batteries along with your fast drying adhesive to They are really in order and aligned adequately.
Flux. Use your flux now around the link points.
Connection - Use your battery bars to attach your cells. You will need to warmth up your soldering gun and heat up the battery bar. Utilizing the bar shields the battery and when the flux begins to bubble, you hire your usage of solder. The aim is to NOT warmth the battery alone. Heating the battery is not merely counterproductive, since in case you destruction the battery it will not likely perform, but additionally harmful as the mobile may explode if overheated.
You will need to accomplish precisely the same methods for that remaining battery connections. You're connecting the unfavorable to your favourable again and again once again. You may then be All set to connect wiring on your battery pack.
The wires need to be pre-tinned which signify you need to strip off 1 / 4 inch from the protecting plastic wiring sheath, utilize the flux to clean them - apply the flux liberally - heat your solder gun then warmth the wire and stream the solder in the wire until totally saturated. You can also want solder on the batteries And so the solder will act given that the connector While using the battery.
When the two, six cell battery packs are comprehensive, you'll want to use the shrink wrap to secure them - and you'll have your entire battery pack! Now you can ability and fly your RC helicopter, aircraft, boat, auto or truck without any difficulties!
