Building an RC Battery Pack - A Standard How-To
If you love RC, you know the importance of a battery pack. The kind of batteries you select, how properly your pack is assembled And just how proficiently you demand them are all crucial elements to powering your RC automobile. Sure, You should purchase a battery pack pre-assembled, but You may as well Create your own and acquire the gratification of planning and powering your very own motor vehicle.
The very first thing you might want to do is when you decide To place with each other a battery pack is what you are powering and how much juice you would like. In addition, you require to think about the next:
one. Think about the chassis within your vehicle. The type of vehicle won't make a difference as much as the quantity of Room through which You need to maneuver. The batteries may possibly should be oriented in a flat pack, a clustered pack or as the two. It's also wise to consider the distribution of bodyweight in the automobile - if the battery weight will be dispersed inside a side to aspect or again to entrance manner. In some instances your chassis House for any battery pack isn't adaptable, so know about those constraints Before you begin.
two. Think about the motor powering your RC car. With regards to the power needs, you can figure out what number of batteries or cells you may need. This is also once you can come to a decision the type of batteries you may use - in order to keep your NiMH batteries or improve to LiPo.
three. Deciding your voltage is known as a uncomplicated issue of addition. An ordinary cell voltage is one.2v, so wired within a series - 12 batteries will include approximately 14.4v - which would ability an 14.four volt RC electric powered motor.
Future, You will need to collect your battery pack supplies - so Here is a sample searching record. Bear in mind, we're assuming we're creating a battery pack with fourteen.4v, as in the example above:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you'll be able to purchase battery bars in bulk if you plan to construct more than one pack and conserve $)
o Wire: You'll want a higher quality twelve gage using a superior strand depend. Such a wire, Using these attributes will be far more flexible which is right in addition to currently being more efficient for electricity transmission.
o eighty-a hundred Watt Soldering Gun. You will need a gun since you might be extra exact and more quickly - this is important because of the warmth sensitivity of Automated Guided Vehicles (AGV) Battery batteries. The quicker and much more certain it is possible to be, the less likely You will be to wreck the battery.
o sixty/40 Solder. This is often increased top quality - also crucial for rapid and precise do the job and preventing battery harm.
o Flux. It is a chemical cleansing agent that removes oxidation from metallic to aid soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive is going to be accustomed to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries effectively and facilitate a tidy battery pack. The batteries end up mainly looking like twine Wooden - tidily bundled.
o Soldering "Assisting Palms" - optional. These units help you maintain issues in place When you solder.
o A further optional timesaver is to obtain a "Aiding Hands" accessory for your soldering station.
o Multi Meter. You need a excellent multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These tools will allow you to manage, strip and effectively Lower your 12 gage wire.
o The ultimate component may be the shrink wrap which is able to go round the overall assembly and preserve it tidy. You are going to also need a heat gun to warmth and shrink the wrap.
So, you have recognized the way to orient your batteries and the quantity of you will need - now you can get to operate on assembly. For this example, we are assembling 12 battery cells - 6 down a single aspect and six down another.
When you finally identify where by the batteries are heading in relation to your chassis And the way they're going to get laid out, you could start off. For this example, for example we're accomplishing 6 down a person side and 6 down another aspect.
Just to verify we are on the same site, the last word aim here is to get running wire through the constructive terminal within your first battery for the favourable terminal on the electric RC motor then managing a wire within the unfavorable terminal on the final battery as part of your pack to your good terminal of your other battery pack, therefore making a completed circuit.
This indicate you need to have sufficient wire to achieve in the good terminal of the first battery to that terminal and likewise in the unfavorable to finish the circuit with your other battery pack so bear that in mind.
Orientation. Align your very first cell so that good is pointing "upwards" and damaging is pointing "downwards" and afterwards reverse the next battery so it's opposite on down the line. If you purchased the battery assembly jig, this is if you'd use it to align your cells and hold them set up.
Adhere. Adhere many of the batteries along with your quick drying adhesive to They are really if you want and aligned effectively.
Flux. Use your flux now to the relationship points.
Relationship - Use your battery bars to connect your cells. You will need to heat up your soldering gun and heat up the battery bar. Utilizing the bar protects the battery and once the flux starts to bubble, you hire your use of solder. The target is to NOT heat the battery alone. Heating the battery is not merely counterproductive, given that if you hurt the battery it will not do the job, but also unsafe since the mobile could explode if overheated.
You'll want to finish a similar steps to the remaining battery connections. You happen to be connecting the detrimental to the beneficial repeatedly again. You may then be ready to attach wiring towards your battery pack.
The wires must be pre-tinned which necessarily mean you'll want to strip off 1 / 4 inch of the protective plastic wiring sheath, make use of the flux to clean them - utilize the flux liberally - warmth your solder gun then heat the wire and stream the solder into your wire till carefully saturated. You can expect to also want solder to the batteries so the solder will act because the connector Together with the battery.
After the two, six cell battery packs are comprehensive, you'll want to hire the shrink wrap to protected them - and you will have your comprehensive battery pack! Now you'll ability and fly your RC helicopter, aircraft, boat, vehicle or truck without any problems!
