Making an RC Battery Pack - A Simple How-To
If you like RC, you understand the significance of a battery pack. The kind of batteries you decide on, how properly your pack is assembled and how effectively you charge them are all essential facets to powering your RC motor vehicle. Absolutely sure, you can buy a battery pack pre-assembled, but You may as well Establish your very own and obtain the gratification of developing and powering your own private car.
The very first thing you need to do is when you select To place jointly a battery pack is what you're powering and just how much juice you may need. Additionally you require to think about the following:
1. Think about the chassis of one's motor vehicle. The type of automobile doesn't matter just as much as the quantity of Place through which You should maneuver. The batteries could need to be oriented in the flat pack, a clustered pack or as both of those. You should also give thought to the distribution of excess weight within your automobile - whether or not the battery excess weight will probably be dispersed inside of a aspect to side or back again to entrance manner. In some instances your chassis Room for just a battery pack is not really adaptable, so pay attention to Those people constraints before you start.
two. Look at the motor powering your RC auto. With regards to the ability needs, you can identify the number of batteries or cells you may need. This is certainly also any time you can decide the type of batteries you can expect to use - if you would like keep the NiMH batteries or upgrade to LiPo.
3. Determining your voltage is known as a basic subject of addition. An ordinary cell voltage is one.2v, so wired within a series - 12 batteries will incorporate up to fourteen.4v - which might power an 14.4 volt RC electrical motor.
Upcoming, You'll have to assemble your battery pack supplies - so This is a sample searching listing. Bear in mind, we are assuming we are developing a battery pack with fourteen.4v, as in the instance above:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you could get battery bars in bulk if you propose to create multiple pack and preserve $)
o Wire: You'll want a higher high quality twelve gage which has a substantial strand depend. Such a wire, Using these features might be a lot more flexible which is ideal along with remaining far more economical for power transmission.
o 80-100 Watt Soldering Gun. You will need a gun since you might be far more actual and faster - this is important due to heat sensitivity of batteries. The more quickly and a lot more certain you'll be able to be, the not as likely You will be to wreck the battery.
o 60/forty Solder. This really is better quality - also vital for fast and precise function and preventing battery problems.
o Flux. This is the chemical cleansing agent that removes oxidation from metal to facilitate soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive will probably be utilized to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries effectively and facilitate a tidy battery pack. The batteries end up mainly wanting like cord wood - tidily bundled.
o Soldering "Encouraging Palms" - optional. These gadgets help you hold things in place As you solder.
o A different optional timesaver is to get a "Helping Hands" accent to your soldering station.
o Multi Meter. You'll need a very good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These tools will help you manage, strip and properly Slash your 12 gage wire.
o The final ingredient is the shrink wrap that can go across the full assembly and hold it tidy. You will also need a warmth gun to heat and shrink the wrap.
So, you have recognized the best way to orient your batteries and how many you would like - now you get to operate on assembly. For this example, we are assembling 12 battery cells - 6 down one particular facet and six down one other.
When you finally recognize where by the batteries are likely in relation towards your chassis and how they are going to get laid out, you could start out. For this example, as an instance we are accomplishing 6 down a person facet and 6 down another facet.
Just to ensure we're on precisely the same web page, the ultimate purpose Here's to be running wire from the optimistic terminal of your first battery towards the good terminal on the electric RC motor and after that working a wire within the damaging terminal on the last battery with your pack on the good terminal of your respective other battery pack, therefore developing a accomplished circuit.
This signify you need to have adequate wire to reach through the constructive terminal of your respective 1st battery to that terminal and Furthermore with the adverse to complete the circuit along with your other battery pack so bear that in your mind.
Orientation. Align your 1st mobile to ensure favourable is pointing "upwards" and adverse is pointing "downwards" and afterwards reverse another battery so It can be reverse on down the line. If you purchased the Automated Guided Vehicles (AGV) Battery battery assembly jig, This is often if you'd utilize it to align your cells and maintain them in position.
Adhere. Stick every one of the batteries along with your fast drying adhesive to They're if you want and aligned adequately.
Flux. Use your flux now about the link factors.
Link - Use your battery bars to attach your cells. You'll have to warmth up your soldering gun and warmth up the battery bar. Using the bar protects the battery and in the event the flux begins to bubble, you make use of your usage of solder. The goal is not to heat the battery by itself. Heating the battery is don't just counterproductive, considering the fact that in case you destruction the battery it will not work, but in addition harmful because the mobile may explode if overheated.
You will need to accomplish the same measures to the remaining battery connections. You are connecting the unfavorable towards the optimistic over and over yet again. You may then be ready to connect wiring to the battery pack.
The wires must be pre-tinned which signify you'll want to strip off 1 / 4 inch on the protective plastic wiring sheath, use the flux to wash them - implement the flux liberally - heat your solder gun after which you can warmth the wire and movement the solder to the wire until eventually extensively saturated. You can also want solder around the batteries Hence the solder will act as being the connector Using the battery.
As soon as the two, six cell battery packs are finish, you will need to utilize the shrink wrap to safe them - and you'll have your full battery pack! Now you'll be able to electricity and fly your RC helicopter, airplane, boat, car or truck or truck without any complications!
