Developing an RC Battery Pack - A Essential How-To
If you love RC, you recognize the value of a battery pack. The sort of batteries you select, how very well your pack is assembled and how effectively you demand them are all critical facets to powering your RC car or truck. Sure, You should purchase a battery pack pre-assembled, but You can even Make your own personal and have the satisfaction of building and powering your own car or truck.
The very first thing you might want to do is when you decide To place alongside one another a battery pack is what you're powering and exactly how much juice you require. You furthermore may want to consider the next:
one. Look at the chassis of one's motor vehicle. The kind of auto will not make a difference about the amount of space by which You will need to maneuver. The batteries may possibly need to be oriented in the flat pack, a clustered pack or as equally. You should also think of the distribution of excess weight in the automobile - whether or not the battery body Automated Guided Vehicles (AGV) Battery weight will be dispersed in a very side to aspect or back to entrance fashion. Occasionally your chassis Room for a battery pack isn't adaptable, so pay attention to Those people constraints Before you begin.
2. Consider the motor powering your RC car or truck. Dependant upon the ability prerequisites, you'll figure out the number of batteries or cells you would like. This really is also whenever you can come to a decision the sort of batteries you may use - if you'd like to maintain your NiMH batteries or update to LiPo.
three. Determining your voltage is mostly a simple issue of addition. An ordinary mobile voltage is 1.2v, so wired in a sequence - 12 batteries will incorporate nearly 14.4v - which might electrical power an 14.four volt RC electric motor.
Following, You'll have to assemble your battery pack provides - so here's a sample purchasing list. Remember, we are assuming we're developing a battery pack with 14.4v, as in the instance earlier mentioned:
o twelve Batteries or Battery Cells
o twelve Battery Bars (you may get battery bars in bulk if you plan to build multiple pack and help you save $)
o Wire: You will need an increased good quality 12 gage that has a high strand count. This sort of wire, with these attributes is going to be far more adaptable which is right and also currently being a lot more successful for energy transmission.
o eighty-100 Watt Soldering Gun. You'll want a gun because you is usually more correct and faster - this is necessary due to warmth sensitivity of batteries. The more quickly plus more specific you may be, the less likely you'll be to wreck the battery.
o 60/forty Solder. This really is better top quality - also vital for rapid and exact function and averting battery destruction.
o Flux. This can be a chemical cleaning agent that eliminates oxidation from steel to aid soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive is going to be accustomed to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries adequately and aid a tidy battery pack. The batteries end up generally hunting like cord Wooden - tidily bundled.
o Soldering "Aiding Hands" - optional. These products let you maintain items set up while you solder.
o Another optional timesaver is to acquire a "Assisting Palms" accessory for your personal soldering station.
o Multi Meter. You need a great multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These instruments can help you handle, strip and properly cut your twelve gage wire.
o The ultimate part will be the shrink wrap which will go within the complete assembly and retain it tidy. You can also require a heat gun to warmth and shrink the wrap.
So, you've got determined how you can orient your batteries and the quantity of you will need - now you get to operate on assembly. For this instance, we're assembling 12 battery cells - 6 down a person aspect and 6 down the opposite.
After you recognize where by the batteries are heading in relation to your chassis And exactly how they are going to become laid out, you can start off. For this example, for instance we are undertaking 6 down a person facet and 6 down the other side.
Just to make certain we're on the exact same web page, the ultimate aim here is to be managing wire in the beneficial terminal of your respective to start with battery towards the favourable terminal on the electric RC motor after which you can functioning a wire in the unfavorable terminal on the last battery with your pack to the good terminal of your other battery pack, thus making a completed circuit.
This signify you have to have adequate wire to achieve in the positive terminal of one's very first battery to that terminal and Also through the unfavorable to finish the circuit using your other battery pack so bear that in mind.
Orientation. Align your 1st mobile to make sure that constructive is pointing "upwards" and damaging is pointing "downwards" then reverse another battery so it's 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 in position.
Adhere. Stick each of the batteries along with your fast drying adhesive to They're so as and aligned thoroughly.
Flux. Use your flux now within the relationship points.
Link - Make use of your battery bars to connect your cells. You'll have to warmth up your soldering gun and warmth up the battery bar. Using the bar guards the battery and once the flux starts to bubble, you utilize your utilization of solder. The intention is to NOT warmth the battery itself. Heating the battery is not merely counterproductive, given that in the event you hurt the battery it will not perform, but also hazardous as the mobile may well explode if overheated.
You'll want to finish a similar methods for the remaining battery connections. You will be connecting the adverse towards the optimistic time and again once more. You are going to then be Prepared to connect wiring to your battery pack.
The wires must be pre-tinned which imply you must strip off a quarter inch of your protecting plastic wiring sheath, make use of the flux to scrub them - implement the flux liberally - warmth your solder gun and then heat the wire and stream the solder into the wire right up until comprehensively saturated. You can expect to also want solder over the batteries so the solder will act as the connector Together with the battery.
After the two, 6 cell battery packs are comprehensive, you'll want to employ the shrink wrap to safe them - and you will have your total battery pack! Now you'll ability and fly your RC helicopter, plane, boat, vehicle or truck without challenges!
