Batteries cause everything to go in RC, even in nitro-controlled models — sure, the motor consumes fuel, however, you aren’t going anyplace without a battery on board to control the recipient and servos. As with countless numbers parts of our stunning pastime/sport, you can dive super-deep into battery tech on the off chance that it truly interests you — yet it’s not really a necessity for settling on an educated battery decision and understanding the sorts of batteries we use in radio control. Here’s all that you truly need to know…
NiMH and LiPo
There are two fundamental sorts of batteries used to control electric models: Nickel-Metal Hydride (NiMH) and Lithium Polymer (LiPo). The science class names allude to the fundamental materials inside the battery that respond to store and delivery vitality as power, and each has its upsides and downsides.
On the off chance that you purchased a prepared to-run (RTR) model with an included battery, odds are it’s a NiMH. Nickel-metal packs are tough, cheap, and don’t need much in the method of uncommon care. Notwithstanding, they’re heavier than a LiPo battery of comparative voltage and limit (we’ll get to those terms), and their voltage diminishes consistently as the pack is released. When you begin driving, your RC toy car goes slower as time passes. Not perceptibly from the start, yet consistently.
NiMH packs are built with round and hollow cells (normally 6-8 of them) like those we’ve been dropping into spotlights and TV controllers for quite a long time.
LiPo batteries are commonly sold as extras, yet there are RTR models that incorporate them. A LiPo battery is lighter than a NiMH of comparable voltage and limit, which enables your model to feel all the more impressive. Additionally adding to that “sentiment of intensity” (frequently called “punch”) is the LiPo’s capacity to keep up its voltage longer as the pack is drained. Rather than conveying less and less voltage all through your run, a LiPo will hold a consistent voltage for the majority of your run, at that point tumble off rapidly toward the finish of the charge. The drawback is the cost (LiPos are more costly than NiMH, yet the hole is narrowing), and care — LiPos requires a particular care routine for the longest life and safe use.
LiPo batteries are collected with a level piece like cells. Most LiPos utilized in RC cars are 2-or 3-cell designs.
