Buying Guide
I have described each product in the upper section. It is normal to be confused. You may still be puzzled about which battery to choose. This is why I have looked into a few aspects you should check before buying.
So that you can pick the best one for you.
Lipo vs NiMH Battery: Which One is Better?
Both batteries are great on their own way. Also, both of them have their benefits and drawbacks. However, between Lipo and NiMH, Lipo battery is the better one.
Lipo Battery
Lithium polymer batteries offer greater speed, and more “punch” off the line. Also, they provide more stable power throughout the run. They have a higher energy density with a high discharge rate. In addition, they have a flat cell design.
However, if not used properly, these can cause danger. It also needs a balanced charger with an ESC. besides, they are pricier than NiMH batteries.
NiMH Battery
Nickel-Metal Hydride batteries offer more reliability and safety. Also, they cost cheaper than NiMH batteries. These are easy to maintain. Additionally, they have smaller voltage increments.
Here, these batteries are heavier and bulkier. Also, these are less efficient than Lipo batteries.
So, even though it costs more, Lipo battery is the better one. As we all know, good stuff comes at a higher price.
What is the Voltage Capacity?
To find out how much voltage a battery contains, always check the label. You can have a two-cell LiPo battery, and each can have 4.2 volts. In this case, the total supply will be 8.4 volts.
Given that each type of electronic device has different needs. Knowing the battery pack’s voltage will help you choose the right one.
Suppose your RC car has a brushed motor. And you purchase a 12.6V battery; you will shorten the life of the battery. The motor will degrade quickly.
The fact that power capacity can be altered to meet your demands is another crucial aspect. Just be sure your machine can withstand the higher voltage before updating.
Well, there are a few more facts you must have to consider before purchasing a battery for Traxxas Slash. Those includes the runtime, capacity, discharge rate, power ci=onsumption, and others. Make sure to check them as well.
FAQs
Can You Revive a LiPo Battery Back to Life?
To save your battery, you will need an exhausted LiPo battery. Fully draining a LiPo battery causes the cells to oxidise. This contributes to the battery’s poor performance. But if you react quickly enough, you can generally save the battery. That too, without suffering too much performance loss.
Which One is Better Between a 2S and 3S LiPo?
It depends on the voltage rating. A brushless motor with a 3,500kV rating will turn at 3,500 RPM. It is for every volt you put to it. That motor will rotate at about 25,900 RPM on a 2S LiPo battery. It will rotate at 38,850 RPM on a 3S. The more voltage you have, the faster you will go.
How Long Can LiPo Batteries be Left Fully Charged?
You should never keep your LiPo batteries fully charged for longer than two to three days. If, on the third day, you decide you won’t be using your battery today, store it. You must not take it out until you are ready to use it once again. Because it might drain the battery slowly.
Endnote
The discussion has ended after all. In the above, I have tried my best to provide you with a thorough review of each battery. I hope it will be helpful for you to find the best battery for Traxxas Slash.
You can go for either a NiMH or Lipo battery. It all depends on your preference.
All the best!
