How should I look after my batteries?
To get the best performance and life out of your batteries, you need to treat them right. Alkaline batteries commonly used to power transmitters are quite hardy, but we always recommend removing them from your controller if you do not intend to use the device for a long period. NiMh batteries are also robust but can be damaged by overcharging so investing in a quality monitoring charger is wise. There is no need to fully discharge and recharge them and they should be stored in a cool location LiPo batteries are more sensitive and thus precautions should be taken when handling and charging them. A high quality charger that utilises the balance lead and reduces its current when the peak cell voltage is reached is recommended. Whilst LiPo batteries can be charged at high rates, the safest rate is 1C, literally one times the capacity of the battery in amps. For example a 3000mAh battery should ideally be charged at 3Amps. Avoid leaving a charging LiPo battery unattended and store them in LiPo safe bags when not in use. LiPo batteries should be stored at 3.8v per cell (down from 4.2v) to maximise their life, many chargers offer a 'storage' charge function to achieve this. A tool like this Emax Digital Battery Capacity Checker is perfect for checking the charge and also the balance of cells within LiPo batteries.

Why is it easy to overcharge a lithium ion battery?
For lithium-ion and lead-acid batteries, it is easy to control overcharge because you are required to set a maximum charge voltage. The nickel-based cells lack a float charge voltage so the charging is based on forcing current through the battery. For other batteries, the energy is fixed in stone, but for NiMH, that not the case.
How much charge does a nickel battery have?
The charge efficiency of nickel-based batteries is close to 100% up to 70% charge. The pack remains calm, but it begins to warm up with decreased ability when it gets closer to a complete charge.
Why is it so hard to charge a battery in parallel?
Parallel charging makes the cells and batteries hard to charge in parallel. This is because you can’t be sure that every cell is the same impedance, and so some will take more current than others even when they are full. Meaning you need to use a different charging circuit for every string in a parallel pack or balance the flow in some other way.
How to keep batteries from getting damaged?

Traxxas NiMH batteries are offered with 6 cells (7.2 volts), 7 cells (8.4 volts) or 8 cells (9.6 volts).
How does a LiPo battery work?
It takes a little longer to balance charge a battery, but doing so ensures that you’ll get the longest run time from each charge. Balance charging also helps extend your LiPo battery’s overall life by preventing over-discharging. Low-Voltage Detection in all Traxxas speed controls is designed to alert you when the battery’s voltage drops below 3.2 volts per cell; however, the speed control reads total pack voltage and not the voltage of individual cells. For example, if you plug a 3-cell LiPo into your speed control, the speed control will alert you if the battery voltage drops below 9.6 volts (3.2 x 3 = 9.6). But if your battery is not balanced, that 9.6 volts might actually represent individual cell voltages of 3.3v, 3.3v, and 3.0v. The 3.0v cell has been over-discharged, which shortens the life of the pack. Balance charging your LiPo packs assures each cell is equally charged so their voltages will match as the cells discharge.
What is a niMH battery?
NiMH battery packs are composed of cylindrical 1.2-volt cells, similar to the AA, C, and D batteries that we’re all used to installing in flashlights, TV remotes, and other devices. The rolled-metal construction of the individual cells, and the double-welded tabs Traxxas uses to connect the cells, makes them extra rugged. NiMH batteries can be discharged completely without harming the battery, and they do not need to be charged before storage. Traxxas NiMH batteries are offered with 6 cells (7.2 volts), 7 cells (8.4 volts) or 8 cells (9.6 volts).
