Caring for Your Batteries
Charging Traxxas Batteries
A LiPo battery is said to be “balanced” when each cell is charged to the same voltage. 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.
Maintaining Your Batteries
Inspect your batteries after every use to make sure they have not been damaged. Wipe your batteries down and check for frayed wires, missing insulation, and other signs of damage. Store your batteries in a cool, dry place. If you used LiPo batteries in your vehicle until the Low-Voltage Detection activated, your batteries will be nearing their low-voltage threshold. LiPo batteries should not be left in this depleted state. If you plan to reuse the LiPo batteries that day, recharge them soon after using them. If you do not plan to reuse the batteries immediately, use the Store Mode on your Traxxas iD® charger to prepare them for storage. For optimal performance and long battery life, you should place your batteries in Store Mode once a month.
Millions of devices containing lithium batteries are used and enjoyed daily in devices such as laptops, tablets, smartphones, flashlights, and even full-size automobiles. LiPo batteries are safe and stable as long as caution and common sense are used. However, LiPo batteries can be dangerous if misused or mishandled. Specifically, short circuiting or puncturing a LiPo will result in rapid, destructive discharging and fire. Never, ever intentionally damage a LiPo battery. Over-charging, over-discharging, or improperly charging a LiPo battery will also damage or destroy it. Always use a LiPo-specific charger with LiPo batteries, and choose the correct settings for your battery. Again, Traxxas iD LiPo batteries and a Traxxas iD charger are always the safer, most convenient way to enjoy LiPo battery performance.

In rare cases, a fault or hidden damage in a LiPo battery or a malfunction with a charger can cause the battery to short circuit or over-charge and create the risk of fire with the potential for damage or destruction of the battery and/or property. For this reason, Traxxas recommends LiPo batteries always be charged in a fire-retardant container away from flammable materials and surfaces.
