1. Which Robot are You Using?
Battery Care & Charging
LiPo batteries are excellent for delivering consistent power throughout the duration of each charge cycle. Follow these instructions to ensure you maximize battery longevity, enjoyment and safety.
Your EZ-Robots includes a Balance Charger for the 7.4v LiPo battery including AC/Mains adapters for international countries.
Charge Before First Use
EZ-Robots are shipped with the LiPo batteries partially charged. The battery must be fully charged before using it. Not fully charging the LiPo battery before use may reduce maximum capacity and is detrimental to the longevity of LiPo batteries.
Disconnect After Charged
Keeping a battery connected to the charger after it has fully charged may drain the battery. Disconnect the battery from the charger once the charging process has completed.
LiPo stands for Lithium Polymer or Lithium-ion Polymer. LiPo batteries should never be drained past the battery monitor limits. The EZ-B v4 includes a battery-saver feature that audibly notifies you when the battery is low and needs charging. This feature will also not allow any further use of the robot until it has been charged.
Upon hearing the verbal "low battery" indicator, the robot needs to be shut off immediately, to avoid draining the battery. Disabling the battery monitor increases the risk of damaging the LiPo.
When a LiPo battery is drained below the recommended threshold, it will begin to "puff up" and swell. A swollen/puffy battery not only performs poorly but may become unsafe and possibly cause a fire.
*Warning: Do not turn on your robot's power switch while the battery charger is connected to the battery. Doing so may cause the battery to overheat and become damaged, leading to a fire.
For optimal battery performance, provide a 30-minute minimum cool-down period after use, prior to recharging the battery. Cool the battery and robot away from direct sunlight before charging. Batteries may be recharged many times per day when a 30-minute cool down period is provided.
Optionally, you can buy replacement batteries from the shop.
Connect the battery charging cable into the balance charger port. The images below show where to find the battery charging cable on all three Revolution robots bodies.
The latest EZ-Robot charger is also the easiest and most reliable. Instructions for this charger are very straight forward. Connect the charger to the AC Mains power outlet and verify the power LED is lit. Connect the battery to the appropriate charger port. The charging status LEDs are detailed below.
Power (Red): Power
Charging (Red): Currently Charging
Charging (Green): Charging Complete
The RED LED indicates that AC/Mains power has been supplied to the charger. If there is not a battery connected to the charger, the GREEN light should be off.
Notice the GREEN light when the battery is charging. The balance charger detects the battery voltage and begins charging the battery when the GREEN light glows.
*Note: The charger will get quite warm (hot in some cases) while the battery is charging. This is normal and depends on how much charging the battery requires.
When the GREEN light stops glowing, the battery is charged. Charging the battery should not take longer than 3 hours. In most cases, it will take less than 1.5 hours to charge from the level of the EZ-B v4's Battery Saver.
