Can they be recovered?"},"content":{"rendered":"

If your Alta X flight packs are not charging, this may be due to the packs falling to a low voltage state. This can occur due to neglect and lack of maintenance or regular use from flying and charging. You can test the packs with a standard multimeter or by plugging them into your charger. If the main voltage number reads at or below 40v, this is likely the reason for failure to charge.\u00a0<\/span><\/p>\n

There is a method that can be used with caution to attempt a recovery of the batteries and restore their voltage to normal levels. This may then allow the standard charger to recognize them and properly balance charge them again.<\/span><\/p>\n

NOTE: The following recovery method should only be attempted by someone with proper electrical knowledge and steps need to be taken to mitigate fire risk. Charging a battery without a balance charger carries additional risks.<\/b><\/p>\n

The primary risks involved with this recovery method are:<\/b>\u00a0<\/b><\/p>\n

    \n
  1. Trying to charge the batteries too quickly.<\/b><\/li>\n
  2. An individual cell overcharging in the recovery process.<\/b><\/li>\n
  3. Allowing open battery leads to short and spark while connected to battery<\/b><\/li>\n
  4. In the worst case scenario, a fire due to a severely damaged battery.\u00a0<\/b><\/li>\n<\/ol>\n

    Please attempt initial recovery at your own risk with batteries on a concrete or similar\u00a0 non flammable surface and away from flammable materials. With cautions noted, this has proven to be a successful method of recovering low state of charge Alta X flight batteries.\u00a0<\/b><\/p>\n
