The Tattu high voltage batteries used in the Ranger Pro should be charged on LiHV, rather than LiPo, which is the default setting on the SKYRC dual battery charger that is packaged with the drone. In the event of a power outage in a location where your charger was plugged in, be sure to change your your charger back to LiHV- as the charger will reset to LiPo when disconnected from power. |
How do I change my battery charger settings to LiHV to charge high voltage batteries, and what is the process of charging the battery?
Hold the up and down arrows on the charger until the setting is changed to LiHV.
Plug in the battery male battery’s XT90 connector to into the female XT90 port on the charger.
Plug the balance port on the battery into the balance port connected to the battery charger.
Change charging to 20A, if the charger is not already set to this value.
Press and hold the start button until the charger beeps. You should get a warning on the screen about charging HV batteries.
Press start one more time to begin charging.

When inserting the battery into the battery tray on the drone, should I have the positive and negative wires facing to the right, or facing to the left?
The positive and negative wires (red and black wires attached to the XT90 battery connector) should be on the right side when inserting into the battery tray.
Additionally, the battery strap should be:
Looped around the left standoff of the entrance to the battery tray. The velcro side should be facing outwards.
Pulled from left to the right, threaded between the positive and negative wires.
Around the right side of the battery, in between the battery and the standoff.
Run back through the battery wires, pulled tight, and pressed firmly against the soft side of the velcro to secure the battery in the tray.
Wedge the remaining connector in between the battery and the strap.
Ensure that the loop around the left standoff is slid up to rest in the center of the standoff, so that the strap stays in place for the duration of the flight. The strap should go evenly across and be firmly pressed against the battery.

Charging a LiHV battery on LiPo setting will likely not cause a fire but will not allow a full charge, and can damage the battery. Charging a LiPo battery on LiHV settings can cause a fire. Please be aware of this. |

What is the different between fast charge, balance balanced charge and storage charge settings on my charger?
Fast Charge - This mode tells directs the charger to only complete the first charging phase, constant current (CC) charging. The charger applies a high enough voltage to cause current to flow into the packbattery, up to the max current you've set. This gets the pack mostly charged, but the battery can still take more.Balance will mostly charge the battery, but there will still be some unused capacity with this mode.
Balanced Charge - For maximum health, you should always balance charge your batteries. This is also why your battery has a second plug on it. This second plug is called the balance plug “balance plug” and is used by your charger to individually monitor and balance charge each cell.
Storage Charge - This option should be used if you are not planning on using your battery for an extended period of time. You should never store a fully-charged LiHv LiHV battery. Instead, it should be set to the storage charge setting, and brought down the voltage decreased to “storage voltage”, which is 3.8 to 3.85 volts per cell. You will receive a beep and finish will be displayed when the LiHv battery has been fully stored.
If I plug my battery in and the charger instantly beeps instantly with an error preventing charging , what should I do?
Check that your the balancer plug (white plastic plug on the battery) is plugged into the charger’s balance port correctly. Check that your and the XT90 plug is are properly plugged in. Wires on both ports (balancer and XT90) should be plugged in tight and not feel loosetightly.
Check Verify that you have the correct charging mode set on the charger to charge the battery.
If all of these options look fineare not the issue, use the battery cell option on your charger to make sure all cells are balanced. You can check the cells by pressing the stop button once, the start button once, and then the up arrow once. If you see a damaged cell, replace the battery immediately.
What setting should my charger be set on when charging my 25,000 mAh battery?
You should always charge Lithium High Voltage batteries on the LiHV setting on your battery charger. Failure to charge a High Voltage battery on the LiHV setting can cause damage to the battery and also cause a fire hazard. If a LiHV battery is charged on the LiPo setting and not LiHv, your battery will not meet maximum charge, even if the charger says it is finished charging.

Charging a LiHv battery on LiPo setting will likely not cause a fire but will not allow a full charge. Charging a LiPo battery on LiHv settings can cause a fire. Please be aware of this. |

Can I still fly and use a battery if that battery is damaged?
NEVER fly with a damaged battery. Even if it is minimal damage. This can cause your drone to fly unsafely and crash. Replace the battery and safely dispose of the damaged battery.Can I still fly using a damaged battery?
