Battery Requirements

Using One Battery
The PowerSafe allows the option of using one or two battery packs. When

using one battery simply plug the battery into either one of the two battery

connectors (BATT 1 or BATT2). Be sure to secure the unused battery

connector. Note that the open contacts of the unused battery are not back

powered (not electrically hot), however, the unused connector should be

secured to prevent it from entangling during flight. When the system is

powered using one battery, a single blue LED will constantly emit when

the system is powered on.
Using Two Batteries
The PowerSafe offers a true redundant dual battery system. When using

two battery packs, each pack functions independently and is isolated from

the other, so that if one pack should fail (open circuit, short-circuit, or

become discharged), the other battery will provide power to operate

the system.
When using dual batteries, it’s important that both batteries be of the same

capacity and ideally of the same age and condition.
Note: It’s normal for one battery to discharge slightly more than the other. This is the

nature of a truly redundant isolated battery system. The battery that has the higher

voltage or lower internal resistance will discharge at a faster rate. Generally the

difference is negligible (less than 10%). Because of this it’s normal for only one blue

LED (Batt 1 or Batt 2) to be on when the system is not under a heavy current load

depending on which pack is providing more power.

When using two batteries, the total available capacity equals the sum total

of both batteries e.g., BATT1—2000mAh + BATT2- 2000mAh = a total

capacity of 4000mAh.
Note: 12- and 24-inch EC3 battery extensions are available for installations where the

battery is located a distance from the main PowerSafe unit.

Using Dual Voltage Regulators
Spektrum offers a 10-amp (16-amp peak) 6.0-volt regulator (SPMVR6010)

specifically designed for use with the AR12100 PowerSafe.
Important: When using two batteries powered through two regulators,

each regulator operates independently and it’s common for one battery

to be discharged at a slightly higher rate depending on the condition

of the battery (internal resistance, voltage, etc.) and the tolerance of the

regulators. This causes one battery to discharge before the other and it’s

important to check each battery using a loaded battery tester (HAN171) at

a recommended 1-amp load before each flight monitoring the voltage of

each pack and recharging when the weakest pack reaches 40% capacity.
