Battery Requirements

Using One Battery

he 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.

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” 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 AR9100 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. (See Battery Capacity pg. 5)
