Battery Requirements

Using One Battery

The PowerSafe receiver 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 ﬂ ight. 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 receiver offers a true redundant dual battery system. When us-

ing 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.

It’s normal for one battery to discharge slightly more than the other. This is the

nature of a 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.

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. 12- and 24-inch EC3 battery extensions are available for installations

where the battery is located a distance from the main unit.

Using Dual Voltage Regulators

Spektrum offers a 7.5 amp (11-amp peak) 6.0 volt regulator (SPMVR6007)

speciﬁ cally designed for use with the AR12120 PowerSafe receiver.

IMPORTANT: When using two batteries powered through two regulators, each

regulator operates independently. 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 makes it very

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

recommended 1-amp load before each ﬂ ight, monitoring the voltage of each

pack and recharging when the weakest pack reaches 40% capacity (see Battery

Capacity below).

Battery Capacity

Select a battery (or batteries) that has more than adequate capacity to provide the

necessary ﬂ ight time. Current draws may vary depending on your servos, installa-

tion and ﬂ ying style.
