iSDT BG-8S tester / balancer

BG-8S is a multifunctional measuring device enabling testing of the condition of battery packs of most main model types: Li-Po, Li-ion, LiFe, LiHV, NiCd and NiMH. It also allows autonomous balancing of lithium sets to balance the voltage of individual cells to the same level. In the servo signal testing mode, it can be used to measure the parameters of the servo signal at the output of the receiver - PWM for classic servos and serial S.BUS. It can also function as an intelligent USB charger / power bank powered by a connected battery.

VOLTAGE TESTING OF LITHIUM BATTERIES

The device allows the measurement of 2-8S lithium batteries (Li-Po, Li-ion, LiFe, LiHV) without the need for additional power. To test 1S batteries, a power supply with a voltage higher than 5 V must be connected to the XT60i input socket. The tested battery is connected directly (sets with JST-XH service connectors) or using a suitable adapter.

The tester measures and displays:

• total battery voltage
• voltage of individual elements of the set
• the voltage difference of the cells with the highest and lowest voltages

VOLTAGE OF NiCd AND NiMH BATTERIES

When testing 4-10 art. NiCd and NiMH batteries do not require an additional power supply. To test NiCd and NiMH batteries with less than 4 cells, a power battery with a voltage higher than 5 V must be connected to the XT60i input socket.

The tester measures and displays:

• total battery voltage

BALANCER (2-8S)

The BG-8S enables autonomous balancing - the device discharges the cells of the set to the level of the cell with the lowest voltage (the device is powered by a discharged battery).

SERVO SIGNAL TESTER

To test the servo signal, the corresponding output (channel) or S.BUS socket of the receiver is connected to the BG-8S with a three-core servo cable in the standard connection so that the black (brown) wire (-) is connected to the tester / balancer socket (-). If the supply voltage of the receiver is lower than 5.0 V, an external power supply with a voltage of at least 5 V must be connected to the XT60i socket.

• Testing the PWM signal - width modulated signal for conventional servos: After connecting the signal output from the receiver for conventional servos (PWM), the BG-8S measures and displays the receiver supply voltage, repetition frequency and signal pulse width, which it also displays as relative deviation in%.
• Testing the S.Bus signal - serial signal for S.Bus servos: After connecting the serial S.BUS signal output from the BG-8S receiver, it displays the relative amount of deviation in% and as a bar graph in up to 18 channels.

USB CHARGER

The BG-8S can also serve as a "field" USB charger / power bank powered by a battery connected to the XT60i socket - this is protected by the tester from excessive discharge. The BG-8S allows charging of common devices (5V / max. 2A) as well as intelligent fast charging of devices using Qualcomm Quick Charge 2.0 / 3.0 technology, it is compatible with BC1.2 and Apple devices. Allows charging max. 12 V / 2 A.

Package includes: Tester BG-8S, screen protector, instructions.
