1. Product description
The c-Go Battery Test System from IVRA Electronics will make 12V and 24V battery testing and/or
reconditioning easy and efficient. Normal battery testing will be easy using our intuitive menu and 7”
touchscreen. Connect the batteries and temperature sensor, set the right testing parameters and
press start is all you have to do. The Battery Test system will test lead-acid(Gel /AGM) and lithium ion
batteries and show a detailed report on the 7” touchscreen when the test is finished. An option is to
write the result to a flash drive. Another feature of the battery test system is testing 12V and 24V
chargers.
Potential applications
-Battery quality control
-Reconditioning batteries
-Checking batteries so they can be redeployed
The BTS consists of:
1. A high quality metal powder coated housing.
2. A 7 inch touch display.
3. Two or four battery test channels.
4. Up to three built in chargers (12V or 24V or 12V-24V combination).
5. One built in discharge module.
6. Two or four SB50 to Crocodile clamps battery test leads.
7. Two or four temperature sensors with 3.5mm jack cable.
8. One power cord IEC-C13.
9. SB50 to XLR charger test lead.
10. USB –3.5mm jack serial cable.

Symbols:
You must obey the safety instructions.
Read the user instruction before use
For indoor use only
Do not use in a damp environment or in rain.
Do not dispose of the BTS as household garbage.
In order to save the environment it must be disposed of with care in
accordance with local regulations.
The BTS meets the CE requirements valid in Europe.
2. Safety instructions
-Do not charge the Li-ion battery at temperatures below 0°C. First transport the Li-ion battery
and the BTS to a location where the temperature is higher and then start the test/charging
procedure.
-Charge specified batteries only. Do not recharge non-rechargeable batteries.
-Charge the batteries only if there is proper ventilation. Especially around the batteries. While
charging, a small amount of explosive gasses can be generated in the batteries.
inadequate ventilation in combination with open fire or sparks can lead to dangerous situations.
-Do not connect or disconnect the battery while the BTS is testing the battery. E.g. to reduce risk
of sparking.
-Batteries are capable of providing a lot of energy in a short time span. Prevent short circuits in
any way. For example walking over the cables or damaging the cables or connector by improper
use.
-Only use cables supplied with the BTS.
-Do not use the BTS if the cables are damaged.
-If the power cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard. If the BTS is defective, do not try to repair
it.
-The BTS should never be used in a very damp or wet environment (for instance outdoors), never
poor fluids over it or submerge it in water.
-The system must not be exposed to chemical substances or vapours.
-Make sure the BTS is positioned stable.
-Keep a free zone of 20cm around the BTS to ensure that heat, generated during operation, can
be removed.
-Do not place the BTS in direct sunlight.
-Do no place the BTS in an environment that contains mechanical vibrations(i.e. Compressors,
etc.) or where a lot of heat is generated(Heaters, Ovens, etc.).
-The ventilation slots of the BTS have to be kept free of excessive dust built up.
-Make sure the BTS is connected to an appropriately earthed wall outlet.

Power on battery test system using the power switch on the power entry connector after the power
cord is connected.
Connect all battery cables to the inputs and the temperature sensor cables to the temperature
sensor inputs.
5. Language selection

6. Battery test
6.1. Connect battery
Mount the battery sensor to the minus pole and connect the crocodile clamps to the battery.
The battery cable and the battery sensor cable must have been connected to the same channel
number.
6.2. Steps to start a battery test
1. Select the channel to which the battery has been connected

English
9
2. Enter the battery parameters:
a. Select the battery type.
b. Enter the C5 capacity. (The C5 capacity is the specified capacity for a 5 hours
discharge.)
c. Description is optional, but useful in the list of results.
d. When a battery has not been charged properly, it can be worthwhile to recondition
the battery by increasing the discharge/charge cycles. If you do not wish to
recondition the battery you can leave the default option to 1.
The voltage 12V/24V is automatically detected. 24V batteries can only be tested if the BTS
has also a 24V charger inside (Option for 4-channel model only).
A set of two 12V batteries in series must be split and the 12V batteries must be tested
separately because their capacities may differ.
Usually only 24V Lithium ion battery packs are tested as 24V batteries.

3. Start the test by the button “Test battery channel x”

English

4. During the test, the status of the test is shown (in this example channel 2 is shown):
a. Charge phase. This can be one of:
i. Stand by
ii. Waiting for internal device. (The internal discharge unit is shared over all
battery channels and in the 4 channel model there are less chargers than
channels. Thus it can occur that a battery must wait for a charger or for the
discharge unit.)
iii. Charging
iv. Discharging
v. Ready
vi. Testing external charger
b. Actual battery voltage
c. Actual battery current
d. Discharge capacity compensated for temperature. (Between brackets is the capacity
uncompensated for temperature.) These values are percentages of the C5 capacity.
e. Actual battery temperature
f. Actual discharge or charge cycle elapsed time
g. Total elapsed time
The two graphs show the battery current (red line) and the battery voltage (blue line)
during the test.
If the test is ready, the “Stop channel x” button has to be used before another battery can be
tested. This button might also be used to abort a running test.

5. To observe the list of results, press the Results button
The result list is shown as in this example:
At the left part of the screen, the list of results comprehends:
a. Red triangle in case the result has an error
b. Result sequence number
c. Channel number
d. Battery type
e. Battery C5 capacity

English
13
f. Discharge capacity compensated for temperature. This value is a percentage of the
C5 capacity. If more than 1 discharge has been performed, all results are listed. F.e.
88%/89%/89%
g. Elapsed time
h. Status (completed or not)
i. Description
In case the test was a charger test the items d. e. f. are replaced by “Charger test” and the
charger current and voltage during the test.
Another result can be selected by touching it.
At the right part of the screen the selected result is showed in more detail: Uncompensated
capacity, average temperature during test and error description are additionally shown.
In case a flash drive (FAT32 format) is present:
The button can be used to store the selected result (same information as
on screen) to the flash drive.
The button can be used to store all results (same information as on the list
on screen) to the flash drive.
The information is stored on the flash drive as an ASCII text file.
The button “Clear all results”, will clear the complete result list. However the running tests
(not yet in this list) are unaffected. This cannot be undone.

7. Charger test
The BTS can test both 12V and 24V chargers. Even if the BTS has no internal 24V charger.
7.1. Connect charger
If the charger has no XLR connector:
Connect the plus and minus cables of the charger to the crocodile clamps of the BTS
cable.
If the charger has an XLR connector:
Connect the SB50-XLR cable to one of the channels of the BTS instead of the cable
with crocodile clamps. Connect the charger to the XLR cable.
Switch on the charger.
7.2. Steps to start a charger test
1. Select the appropriate channel and press the yellow “Test 12V charger channel x” or “Test
24V charger channel x” button. Be sure to select the right voltage.
2. After 2 minutes the test is finished. The result can be viewed in the same way as the battery
results.

8. BTS - PC connection
A USB –3.5mm jack serial cable is included to connect the BTS to a PC or laptop.
In this way it is possible to transmit the following information from the BTS to PC/laptop:
-Real time data for each channel: voltage, current, temperature, status
-Results
This cable can also be used for software update of the BTS.
9. BTS advanced
In the hardware overview screen the actual switches and measurements for the internal chargers
and load can be observed:
If the charge/discharge cables have been removed and the voltages in the main menu are not 0V, the
button “Calibrate SB50 @0V” can be used to calibrate the voltage offsets.
