West Mountain Radio 58250-1015 CBA Computerised Battery Analyser User Manual
Introduction
Thank you for choosing the West Mountain Radio CBA. It takes the guesswork out of using batteries and it will help you learn about batteries.The CBA is much more than a simple battery voltage tester or a battery load tester.The CBA will test virtually any type or size of battery, any chemistry or number of cells, with modest limits on voltage and discharge current. Now anyone can do scientific tests of their batteries for a reasonable price. The CBA V is capable of tests up to a maximum of either 40 ams at lower voltages or 150 watts continuous at higher voltages. When using an optional amplifier, tests can be done at 500 watts. Amplifiers can be used in parallel for higher power discharges.The CBA not only tests the total amount of energy stored in battery (capacity in amp-hours) but it graphically displays and charts the voltage versus time using a constant current load. Graphs may be displayed, saved and printed and the axis parameters can be changed at anytime. Multiple test graphs of the same battery, or multiple batteries, may be compared or overlaid; a very useful feature.The CBA is ruggedly built and supplied with 45 Amp Powerpole® connectors for the battery connection. It is small with a high performance cooling system and quiet fan. It is provided with LED indicators, visible from across a room, that display communication and test status.The software supplied with the CBA, is easy to use and intuitive. It provides automatic sensing of the battery cell count, a safety check of the test rate, and recommends a minimum safe discharge voltage. It is designed to protect both the CBA and the batteries being tested. Test profiles may be edited or recalled by the user.The optional Extended Software license provides all the features of the standard version, but adds a number of advanced features. The Extended Software version also adds the ability to graph the battery temperature with when the optional temp probe is connected.

Safety Precautions
The West Mountain Radio CBA is inherently safe but the batteries it tests are not. Anything that stores energy is potentially dangerous! Some types of batteries are safer than others but they are all capable of causing explosions or fires.For technical information on a battery, refer to the Battery Manufacturers website to get detailed information on the rating of the battery. Most battery labels have limited information, but the manufacturer’s website may have more detailed information.General Information on batteries is also available on the West Mountain Radio CD.
Primary Safety Considerations:
- Never discharge a battery at a higher discharge rate than it is designed for.
- Never use a battery that has poorly insulated or frayed wiring or exposed metal parts.
- Never connect a battery with reverse polarity.
- Never test a battery near flammable materials.
- Never allow a battery reach a temperature that causes it to get so hot that it may be too hot to touch, or battery case softens or fumes.
- Recharge the batteries immediately with an appropriate battery charger after the test is complete. Some types do not like to sit discharged for extended periods of time.
- Never test or charge your batteries while unattended.
- Have a fire extinguisher nearby.
- Never connect a battery with the polarity reversed!
- Always connect the USB cable BEFORE connecting the battery!
- Do not connect a battery to the CBA that is connected to something else unless an isolated USB hub is used.
- If using a USB HUB, make sure it is a powered hub. That means it will have a separate power connection to the hub so it can fully power the CBA.
- Operate the CBA in a cool dry location.
- Never allow fingers, metal parts or wiring of the battery come in contact with the metal heat sink.
- Never allow the cooling fan to be blocked or jammed.
- Do not ignore the warnings that the software may report.
- The CBA can get hot. Do not touch the metal heat sink while, or shortly after, conducting a high power test.

Lead Acid Battery Safety Warnings:These batteries, especially automotive and marine types, give off explosive hydrogen gas when charged. A nearby or internal spark or flame can cause a lead acid battery to explode sending liquid acid and lead shrapnel in all directions. This is particularly dangerous and frequently causes blindness or severe scarring injuries.Never use a standard lead acid battery in a non-ventilated container. Sealed lead acid batteries such as gelled or AGM (absorbed glass mat) types are much safer.Never make the last connection to a lead acid battery causing a spark on the terminal. Always connect the load or charger last, and at a safe distance away from the battery.
NiCad, NiMh, and Alkaline Safety Warnings:These batteries can be dangerous also. If they are shorted out, or charged or discharged at too high a rate, they can overheat and explode. A single D size NiCad cell can actually melt a 10 penny nail; DO NOT TRY THIS!
Lithium Safety Warnings:Reprinted with permission of the Academy of Model AeronauticsWords in bold and ( ) were added by West Mountain Radio
Lithium Battery FiresLithium batteries are becoming very popular for powering the control and power systems in our models. This is true because of their very high energy density (amp-hrs/wt. ratio) compared to NiCads or other batteries. High energy comes with increased risk in their use. The, principal, risk is FIRE which can result from improper charging, crash damage, or shorting the batteries. All vendors of these batteries warn their customers of this danger and recommend extreme caution in their use. In spite of this many fires have occurred as a result of the use of Lithium Polymer batteries, resulting in loss of models, automobiles, and other property. Homes and garages and workshops have also burned. A lithium battery fire is very hot (several thousand degrees) and is an excellent initiator for ancillary (resulting) fires. Fire occurs due to contact between Lithium and oxygen in the air. It does not need any other source of ignition, or fuel to start, and burns almost explosively.
These batteries must be used in a manner that precludes ancillary fire. The following is recommended:
- Store, and charge (discharge), in a fireproof container; never in your model.
- Charge (discharge), in a protected area devoid of combustibles. Always stand watch over the charging (discharging), process. Never leave the charging process unattended.
- In the event of damage from crashes, etc, carefully remove to a safe place for at least a half hour to observe. Physically damaged cells could erupt into flame, and, after sufficient time to ensure safety, should be discarded in accordance with the instructions which came with the batteries. Never attempt to charge (discharge) a cell with physical damage, regardless of how slight.
- Always use chargers designed for the specific purpose, preferably having a fixed setting for your particular pack. Many fires occur in using selectable/ adjustable chargers improperly set. Never attempt to charge Lithium cells with a charger which is not specifically designed for charging Lithium cells.Never use chargers designed for Nickel Cadmium batteries.
- Use charging systems that monitor and control the charge state of each cell in the pack. Unbalanced cells can lead to disaster if it permits overcharge of a single cell in the pack. If the batteries show any sign of swelling, discontinue charging, and remove them to a safe place outside as they could erupt into flames.
- Most important: NEVER PLUG IN A BATTERY AND LEAVE IT TO CHARGE (DISCHARGE), UNATTENDED OVERNIGHT. Serious fires have resulted from this practice.
- Do not attempt to make your own battery packs from individual cells. These batteries CANNOT be handled and charged casually such as has been the practice for years with other types of batteries. The consequence of this practice can be very serious resulting in major property damage and/ or personal harm.
The CBA is been supplied with a 25 amp fuse installed to give better protection from an inadvertent reverse polarity connection, shorting the heat sink to the battery or having external connections that cause ground loop shorts. A fuse is partial protection, as the 25 amp fuse usually blows before damaging the internal electronics. It depends on the voltage and source impedance but ultimately time. Included is a spare 25 amp fuse packed separately.
The CBA V can be used with a 40 amp fuse for larger discharges in accordance with the specifications. Do not use the 40 Amp fuse unless planning to test a battery in excess of 25 amps discharge. At higher voltages 25 amp is the most the CBA can handle. It can handle up to a 40 amp discharge at 1.5 volts.
CBA V Connections
USB Port
This is the connection to a PC for power and data. Make sure the PC is set to never power down the USB port, so tests are not interrupted.
Accessory Port
This port is for future CBA modules or for the stand-alone temperature probe.If using the remote voltage sense cable, it includes the temperature probe. Do not use the stand-alone probe if using the remote sensing cable. With the standard software, the temperature probe is used to abort a test if the battery gets too hot. With Extended software the temperature can be graphed with the voltage on the screen. Notice from the above diagram the two pins that need to be used for the stand-alone probe.
Remote Sense
This is an optional cable to separately detect the battery voltage. When running a high current discharge test, there is a resistance across the cable. That means the voltage at the battery is not the same as the voltage at the CBA. The remote sense cable will allow the CBA to read the actual battery voltage. This is important for the exact test termination time. The remote sense cable also has a temperature sensor that can be attached to the outside of the battery to terminate a test in case of over heat. The Extended software also allows for charting the temperature.

FuseTo protect the CBA, use the smallest fuse necessary. This is a standard ATC automotive fuse. A fuse puller was included with the CBA.
Battery ConnectorThe connector is a 45 amp Anderson Powerpole connector. A pigtail adaptor is included with the CBA to help interfacing to a battery. The West Mountain Radio website has numerous pre-made cables to go from this connector to other connector types. This includes a laptop battery connector and adaptors for cylindrial cells. For odd sized batteries, consider making an adaptor from an old charger.
Set-up & Installation
Perform the following steps for software installation and hardware set-up:
- Insert CD into drive. If the auto-run does not start, browse the CD and double-click the set-up program. Make sure this is done as an Administrator.
- Connect the CBA to the PC USB port using the supplied USB cable before connecting a battery. At this ponit, the Green LED should be flashing on the CBA. If it is not, the drivers may not have installed correctly.
- Start the West Mountain Radio CBA Standard software. At this point, the Green LED should be solid green, indicating the software is in communication with the CBA V.
- If Extended software was purchased, click on TOOLS>CBA DEVICE. Then click on the CBA the Extended license is for and click on LICENSE. Enter the user’s name and key exactly as supplied by West Mountain Radio.
- Connect a battery (or power supply) for testing, making sure the polarity is correct.WARNING: BE CERTAIN THAT YOU HAVE THE POLARITY CORRECT! FOR STANDARD CONVENTION: PLUS TO PLUS, MINUS TO MINUS and RED TO PLUS, BLACK TO MINUS!
- In the software, click on TEST, then NEW TEST.
- To start a typical test, click on the DISCHARGE icon on the left side of the screen and fill in the information about the battery. Most important is to enter a minimum cut-off voltage (such as 10.5V on a 12V battery) and a discharge rate. Click on SUGGEST for further assitance.
- Click on START to begin testing.
- The test will continue until the test “Cutoff V” is reached. At that point the test will automatically stop and the program will beep and display “Test Complete”. Everything will return to the stopped condition ready for another test or to save the file. Disconnect the battery at this time.WARNING: DO NOT LEAVE A BATTERY CONNECTED AFTER TEST COMPLETES! LEAVING A BATTERY IN A DISCHARGED STATE FOR PROLONGED PERIOD OF TIME COULD OVER DISCHARGE AND DAMAGE THE BATTERY.
Caution: This battery and the CBA may be HOT!
