DescriptionA CBA alone is all a hobbyist would need to determine more than they would ever need to know about batteries. Virtually
any battery’s capacity may be measured and compared. A CBA may be used to measure internal resistance of a pack and with
simple calculations determine what the battery will do at high currents without taking a chance of damaging a pack, however
commercial users and battery suppliers may need to test at high discharge rates.
The CBA amplifier is an add-on accessory for a CBA designed primarily for commercial users or that must test smaller
batteries at or near the destructive limits. It also may be used for testing large lead acid batteries used in power
backup applications and for FAA aircraft battery test requirements. Competition modelers may wish to have and amplifier
for high rate testing.
The amplifier is a very simple in concept. It is a DC amplifier that connects to a CBA and amplifies and regulates
discharge current of the CBA times 10. It increases the 100 watt continuous capability of the CBA to 500 watts! It will
allow testing of a single nickel cell at 160 amps and regulate that current all the way down to .9 volts. A single Lithium
cell may be tested at 120 amps!
If you have a need for high rate testing up to 160 amps or 500 watts, whichever is higher. You may add a CBA amplifier
to a CBA for a laboratory battery test system at the fraction of the cost of comparable lab equipment. In lab or production
use you will find the ease of use is a big time saver compared to complicated and expensive test equipment.
Test at 10X current with a CBA amplifier in between a CBA and your battery.
A special version of the CBA software is downloadable o do the proper 10X calculations with one or two amplifiers.
Perform tests quickly at or near destructive limits; up to 500 watts or 160 amps maximum, whichever is higher!
High voltage testing at up to 48 volts; the equivalent of 1 to 38 NiCad or NiMh cells.
Test any type of battery: NiCad, NiMH, Lead Acid, Li Ion, Li Poly, Alkaline, Carbon Zinc, Mercury etc; from coin
cell to automotive or larger.
Superior constant current testing ,electronically regulated amplification, using an amplifed six FET electronic load.
Automatic fan operation whenever current is sensed from the CBA with a cool down cycle.
May be left in line and switched off for normal CBA operation at lower discharge rates.
Supplied with copper bus 5/16 bronze bolt battery connections and plug in Powerpole CBA connector.
Discharge current with amplifier on 10 to 160 Amps.
With two CBA amplifiers connnected with our 1000 watt power harness you can run tests at double the ratings of a
single amp.
