To prolong the health of RC batteries,
you need to balance charge them correctly and discharge them properly
too. That means not leaving unused batteries fully charged, but
discharging them to their storage voltage. That is where this device
comes in handy. The BD200 is powerful battery discharging device. While
most good battery chargers have a discharge function, they are more
suited to charging batteries so their discharge rates tend to be just a
couple of amps at best; anymore and they would overheat. If you are
using high capacity, high voltage batteries this means discharging can
take forever. Not so with the BD200, with its mighty cooling fan it can
discharge a battery at up to 30 amps or 200 watts continuously, saving
you time and not putting stress on the electronics of your charger. Now
you have no excuse for not storage charging your LiPo batteries!
The BD200 is great at discharging
batteries, but it’s equally a really useful bit of test equipment for
measuring battery capacity and running load tests. It can be control via
its rotary dial, or through a PC application. If you operate it via a
computer, you can graphically log the discharge curve of the battery.
This can allow you to do useful things like helping you to compare
performance and health of different batteries.
The discharger is compatible with any
battery chemistry down to a minimum voltage of 5.4v and up to 35volts -
which is equivalent to an 8S LiPo. The unit is also self-powered from
your battery, so you can use it anywhere.
