Q: Can I leave the battery
continuously on the charger?
A:
Yes, the charger will go into
"maintenance mode" and keep the battery
topped off.
Q: Can I draw power
from the battery when the charger is
connected?
A: Probably. . .
There is some pulsing going on with the
charger which your equipment might not
be happy with (it is a pulse-charger, 1
second pulses with 20mS gaps), but if
you combine this with the battery the
battery will fill in the gaps, so the
ripple is no more than it would see in
an automotive application.
Q: If
I discharge the battery while the
charger is attached will the charger
maintain a full charge?
A: Yes,
When the charger detects that the
battery voltage has dropped it knows
that the battery needs to be charged
and goes into "bulk charge" mode again
automatically.
Q: Can the charger
be left connected to the battery when
the charger is not turned on, or when
the input voltage of the charger has
been cut off?
A: Yes.
Q:
Can the charger be adjusted to lower
currents?
A: Yes. There are two trimpots
that we can adjust here or click here to view the instructions
Applications:
Charging wheel chairs, bicycles, and
scooters in a car, van or bus.
Microprocessor controlled 4 stage
adaptive charging algorithm suitable
for Gel, Absorbed Glass Mat, VRLA, or
flooded lead acid batteries.
Fully automatic without
intervention.
Output short circuit and battery
polarity protections. Input low voltage
and high voltage connections.
Charging
24 volt batteries from a
vehicle.
Charging
24 volt "jump start" batteries from a
12 volt tow truck or service
vehicle.
Charging
24 volt electric bicycle from a
vehicle.
Four stage charge--constant current,
constant voltage, fill, and float. This
charges your battery the fastest way
possible without damaging the battery.
It is suitable for any size 24 volt
lead acid battery.
Charge efficiency is 95% for the a
SLA, VRLA, or Gel Cell battery and 85%
for the charger, making a combined
efficiency of 81%. So a 12 volt 100 AH
battery would be able to charge a 24
volt 10 AH battery 4 or 5 times before
the host battery needs
recharging.
Installation
Notes:
- A qualified automotive electrical
technician should be used to wire the
charger into the vehicle.
- The BC-1224-10 converts 12 volt
power into 24 volt power, so for a 5
amp output the input needs over 10
amps. Make sure that the wires
connecting the BC-1224-10 are adequate
for the current and the length of the
run. If the voltage drop in the wires
are too much the "Low Battery Voltage"
alarm will come on. Wires that are too
small may also overheat and melt the
insulation, causing a dangerous
situation. 12 gauge is usually adequate
for runs up to 20 feet of wire (adding
together the positive and negative wire
lengths).
- PowerStream can supply the
connector that fits into many
wheelchairs (
we have the 3 pin
XLR style in stock
). Consult the manufacturer or a wheel
chair technician to obtain the proper
cable and plug. (If you know about such
things please educate us!)
- Try to connect or disconnect the
battery when the charger power is "on."
It is possible but extremely rare for
the charger to go into a fault mode if
the battery is connected first, but
cycling the power switch will clear
this "false fault."
- It is OK to leave the unit on the
charger when the power to the charger
goes on and off.
- Mount the BC-1224-10 in an area
that will get adequate ventilation and
will be free from rain, spray, or
excessive dust.
