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.

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.
