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.
