Ok I am looking at how I am going to charge my 13Ah hawkers. I currently have 2 500mA chargers which are great if I have a couple of days to spare but I want to be able to charge them quicker.
What are the potential problems of using a bench top power supply unit?
Where is the best/cheapest place to get a decent charger?
Tried Technobots?
Providing the supply is constant voltage you shouldnt have a problem... From what I know the hawkers are very good with charging and can be constant current charged too.
Long as you dont go above 14.8v, or you start to harm the hawkers.
Mr Stu
i have looked at technobots but sadly i dont have that much cash spare at the mo!
I would be getting a variable supply so i can set it properly. Correct me if im wrong but the charging voltage should be 13.8v?
13.8v is for maintenance charge (trickle charge)
14.2v for bulk charge. (80%)
we charge ours with a 40A power supply at 14.7v and turn it off when the current drops to 1Amp.
I charge mine with an Wheelchair charger.
Alan, I take it that the 40A power supply you are refering to is the one you can buy from technobots?
yup
I have a DC powersupply of 44.7V capable of supplying 11 Amps. Did a wonderfull job on the Hawker Cyclons (18 cells 8Ah)in TAN.
Now just standing in a shelve as we went to the 9Ah 12V PBQ batteries,a lot cheaper.

i use the zafire 90 for batteries from 1.2-90 Ah charge current: 0.5A and 3.3A. price $55
klick for chargers and select type and check the tecnical data
