but the best value for your money...so far..
had two 12amps continious and currently using a 15amps with another 24amps PSU on the bench.
resistors are easier to mount and better than using fans but would need much ventilation and cooling down. i personally lean on using a lightbulb cos it does not need that much cooling down. i just made sure its mounted next to the exhaust fan.
info are available to those interested....did more testing today...the 15amp unit can charge one pack at 4.5amp, run my robitronic dyno at 7volts 11amps(15sec intervals),and charge my radio pack at 12v 2amps all in one go....
