October 26th, 2012 05:54 PM #11what you need is a SWITCHING POWER SUPPLY... those being used in CCTV system.. its regulated 12V up to 30 amps.. you can also combine 2 power supply to make it 60 amps..
you can buy that at around 2,500 petot each.. they can drive your amps without draining the battery plus its regulated so you will not hear noise

October 27th, 2012 03:21 PM #13Hindi problem ang charging current sa car battery unless low charge na ito. Ang problem ay dapat increase yun dc output into 14.5V same as alternator charging voltage. Dapat dagdagan ang winding +12v secondary winding. Pero mahirap magsiksik ng extra winding sa ferrite transformer. Hindi mo naman pwede tangalin yun +5V winding dahil kailangan ito ng referance for overvoltage control ng pwm ic.

malay mo naman shoe brush ang toothbrush nya
kahit trickle charger di pwede ang comp power supply, sinabi na nga na 12 volts lang ang output nyan e, too low to push any charge to a lead acid battery. kung pwepwede yan e di sana nauna na ako gumawa nyan, sa tanda kong ito ba. ka-mura ng battery charger eh, may trickle charge function pa at siguradong hindi ma-overcharge ang battery mo.
