series of rechargeable NiMH AA Battery as power source
« on: April 27, 2010, 02:53:01 PM »
may napanood ako minsan sa discovery channel about the Buckeye Bullet 1 setting world speed record on electric vehicles using series of rechargeable NiMH C Cell batteries ( check it out at http://en.wikipedia.org/wiki/Buckeye_Bullet   or http://www.speedace.info/osu_buckeye_bullet.htm  for more details).

pwede rin kayang gamitin ang series of rechargeable NiMH AA Battery as power source for 3 cfl, 1 radio, 1 20" tv, at 1 deskfan (hindi sabay-sabay gagamitin). brownout kasi lagi ngayon... mas mura kaya kaysa gagamit ka ng automotive battery?

marami kasi akong recargeable NiMH batteries na ginanagamit ko sa photography.

need fresh ideas....kung hindi siya feasible gamitin dun sa mga electrical appliances/units na nasabi ko saan kaya pwedeng i-apply?

mas mura pa sir gumamit ng SLA at inverter. mababa rin ang AH rating ng mga NiMH na AA battery kaya kailangan pa mag-parallel.

NiMH or Lithium ang ginagamit sa EV's dahil magaan sila.

pwedeng gamitin sir sa multiple LED light na flashlight. though medyo mura na rin 'yung may kasamang SLA, 700 PhP 'yung merong 36 na white LED. medyo maliwanag na rin.

ok rin ba ung ggawa na lang ako ng led white lights na magrereplace sa mga cfl in case na brownout at d2 sa series of rechargeable AA batteries ko ikakabit para kahit ilaw eh meron ako kapag brownout....

ilang white LED kya ang pweden tumumbas sa mga 18Watts na CFL at ilang minuto kaya ang itatagal gamit ang mga AA batteries?

or pwede rin kayang white LED na rin ang gamitin kong replacement sa CFL, sa AC ko na rin ikabit pra makatipid ng kuryente?

ilang watts ba bwat isang white LED?

sa ACE meron sis.

kung 'yung ordinary white LED's, 100's ang katumbas ng isang CFL.

rdpzycho, ask ko lang kung ilang watts ang klalabasan ng 100 ng White LEDs? ilan din ang required voltage nito?

depende sa LED. hindi ko alam kung ano lumen output ng standard white LED. pero merong mga 100 lumens+ na LED, halos 2W na CFL ang equivalent noon.
