Zee100 · Post by **Zee100** » Mon Mar 27, 2006 2:46 pm

i was looking at the ratings of a ds battery compared to a psp battery, there pretty similair in the volt rating but the psp battery (the stock one) holds more than 2 times the MaH rating of the ds (stock) battery. the question i hav e is would it be posible to use a psp batery in a ds( changing some stuff obviosly would need to be done)

is it possible?

would it work?

would the ds be ably to charge it?(probably not)

thanks

The PSP voltage is 5v... How much is the DS battery?

5.2v I think?

The DS is 3.7v (one li-poly cell).
You'll need to build a stepdown DC-DC converter for that.

Damn, that's quite small. Does it use step-up tranformers like the PSOne screen to power the backlights?

the psone screen uses a cold cathode, which involves firing electricity though a near-vacuum. i think the ds uses some sort of electroluminescent stuff or something. low votlage.

The DS uses LED's, and a diffusion panel.

but the actual battery is 3.7 right? i think it uses one lithium cell, and i remember looking at my friends

Yes, well no...it's actually 3.6 Volts at 1800 mAh

only .1 volt diference,

that would probably work and almost triple your ds playing time

You would have to mod the battery slot tho......

or just use wires and tape the bat to the outside

would the ds be able to charge it? :
