More "juice" for the Turbo Express - Lithium Ion mod

[Duo_R]

Will do, here are the batteries I used:

I will put together a tutorial on how to wire up / charge etc.

Please share whatever you come up with. recharchables are ok with me. but lipo would be better if i could work it into the system. I already have Thesteves screen mod and that alone as increased my battery life by atleast one hour. more would be icing on the cake.

Thanks duo

Made a battery pack, it's one piece now:




And after a little dremel work it has a stock fit now:





Will add a charging port, battery will need to be removed to charge (similar to my old Gameboy Advance chargepack). Charging port wont be visible externaly. Also a quick disconnect will be added so battery can be removed when charging. I just need to get more battery covers now!

I'm really wanting a lowdown on total battery life on this after the mod is done. This is really slick.

lol that is a 2000mAh battery.
my NiMh are 2300mAh and should give about 1 more hour then your LI battery.

[HercTNT]

my interest comes from the fact that i need 6 batteries for my gt, but my charger can only handle 4 at a time. Obviously the immediate solution would be to get a better charger. there is something sexy though about a removable battery pack.

[thesteve]

i just have multiple chargers.
the beauty of LI is the charge rate.
those can be charged fast.

yea i got the same energizers you do and it takes 8 hours. not to bad if i pop them in over night. I"m currently using 8 batteries though in between three machines. i have my gameaxe, a game gear, and my gt. according to sanyo, nimh batteries can be rapid charged but it lowers there mAh rating. the eneloops say not to rapid charge them at all.

12 batterys 3 chargers 2 or 3 expresses 0 or 1 gamegear

it is actually a 2200mah...so that's pretty close man.

That's the beauty of these batteries, I can fully charge in about 3 hours. The pack is all set, she is charging right now and going to do bench test with a stock screen later today.

I have an assload of Eneloops too - because they retain their charge so well, I can stuff 6 of them in the GT, and cycle them easy.  I use them in the Wii, my wireless keyboard, Nomad, GT Gameboys, yada yada yada

[HercTNT]

eventually i will upgrade to eneloops.

Battery in testing: stock screen with Li-ion

[Duo_R]

Ok got just over 5 hours gametime on stock screen. A more energy efficient screen the like the one that TheSteve installs should add a few more hours to that hopefully bringing 7-8 hours game time.

Here is a fun little time lapse video:

wow, my energizers give me about 4 and a half hours and i need 6 of them. So duo, when you wanna do this mod for me ?
