I installed all 3 of the Spongeface kits (which are absolutely amazing) and have removed all the original electronics.
Sound blaster, wand kit, pack light kit. Nothing else.
Used a blue brick 12v 9800 mAh battery from ebay
I charged the battery for 3 days with the switch on, uninterrupted. When I plug it into the pack, the pack lights work in what I believe are an idle mode, but zero sound, and no response from the switches or button.
Thinking I hadn't charged it enough, I plugged it back into the charger. Out of curiosity, I tried turning on the pack while it was charging, and it worked perfectly. All the lights, sounds, functions doing what they should. OK, the battery just needs more juice. So I left it charging another day unplugged from the pack. Still no go. So I contacted the seller on the battery, and they quickly sent me a new one figuring I got a dud. Went through the same exact process with the new battery, with the same exact results. Then I discovered something odd. If I have the battery plugged into the charger, I can turn the pack on with full function, and it will keep working even if I unplug it. But if I turn it off, it will not restart without being plugged in.
I have since tried leaving both batteries charge for over 4 days, not plugged into the pack, with power switches on. I installed an inline power switch between the battery and electronics. Tried adjusting volume all the way low before start up. Nothing makes any difference. I get the cyclotron lights, and the powercell light. No sound, no function from buttons.
Only thing I can figure is there is just not enough power to "start" the pack.
Are my ebay blue bricks junk? Is the GB Fans brick of the exact same specs/shape/picture somehow different?
Is there a different battery I should consider?
Is there some other reason for the need to "jump start" my system?
Thank you for any points in the right direction. Very stumped.
