What components do I need to produce my 3 rechargeable Power-Packs using what ive collected so far ? Please can anyone help ?

Hello & Good day to you all,

I'm making my own powerpacks for: a miniature wireless CCTV camera & receiver (Link Below for specs) , and a rechargeable powerpack to charge my laptop (that dies in 15minutes!)

Wireless Pinhole Spy Camera & receiver

After spending stupid money on sh*t 9 volt batteries (600mAh = £11 EACH) - ive had enough of the crap and absolutely absurdly LOW capacity 9 volt batteries out there (when TODAY's 'D' cell is capable of 11,000mAh !!!) and extremely high cost - i am making a battery-pack to power my receiver and another power-pack for the wireless camera using Ni-MH rechargeable batteries in the following packs:

Powerpack 1 (for camera) 6 x 18650 cells @ 3.6v each, 5000mAh {Total Power=21.6v}
Output Power Needed:  8v, 200mA

Powerpack 2 (for camera receiver) 24 x D Size cells @ 1.2v each 11000mAh ( Total Power= 28.8v)
 Output Power Needed: 12v, 500mA

 Powerpack 3 (for Laptop) 40 x D cells @ 1.2v each, 11000mAh {Total Power=48v}
Output Power Needed: 16v, 4A 


I should add that my existing 9-volt (2 new & 1 old) rechargeable batteries are a little-more-than USELESS (Rated @ 175mAh...{USELESS}) as the receiver of my wireless camera drinks the power (juice, lol) at an extremely FAST-Rate... 15 minutes of use and its DEAD. 10 mins of use from the old 9 volt battery. And thats all from a 9 hour charge... How pitiful...Despicable & Disgusting...

Now i got the idea to use a semiconductor from an instructable to make a simple solder-fume-extractor... (Link Below!) and also i know that resistors can reduce the voltage and amperage output of a circuit..........

Solder Fume Extractor


I have calculated, researched, 'Googled', calculated again, more googling and after 6 months of trawling through the internet to find parts of designs i could hack together to achieve my goals including getting answers from "SO-CALLED-EXPERTS 'In the trade'" and from Circuitry & Electronics Forums (whom shall not be named...) yet they always say, yeah, here's my email address, email me your questions and when i do, they all turn around and gimmi some crap like "oh...well...you have your plan all set-out so what do you need me for ?" AS*HOLES! F*C*ING AS*HOLES!!!
- If these peeps didnt want to help in the 1st place, then WHY BOTHER to give me their email address so i could ask them directly for help ? Im now going to give up and finally cry-out --- Please HELP (Again and probably for the last time!)
ok ok, enough of the hell's-anger-fuelled-rage-at-"EXPERTS" who give me the run-around.....(Bcoz they're AS*HOLES...)


Please please please can anyone help me find the components i need to make my very simple circuits for my battery packs !

I know that the use of a/a few? semiconductor/s (3 pin only) can let in a certain voltage and only output a specific voltage & amperage - i think i'll be needing a combination of a semiconductor and a resistor but i've searched continuous for 6 months now and am now irritated-beyond-belief that i still haven't found what im looking for or that no one is willing to help! ffs!

Many thanks in advance for some light on this darn-troubling matter....

Please Help !!!

Power-Specification For My Gear:

Wireless Receiver:
DC 12V 500mA

Wireless Camera:
DC 8V 200mA

Sony Vaio Laptop
16v, 4A

Also how do i charge my individual power-packs ? At what volts & amps do i charge them ??? Im already severely mobility-impaired and wouldn't want my life getting worse by any of my battery-packs exploding near me!!!! 

Ingredients i have collected So Far:
- 12 x 18650 5000mAh Batteries (Li-ion) (i want to make a total of two power-packs with these)
- Solder Tabs for battery Packs
-Small to medium collection of semiconductors + (plus) & - (minus) output voltages (from -24v to +25v) and from 100mA to 1.5mA amperage...
- Heatshrink (40mm, 50mm, 70mm)
- 24 x D cells @ 11000mAh
- 40 x D cells @ 11000mAh

I have no resistors but can order anything i need online if i only knew what to order!!!
i would also need to include a circuit to prevent deep-discharge & over-charge!

This is where i need the main help:

I cannot read electrical diagrams at all but try to but it takes a day of deciphering and thats only if i do it right, i have dyslexia and am fighting daily with it when it comes to referring to any diagrams concerning circuits so would it be possible if someone could draw the circuits i need onto an a4 piece of paper and photograph it to be posted here (or draw it in paint, lol) - what i mean is, to draw a basic 3 pin semiconductor (a square with the 3 pins coming out the bottom, lol) and then draw the wires that need to connect to all the 3 pins to then for the wires to go to whatever component they need to go to next, for example ? {the 'solder-fume-extractor's' wiring picture where you can clearly-see where all the wires connect to all the components is the only type of simple diagram i can read by myself}

Still wiht me ? i lose myself sometimes!

So as i understand it, from what ive been reading so far, as long as the voltage output of the battery pack is correct, say for example for my wireless camera, if ive used a semiconductor to get the voltage of my power-pack down to give an output of 8v rated to 500mAh, as the device (wireless camera) only uses a max of 200mAh, then does this mean that the device will only use what it needs and ignore the rest ?

Also it has taken a week of help from many friends of mine to help write this question and to keep it on-track with my main goals for the 3 power-packs listed above! if anyone needs more info, please let me know and i shall endeavor to reply as soon as humanly possible, again many thanks for your help

Again, many thanks in advance for all help given and i sincerely apologize the long speech of a few questions, im afraid i get too-specific when asking for help (and often branch-off far-too-much, like now, lol)
