Hello Nerfers!

I currently run Ultrafires on my fully rewired Stryfe(1st Gen).

But I have a few questions to ask.
PLEASE ANSWER ACCORDING TO NUMBERS. DON'T SIDETRACK SAYING:"Why don't you wanna cut shells?, or why are you using LiPos?
Answer like this:
1.Yes
2.no
3........

1. If I run a 2s 25c LiPo, will it be weaker than Ultrafires or not? (High Discharge but low voltage)

2. If I run a 3s 20c LiPo, is it necessary to change my rev switch into a high current micro switch?

3. If I run a 500mAh pack and I'm playing for 5 hours, do I need to bring 2 packs? (don't want to cut shell)

4. Can aanybody give me a link for tutorials on how to charge LiPos using a smart charger? (maybe an IMAX B6 Balance Charger?)

5. My LiPo has a JST discharge plug and a JST-XH balance plug, if I want to plug both into my Stryfe or my balance charger, what terminals should I use for the Stryfe and the charger? (Male/Female)

6.Do stock motors spin fast on a 2s LiPo? (Related to Question 1)

7. How do I solder a Female JST plug to my wire to plug LiPos in? (if you have a link, it's fine)

Thanks a lot guys :)

No need to be a smartass about it.

To answer 3, 4, 5, and 7;
3. Better to have and not need than to need and not have
4. It's actually fairly simple. Just make sure you have the correct charger with correct terminals, read the directions on where to plug in and how long to leave and you'll be fine.
5. I'm not familiar with the JST plugs, but AFAIK you do not need to plug the balance plug into anything but the charger. If you have a local hobby shop, ask them because they'll know what you need and will give you the parts there.
7. If it has two metal prongs to plug into a plastic shield (most likely) then it's pretty easy.
Assuming you know how to solder, just solder one prong per wire, then put the negative wire/prong into the negative side of the shield, and then put the positive wire/prong into the positive side of the shield.

1. If I run a 2s 25c LiPo, will it be weaker than Ultrafires or not? (High Discharge but low voltage)
A. It will be equal to running 2 ultrafires
2. If I run a 3s 20c LiPo, is it necessary to change my rev switch into a high current micro switch?
A. Maybe the original switches are rated much lower they will eventually burn out and don't pass as much current but stock motors on 3s you can skip the switch upgrade for now you should think hard about doing it eventually.
3. If I run a 500mAh pack and I'm playing for 5 hours, do I need to bring 2 packs? (don't want to cut shell)
A. depends on motors and play style how heavy handed you are on the rev switch. From what i have found 800-1000 is the biggest that fits in a stryfe with a little bit of modding as in removing dividers and support ribs on the battery door
4. Can anybody give me a link for tutorials on how to charge LiPos using a smart charger? (maybe an IMAX B6 Balance Charger?)
A. Google youtube then "how to use imax b6. first result
5. My LiPo has a JST discharge plug and a JST-XH balance plug, if I want to plug both into my Stryfe or my balance charger, what terminals should I use for the Stryfe and the charger? (Male/Female)
A. The stryfe wont have anything you will need to install something to plug into the balance port and the discharge the jst is what you will plug into the stryfe you will need something like this
6.Do stock motors spin fast on a 2s LiPo? (Related to Question 1)
A. I find they do fine on 2 IMR which would be like a 2s 700mAH 10c
7. How do I solder a Female JST plug to my wire to plug LiPos in? (if you have a link, it's fine)
http://www.amazon.co... plug connector
https://www.youtube.com/watch?v=oqV2xU1fee8
it should be pretty self explanatory you run the two wires into the guts of the stryfe and where the 2 wires connect to the battery tray you connect the jst

google and search will both give you numerous how to on modding the stryfe most commonly a rewire mod first result on google search https://www.youtube.com/watch?v=o4AR9fvwlYw ONLY thing i have to say about the video is those "resistors" are not resistors they are Transistors they drop voltage and increase amperage but are not needed.

odd how all of your questions are not yes or no...

another useful bit of knowledge is here is a listing of max acceptable amperage for a given wire size we would be looking at both chassis is more short bursts and what we would use primarily but for longer use the transmission is important too as at a given amperage the wire will heat up and eventually melt
AWG max Amp chassis  max Amp power transmission
10	55	      15
11	47	      12	
12	41	       9.3	
13	35	       7.4	
14	32	       5.9	
15	28	       4.7	
16	22	       3.7	
17	19	       2.9	
18	16	       2.3	
19	14	       1.8	
20	11	       1.5
