There are 4 lipo cells involved in a saddle pack. For example, on a 4200mah, 2cell, 7.4v saddle pac..... Each side of the pac has two cells wired in series for 7.4v nominal. The individual side is good for 2100mah at 7.4v. Then these two sides are wired in parallel to yield the final mah.

Dont believe me? There is a person with the screen name duster 360. He has posted many messages about wiring. Look him up.

No. A 2S (not 2S2P) saddle pack has two lipo cells total. One in each of the two packs. Each pack is 3.7v @ whatever the mah is for the entire battery. EX: AE 5200mah 7.4 saddle pack - each of the two packs is 1s (one lipo cell), 3.7v, 5200mah. If each of the two packs contained two lipo cells you would need two balance leads ( they only use one) and in fact, you can charge each pack separately without using a balance lead (nothing to balance as its one lipo cell).

Yeah I've read his posts, and he's right. A 2S2P lipo does indeed have four lipo cells. The problem is they aren't all 2S2P.

That is what I have just learned. I looked at several packs. The Reedy pack I looked at was two cells, the Orion I looked at is available in a variety of configurations, The Protek saddle pack I just looked at on Amainhobbies.com is listed as a 3P2S, which is depicted in the diagram below. SO in fact you can have 1, 2 or 3 cells per side, and still get the 7.4v, and one balance connector.

Take a look at http://scriptasylum.com/rc_speed/lipo.html. You can play around with different types of configs. Pretty interesting.

Ok guys so I have a Orion vortex R10 pro in my b4 right now I am running a 17.5 in it but I will soon to be putting in 8.5t. My question is I was going to buy the vortex r10 race with a 6.5t in my b44. Would it be better to put the pro in the b44 or will the race be fine.

Also what is the big diff between the pro and the race? Thanks for your help q

What length shocks did you buy? 30mm fronts and 38mm rears? You may need to get some longer screws and space them away from the tower, but other than that they should fit just fine. Look back a few pages page 116 #1737 and check out my pics with my standard velvets with BB springs on them. I put 2 limiters in the back and one up front to keep the dog bones from popping out. I used the losi bottom cups and associated 1779 FT shock eyes to get the right lengths and travel needed. I've also been using losi yellow rear springs and blue fronts. I hope this helps.

What top caps are you using? Use the longer ones on the front if necessary.
