7XL 0r 9L with BK 9920 on LIPO?
 

Would a 4s lipo pack be ok to use in my EVO or RACEBOMB with the stuff mentioned titled ?. Also i would use a trition charger because thats what i have.

No problem at all, rcheppie.

Make sure you get a low voltage cut off or detector.

Would the trition charger be okay also ?. Maxxamps has a 4000 4s pack that i was looking at. Are there any other 4s packs in that price range ?.

That is fine for the triton. It can do 4s but only at 2.5 amp.

Hippie, are you gonna get 2 2S packs or one 4S?

If i do it i will get one 4s pack. Maxxamps said they can make me a 6000mah 4s pack.

Wouldn't you be throwing off your weight distribution?

Yes it would i just dont know which is the better way to go for me. Two packs costs more than one.

Could i use two 2s2p 8000mah packs in my EVO or RACEBOMB, or is a single 4s pack better ?.

There actually gonna be the same thing, just in different configurations. I would go with the 2S2P packs. It shouldn't cost any more. Maybe, 5 or 10 dollars for the wire, connectors, heatshrink, ect.

You could go smaller 2s packs like the 6000 for weight. They 80 a pop verse 110 to. Get two packs for 4s 2p 6000 mah. for under 600 grams of weight.

If i go with either two packs of (6000 2s2p) or two packs of (8000 2s2p) can i charge both of them at the same time on my triton charger ?.

Well that is up to you. Some say yes some say no. It would be faster to charge them in series. I would stop them before full and charge seperate to the full charge.

Leroy if i chrage them both at the same time by a jumper from the charger they would be in series.

Yes, that would be in series. But with the Lipo packs, i would charge individually with triton charger. IMHO
