Is anyone running 3800's in 1/10 offroad truck? If so did you have to do any mods to fit the cells or are they pretty much the same size as the 3700's?

What amperage is everyone in 19 turn foam sedan charging their 3800s at? I think 6 and my son thinks 7 for more power. I am concerned for run time with the mod and also the life of the pack.

Arrow Coupons / Sales?

Looking to get some Fusion Team IB3800 packs. Any special or coupons? Hoping to offset the shipping which seems a bit excessive.

Send an email to Jeff or Judy at Fusion Batteries and ask to be PLaced on the e-mail list. Coupons do go out periodically and they go via e-mail.

Chuck,
I have been running the Fusion 3800 for a while now and charge at 6amps with a .02 dropback on the turbo 35. Monitor temp and make sure it doesn't get above 130 degrees. Shouldn't have any major drops in run time with this method. If you have any other questions you can PM me.
See ya at the track
Later
Jim

Chuck,
Charging at 6 amps should be plenty high enough, but the cutoff you will have to play with to get the correct peak temp. Start at 02/20mv and go up from there if needed to get into the 125/130 degree range. The voltage curve and capacity on 3800's is so good you should never have a runtime or power issue.

Aaron's Fusion 3800's have been great he finally got his first TQ at SoCal in 19T touring. He set fast time both rounds and had the fastest lap of the night. Due to some untimely contact about 10 laps into the main he had to pull off when his wing was torn off the car. His 3800's even out performed some lipo 4800's that were tested by a driver!

Hey guys I'm thinking of getting a few new packs, was thinking of the Fusion IB3800's, but was wondering what would be the best choice for Stock racing? Any replies would be appreciated thanks.

I'm using IB3800s for stock sedan racing... and pretty much everyone else I know at my track is as well.

I'd recommend buying the highest voltage Fusion packs within your budget... and favor voltage over runtime.

Good luck,

Bob

Thanks for the reply Bob, I placed my order in for the 1.20 sec av voltage pack from Fusion today. I was just wondering, how many packs do you usually use for a race day? Do you use the same pack twice? Thanks.

I just got back into racing this year and started out with 3 Fusion packs. We run 3 qualifiers and a main, so that along with a pack for practice meant I used 2 packs twice in a day but allowed them to completely cool (at least 90 minutes) between uses. This is pretty hard at cells so you may want to start with a little more if your budget allows it.

Hello Mr Malin. I have a question regarding stick packs. My instruction manual for my LRP Pulsar2 charger states that for stick packs > 1500 mAh I use 4.0A (charge) - 50mV (delta peak) - Flex Mode? I have read numerous articles online about Flex vs Linear charging, and everything goes toward Linear. The batteries are being used with a Mabuchi motor, so I am looking for punch as runtime is not an issue. Each article also refers to straight, or saddle packs and not stick packs. I am going to try charging at 6.0A, and adjust the Delta Peak to stay under 120 (F). Thank you for any input you, or any others might have :-)
