it's a new charger and only speedtechrc has it. it was use by hara and surikarn at jmarc in japan and in japan itselt already sold 10,000 unit. the charger has a 3-step charge mode. my friend bought one his 3300 olds packs use to peak at 2800mah w/ the new charger it peaks at almost 4000mah and w/ a high voltage w/in a month i will get one. more info visit the web.

If it uses a three step charging method it could pump the Mah up by charging at say 6 amps then lower then even lower again. Remember that you want linear charges unless you are trying to break up the crystals in your cells (shock an old pack back to life). Most people will recomend 6.0 amps with .03 cutoff. Your packs should peak off around 9.0 volts and the temp should be around 140 degrees. I dont dead short and I have always had power to spare.

Beanster - welcome aboard!!

A 6 amp charge is a good starting point for 3300's, but .03 threshold is usually too high for the latest generation cells - Try .01 first, if your cells don't get to around 140 degress bump it up on the next charge until they reach that temperature. The reason I suggest this is because if your peak detection voltage threshold is too high, you will loose voltage as you're actually overcharging your cells.

Rule of thumb - Start low, gradually work up.

I haven't seen this new charger, I'm gonna have to look into it.. So many extreme charging choices!! I'm finally using a GFX <grin> and I have to say I still liked the Futaba CDR's features better. In the whole week I used it before it died, it showed me it had features the GFX just can't touch.

Actually slick thats what I have been doing since Panosonic 3000's. Ive tried just about every method. Being in Trinity country allowed me to get alot of packs and ideas and this was the all around best.

Default I am confused about these new 3600/3700/3800

I am not that knowledgeable about electronics.

It seems that voltage is the standard by which everyone grades batteries. To the point, that 5 hundredths of a volt (difference between 1.75 and 1.8) is considered significant. In a 6 batt pack that is 3/10ths of a volt difference during the flat part of the discharge curve 6.9 volts vs 7.2 volts.

Since at least for stock racing any 3300 will go 6+ minutes
Where is the gain from using 3600+ batteries?

Isn't there away at least theoretically to increase voltage using a transformer. Would it be possible to use the additional storage capacity to hike voltage? and give up unneeded extra runtime?

Transfomers work on AC, not DC.....

You can increase DC voltage other ways, but at the expense of amperage...

It's all part of the create/destroy energy thing...

Well unfortunately the only racing I saw was the Bud Shootout last night. Had to work this weekend. Local track was closed though because most of the guys went to the snowbirds. Hopefully things will get cranked back up next weekend.

Finally got to run for the first time this year. Club race in Stockton, CA. Comp is tight in Northern Cali. 8 cars in mod, all on the same lap in qualifying. Got punted in every heat, qualifed 7.

Got a good start in the main, up to 5th. Picked off another car and started realing in third. The car that was running behind me had more corner speed than I did and just drilled the back of my car, pushed the back of the body in and had to wait for a marshall. Got going again and finished 6th.

A bad day of racing is better than a good day at work

Gotta find some corner speed though, need about 3 tenths a lap. Car felt good though.

My next race probably wont be until the State Carpet Champs in March. We get one whole day for practice so I should be able to get the car sorted.
