any how..I have Turbo 35BL and wondering if i should cycle it like 3 times at 6Amp charge and 30 amp discharge (off roade mode)?? Will this help ?? I like to keep this pack to the max performance for my stock...and for a long time!
You should of gotten the Panasonic SMH's or UMH's for stock racing. They have more punch. The number's on my panasonics are [email protected] discharge/5A charge with 18-19IR. Them Sanyo's have an IR of 24-26.

Superk
Use at least a 7a charge with an .07 drop back voltage. Hv's have been charged at up to 10a, but 7a seems like a good starting point. Your batteries will be fine.

How about 7A on my old 3000H ??

I charge most of my at 5A... and peak it at 6A.
************************************

I also have panasonic 3000 ..and last time I charge it ..some how I hear a Puff sound from it a few times......why is that? is it bad??

7A is probably a bit high for the old 3000H

the "puff" sound is the cell "venting" - it probably lost a bit of electrolyte, which is bad for perfomance, but the cell may still work.

Does changing the charge rate during charge hurt HV's?? my pro-trak does this automatically, when the pack gets to 0.03 or more fallback the amp rate slowly rises to a user set level, currently it rises from 5.5 amps to 6.5 amps. i've allways used this but just wondered if it was hurting the cells at all as no other chargers i know of have this feature.
Also my packs seem to have better charge numbers when the ambient temperature is hotter, has anyone else found this? i ussually get about 94% power on my pro-trak but on saturday it was the hottest day of the year so far and i got 97% and a slightly higher capacity.

I would switch the increase function (is it called turbo?) off personally - NiMH's are sensitive enough as it is that I wouldn't want to start working them harder just as they reach their limits.

Never noticed any difference with warmer ambient temps, but never been looking for it either!

I started charging my 3000H practice packs with the same rates as the HVs. I wasn't worried since they were older. I will say that they do act much more like the HVs when charged that way. As for longevity, I don't really know since I'm kinda running them into the ground anyway.

I charge my 3000H at 5 amps and .07 as per Danny at SMC SMC Go to products and then select maintenance for the tech info.

Default tekin bc110l ??

I've just bought my first HV's and am waiting for a new charger to arrive. In the meantime I'm thinking of charging them with my tekin bc110l. I've read quite a few posts re using older chargers with HV's, and guys like Danny from SMC, and Rick Howart suggest using ni-cad charge profiles for HV's. Does anyone out there have any experiences, good or bad, using a tekin or similar older charger?

thats all you use for hv and smh. The nicad chager is like the "normal charge" the Niam profile is for reciver packs and other small things nad chagers really really low amps. Except for the millinimem pro which I think has a profile for hv and smh, not sure on that though.

Tad, for charging NiMH's, you only what to use a linear charge on them. DONOT use a flex or pulse charge on them! I use to use a Tekin 112C to charge the first edition Panasonic 3000's. As long as you use a Linear charge(no pulse/flex) and the peak detect is set at .02V/pack you'll be in good shape. The default peak detect/voltage threshold programmed in my Tekin was .04V/pack. That's .02V's too much for today's Sub-C NiMH's. You best bet is to get either a Novak Millenium PRO, a top-of-line Integy with adjustable peak detection down to .01V, a CE Pit Bull or a CE Turbo 30/35 charger. I'm sure there's other high-end chargers out there but these are the ones off the top of my head. These R/C NiMH batteries DONOT like to be overcharged. Also, charge at what the matcher charged at.

also, you DO NOT want to "dead-short" these batteries nor leave them stored away for more than a week at 6V's a pack. If you're not gonna race again untill 2 weeks, put them on the charger for about a minute and store them. These cells seem to loose their voltage by sitting around and if stored to long you can hurt the cells structure which will give poor performance.

Thanks proudwinner. I am waiting for an Integy 16X5 to arrive, but am wondering if the tekin bc110l is a linear charger. Does the " l " refer to linear?

Lemme check out their website. If the charger doesn't have a pulse/flex feature then the charger will only charge linear.

Well it looks like they no longer have a website. Most likely it will only charge in linear unless you see a way to add the flex/pulse feature. If you have no other way to charge(except a time charge) then your okay. Thing is, that charger has a high peak detect for NiMH's, it doesn't for Nicads but thats a differant story. I wouldn't use that charger to charge NiMH's unless you monitor your voltage drop with a high end volt meter that reads down to a thousandths of a volt and when the voltage drops .02V's cut off the charger but man thats hell to watch a charger.
