When will the weighted lipos come out? So when can quit having add all that lead to get the cars up to weight and balanced out.

Who actually supports soft core porn?

Ahhemmm!! Loving the batteries. TC gets better with testing. Buggy is still a squirrel, but fun. Love leaving the big tub o'crap for Mh at home.

Somebody is because they make way more money than the RC industry does.

Well, My LHS did that. I'm told that Orion didn't know what to do, if they are responsible or the battery manufacture.

If its a heavier pack, then the power/punch of the pack will probably need to be inproved so that it feels like the power of the 3200 or 4800 lipos?

I thought about a lipo testing scheme for some time. If not high constant current load; how about measuring transient response to varying loads? I'm almost certain that if we use impulsive loads and moderate constant current loads in a repetitive pattern it will work. Then graph or create formulas to translate the results to usable data for grading cells. You can also change the load patterns to grade cells for different classes of racing. I can probably build this machine and write the software for it but not out of my pocket! hint hint Mr. Black!
I've thought about something crude in this fashion using some type of pulsing relay (or something like a Heavy Duty Automotive Flasher unit), hook the battery up to something that would pull a constant 15 amps discharge, and have the pulsing relay kick in an additional 25-30 amps for 1-2 seconds at a time, and do this over a timed run period too.

Honestly my speculation is that the next Lipo from Orion/Peak isn’t necessarily that much heavier. I imagine it would weight more than the current 3200/4800 Lipo being offered, but at a closer weight but however at the same time less than today’s 14.1 oz of 4200 NiMh. I think that the new Lipo’s weight will be under that, but Orion will build a feature into the Lipo pack that would allow the user to vary the overall weight of the pack as desired by allowing them to add/remove weights incorporated into the sides of the pack! How’s that for creative thinking and marketing if that were to ever happen?

The truth is I really don’t want the next Lipo to be 14.1 oz like the current NiMh. I really hope not, and if they are I probably will stick with the current 4800 Lipo which is more than enough for 2wd/4wd off-road mod racing. Just adding some oz. of weight to the current 4800 Lipo to make it less than 14.1 oz is perfectly fine, say 12-13 oz. for instance. In fact I personally think the current 14.1 oz NiMh weight is too heavy, slows the responsiveness of your car down, and makes both of your cars prone to breakage when landing off jumps, clipping a pipe, or whatever. I liked it when we were running the lighter GP-3300, and even better with the NiCd 2400 & 2000.

The thing is its not like you have to make the pack to meet the 14.1 oz weight to comply with ROAR guidelines for weight, or for club racing! This is furthest from the case and a misconception among some racers who think that the next Lipo should be 14.1 oz to make it fair, or level the field out competition wise. I think that shouldn’t be the case!

For instance if my memory serves me right ROAR states the weight class for the 2wd to be 52 oz & up, and 4wd to be 56 oz & up. Those are my favorite class to run. The truck is 60 oz & up I believe. The current crop of 14.1 oz NiMh are porkers and heavy, especially with newer ones coming out with larger capacity, and put our 2wd & 4wd well over their respective minimum weight of 52 oz, and 56 oz, and way to heavy in my opinion.

I’m not sure exactly what the next Lipo’s weight should be to at least make our car heavier and lighter at the same time, and at least meet weight. This would be an interesting subject to research at least. For starters the 4800 Lipo is 9.1 oz, but in reality it isn’t really that too hard to get creative and add flat super thin lead weight low to the chassis on the sides of the battery channels (for the lowest center of gravity imaginable possible!) to at least meet each class respective weight if you shop around at sports store or online retailers. It’s very doable!

It would be nice if somebody with a accurate weight scale would weight a NiCd 1700/2000/2400, and all the way up to the NiMh 3000/3300/3800/4200 to get at least a baseline weight reading of how our packs got heavier over time. I personally think a lot would be surprised at the changes of the overall oz. on each pack! I will check around here to see if I can do that for the time being.

A “variable” weighted Lipo pack that you can change the overall oz. weight at the user’s preference would be awesome, and I hope that is the case! Does anyone have any thoughts or comments on this?
