By soldering the jumper directly to the tab of the cells. This would reduce the resistance as there would be one less connection and no connector to go through.

Saddle pack sales are far from stellar compared to other models so I don't think it would be worth doing but the current design with jumper wire and connectors is not very good but it's what everyone seems to use. One way to improve the current model is to use solid 4mm male connectors instead of the higher resistance split style that come with all cheap inboard packs. Our saddle pack comes with solid low resistance connectors on the jumper wire. I will post some data tomorrow on the difference between both styles.

I just put your connectors on my power wires, they do seem nice. Interested to see the difference between wire & direct solder.

danny, back to your question from a couple days ago about the higher IR packs...

you sell these three packs: 1) 6500/60C for $40, 2) 6500/70C out of spec higher IR for $45, and 6500C/70C for $55.

since you base your C ratings on IR within the line of batteries you buy from, why not just call the out of spec battery 65C and call it a day (is it because you don't want to print another label?)? it would appear from the pricing that the out of spec pack is in between the 60C and 70C with respect to IR. if that's not the case, then obviously the pricing is off somewhere, or maybe not if the higher IR pack is closer in IR to the 60C than it is to the 70C.

i guess the question come down to: are these out of spec, higher IR batteries an anomaly or is it something you want to continue to offer? if it's the latter, i think calling it 65C would lead to less confusion within your line of packs. if it's the former, then what you're doing to get rid of the higher IR packs is probably the best way IMO.

just a thought...

I broke my servo for my agama last night @ practice & no one in the country seems to have the gear set in stock. That means I won't be able to race it & test the battery this weekend. It will be 2 weeks until the next race, but I hope I will be able to get it fixed for a test day before then. Sorry for the delay in testing the battery.

The IR of the 6500-60C using our ESR meter is 7.36mOhms using the ESR meter. The current 6500-70C with higher IR are 6.48mOhms.

Not possible to offer these all the time as this is just a batch with higher IR the factory is going to resolve this for sure. So making a new sticker makes no sense. I know this is confusing to many but anyone who has any questions just let me know. Maybe I should of said that we got a batch of 70C in that are actually 65C based on my testing. Actually I could claim 80C as some so called 80C packs I tested have higher IR than our current 70C. This is the issue with the battery market right now there is no standards and no ethics. Just print what you want and sell it.

I have a so called 6000-60C here from another supplier that is 9.64mOhms. This is one of the reasons why I like to share info and show to everyone how much BS is in the Lipo market.

Bottom line for anyone who needs a great pack at a great price buy the 6500-70C and 7200-70C with higher IR while supplies last as these are great packs for the price. If you race in a class where maximum punch is needed then wait until we get a batch of packs with the IR back down. For offroad modified and for bashing you won't go wrong with these packs.

Sorry to hear that. No problem on the testing seems guys like the packs performance for the price now we need to see how they will hold up over some more cycles.

OK. that makes a lot of sense. I thought you were asking about the feasibility of the higher IR packs long term. if this is just an anomaly from your supplier, then people better snatch them up quick. sounds like a terrific value.

Yes but I think since I use higher IR it scares some people. In fact lower C rate or higher IR is the samething but guess everyone is just use to C rates even if that means nothing nowadays.

I really need to find a way to tap into the Traxxas/RTR crowd as these guys would love these packs and I don have access to more of them as my new shipment that is ready now is higher iR but I don't need to take it. If I would know these would sell well then I would stock up on them while they are around.

If anyone is able to help promote our packs in the Traxxas and basher market then please contact me via PM or email.

Here is a test I did on the different connectors on the saddle pack. It shows that split style 4mm connectors are very good.

Test done on a saddle pack with jumper wire. IR measured at the male 4mm + and - connector.

Split style: 9.32mOhms

Solid style: 7.92mOhms

Split style on jumper and solid on + and - connectors: 8.32mOhms

Cells with no jumper: 7.12mOhms

So a jumper with solid low resistance connectors adds 0.80mOhms of resistance. This could be cut down by soldering the jumper straight at the tabs but I don't have time to test this now. A jumper with split style adds 1.20mOhms.

Ran the 2s 7200 70c high IR pack for the first time today. Started by fully discharging and recharging 6 times. Pack took 7130-7250mah each time. Tremendous, very happy to see full capacities. Ran back to back with my previous RevTech 6500 60c packs, the SMC had a noticeable increase in punch and also held higher voltage through the run. I managed a TQ in 17.5 Blinky stock sedan (I know, it's not off-road ) by nearly half a lap, had a 3/10th faster fast lap, and had an average lap time as fast as third place and lower's fast lap. Certainly not a bad debut for the new batteries. Unfortunately I neglected to do some basic maintenance to my car going into the mains, and was left with a car that simply would not rotate consistently. I managed a close second but feel like I could have done significantly better if my car was on pace to where it was in qualifying, and maintained its consistency.

A lot of interest in the batteries, everyone was scratching their heads wondering where I found all the horsepower since our last weekend points race. Tried to drum up some interest, hopefully you see some new sales going out to Minnesota. I know I'll be ordering some more new packs in the near future.

Traxxas has forums on their website but you are not allowed to advertise at all on them, they won't even let you post a link to any website exept to traxxas.

Big fan of SMC, every pack I had in the past has been ballistic. Tried to purchase a 7200 pack but there is a UK distributor here who does not stock it, and it seems won't order it until the current stock is depleted..:cry: Sad for me happy for Thunder Power, who I believe are one of the few who actually do make a pack with genuinely high performance, but since Schumacher took over distribution I've been forced to pay £90/$130 for a premium pack. $260 for two packs. I've decided only to use them in big competitions so as not to put too many cycles on them because they cost silly money. I would have got the 7200 pack in a dash had I been able to.

Thanks for the feeback Rocky. Seems like some guys get good results from these higher IR packs and others notice a lack of punch. I'm glad that these work well for you and once we get the IR issue resolved you should give one a try and see if it does make a difference in your application.

Now what I need to figure out is should I bring in some more of these packs with higher IR and keep offering them at a lower price or just wait until the newest batch of packs gets done and the IR is back down ?

You will be very happy soon as we're opening up SMC UK which will sell direct online at very good prices for the UK. Not possible to be the same price as the US as importation fees are high in the UK but I think we will set a new standard for good prices on high end packs for UK racers.

As soon as the IR issue is resolved packs will be on the way so hang tight.

Great news :) Please homologate !
