Roaring top

That's what started me looking for other options after 3 Revos with bad cells out of 6 packs 2 dinogy 4s 5000 mah puff. I'm not knocking either mfg. because it could be a case of my bad luck because I do have other Revo 40c packs still going. Part of the problem is buying lipos in Canada is shipping cost my last order of Revos shipped with FED EX cost me an extra $36.00 for handling because they split the order for 4 3700mah 4s packs in two boxes. I want to look into the option of picking up at a U S post box and not deal with Fed Ex. So Giant power or Dinogy graphine could be a option.

Yup actually all the HV's have been puffing. Slightly but...
I believe it is just in Canada that the extra charges occur from Revo. If you can pick up across the line you may be clear. I may do that next time but also try the 420's. My pal in Victoria has not had issue with these.

It's been a hard summer on the majority of my 3S 420 Revo packs, a lot of testing, but never really run them down past 3.8-3.75V. The occasional 3.65 if I got the timer wrong on a new setup. They're all puffed slightly. They seem to still be running well, but the Turnigy Graphenes and Nanotech's from last season that I repeatedly ran down to LVC before I knew better are all still perfectly square. IR's in the Revo's have gone up some, but are all still under 2.0 and all balance within .002-.003V. I'm certainly keeping my open to try something new.

Tested the roaring tops in speed run cars the 5100/80 c 4s,, I found them just as good as the big china hobbies with are the same as the big turnigy graphines but the china's do have slightly lower IR and the RT have a higher discharge we got less of a voltage drop with the RT I do have some new 3s 5100/80 RT for sale

I ran a pair of Revo Go packs, 4S 5000mah 60C way down a couple of weeks ago by accident. I was going for runtime not top end speed, but was relying on the LVC to kick in but I learned a thing, make sure LVC is set at it's highest setting. I an running a RCM telemetry set in the boat and will use the alarm on that to warn me when the voltage gets down in future. They were running in 2P and took over 4900mah to recharge each. No puffing and cell voltages/IR's do not show any change from before. So far so good with them in this way, which is great as I don't think they have the same punch for ovals as my 3 year old 427's even though those only ever get charged to 4.2V.

Peter, so those 60c’s were the Platinum series? There is still a few of those left on blowout pricing.

Sorry I got that wrong, they are 70C Silver series. To be fair I am not that impressed by the IR's, they range from 0 to 7 mohm in the packs. They may be better in warmer summer weather, but the differences within the packs are questionable. My 427's still sit at 2-3 during winter and those packs have been raced hard at times.

For you guys in Canada, dinogy will ship usps priority mail. Just pick that option during shipping.
