They are both charged to 8.4v (which means the 6100mah pack only had around 5400mah in it) and they both have the same IR, which is a direct result of the health of the cells being the same. If a current generation battery is a 7.4v nominal pack it will do the same thing. You lose, you are wrong. Post a video just like I did proving me wrong.

I backed my claim with a video. If you think the generation of the pack has anything to do with it, post a video backing up your claim.

Your LiPo instantly dropped to 7.4V as soon as the current ramped up to 20A. That's not healthy.

I'm still generating the graphs but here's a sample from one of my LiPos:



As you can see it's still higher than 7.4V after around 6 minutes and is still under a 20A load. The resting voltage was 7.8V when I stopped the discharge.

That's because I tested a true non-HV pack who's nominal voltage is actually 7.4v against an HV pack charged to 8.4v

You've only replicated the part where I tested the HV pack, where is your test of the cells that rest at 7.4v @ 50% capacity?

You already said that charging an HV cell to 8.4v lowers the nominal voltage to 7.4v, but your test proves otherwise. Show the charge curve of that same pack after 50% of the capacity has been put into it and the resting voltage will be 7.6v.

You said all current generation batteries are the same cells whether they are HV or not, but that is just not true. While the pack you have is comprised of HV cells and labeled as non-HV, there are still many packs that are not. Anyone running HV cells has an advantage over anyone that isn't, even if you limit charging to 8.4v. I can give you a list of true non-HV packs currently for sale on amain if you'd like.

No, your LiPo just looks like a dud. Even my old 4600mAh LiPo shortys don't drop their voltage instantly like that.

What part of "I'm still generating the graphs but here's a sample" is unclear? Also, this wasn't a LiHV pack, it was a LiPo.

I never dipped below 50% in that first graph. You can't determine nominal voltage from it. Also, this wasn't a LiHV pack, it was a LiPo.

I give up, you clearly don't understand that hv cells are a different chemistry and it doesn't matter what the sticker on the pack says. It matters what their nominal voltage is at 50% capacity.

Charge your supposed non-HV pack to 8.8v 30 times. If it fails it is not an HV pack, if it survives it is an HV pack with 7.4v stickers on it.

I have no idea how this topic got so off track lol 😂. I suppose I should explain a few things.

1.) I run offroad. At my track we run 1/10 and 1/8 of most major offroad vehicle types (4x4 buggy, truggy, ect.).

2.) My idea​ for a LiPo line offering was based around the fact that most people in offroad try to lighten their trucks by using things like titanium screw kits or carbon fibre parts.

3.) It doesn't matter if LiHV holds a 1-2% higher average voltage while discharging if the reasoning behind this ability is simply the fact that the packs contain Graphine. The new SMC extreme Graphine V2 LiPos are standard 4.20V max per cell and have that same ability.

4.) There is no arguing the fact that LiHV is a waste of weight in racing. Yes, that may be a good thing for you on road guys but thats NOT a good thing for offroad. When you charge a LiHV 5600mAH pack to ROAR legal 4.20V per cell, you are only getting 5000mAH of the capacity charged. So instead of using 5600mAH LiHV cells, it would be FAR more weight efficient to use smaller, 5000mAH standard voltage cells.

What percentage of races world wide tech for battery voltage? The answer is a small number.

My LiHV 6000 pack is lighter than my LiPo 6000 pack. If the two packs are similar weight and are of a similar age and quality, that's usually a good indicator that they have similar capacity at 4.2V per cell. I'd expect a 5600 LiHV to have a similar weight to a 5000 LiPo. When I buy a pack, I check the weight rather than the label. If you do start selling a line of batteries, I'd recommend making the weight of the pack pretty clear in the advertising.

Ya weight of packs in advertising is definitely a big plus and luckily these days its pretty common to see on most currently sold packs. These days I run SMC Extreme Graphine V2 batts because they are incredibly lightweight, good capacity and the punch is up there with the best of them. I just recommend "breaking in" SMC batts because for some reason in the past SMC cells have had a tendency to puff under high stress. However, Ive found that a break-in really helps prevent the puffing from occuring. I haven't had a single issue with their new 2020 cells so far (had them since they came out) and my old 2016 packs had no issues either. They were just getting old so I sold them and used the funds towards the new packs.

I enjoy the SMCs because they are standard voltage packs, but are very powerful nonetheless. Ive had no issue placing podiums with the new 2020 Extreme Graphine V2 4S 14.8V 6000mAH in 1/8 E-Truggy And E-Buggy Classes. Most of them unfortunately already run LiHV and it sucks cuz I wanted everyone to stay on equal ground and comply with ROAR/IFMAR but instead, despite a tiny, twisty track that needs no extra power anyways, they went with extra power lol. The main straight is all of 100ft. We really don't need any more power.

I've only been to one off road track that teched battery voltage.

I've never seen it outdoors at all. Any voltage goes. I suppose maybe spec 1/10th has a 2s limit, but I've never seen a tech inspection of that. All of my 1/8th scales are HV. Half of my onroad cars are as well. But never 12 scale, they need the capacity.

Bring out some lighter high quality 4s packs with 5mm plugs (around the 5000mah mark) and I’d be more than happy to buy them.

i would stand clear of SMC lipos , those packs you take them out of the package and look at them and they puff up,

This may have been true from when SMC was first starting out and they were experimenting with different technologies, but I have seen lots of evidence that they've come a long way over recent years. I too had stayed away from SMC until I started hearing good reports on their newer True Spec Extreme Graphene V2 series.

I decided to give them another try on this pack here in my EB48 20 with a 1900KV motor and I've got roughly 12 race days on it so far without a hint of swelling anywhere on the pack, I just took these IR readings last week:

I can't speak for any of their other series of packs, but I'm going to continue supporting their V2 packs for sure
