Compare to an old HobbyKing Nano 4600 standard shorty on the first cycle today (cold):

7.8v - 44s
7.7v - 78 s

7.5v - 149 s
7.4v - 200 s

SEC 510
IR 7.9
MAHr 4250
Ave. V 7.34

This is a junky practice pack. The lcg has maybe 5 cycles on it since it has only seen the turbo for testing. Charge at 10A, discharge at 30A
Is that representative of LCG as a whole, or is that a specific LCG pack?

That is one pack, but I have another pack from a different brand that wasn't much different/better. And they are shorties, which might be part of the problem.

When charged to 4.35 it barely made over 8000mah. LCG is nothing more than lowered case with the same chemistry
That's only if you buy the HV version of them. Any Non HV pack should reach its capacity or writhin a few percent of it at 4.20 per cell.

The HV packs capacity is rated at 4.35v per cell and why you never get that capacity at 4.20v.

It's not always true. I was a firm believer in the 8200 pack I was selling for a long time and also the IP packs like a lot run that are 7600+. Until my factory sent me a newer style 6000 pack to test. The discharge curve at 40 amps is just as good if not better than the IP packs and my 8200 pack. Plus the IR was lower. It all depends on the chemistry of the pack itself.

One thing I also found when testing HV packs were they were good the first 15-20 cycles and then they went to crap and swelled worse than any other packs Ive tested. It's been about 6 months since I tested any so perhaps they have refined them a little better but I always thought the HV was just a gimmick to be honest.

The latest Nosram/LRP 6400 HV/LCG Graphene seem to be one of the best batteries around at the moment guys using them in blinky boosted and mod, voltage holds up really well and gives lots of punch for blinky racing as well. Probably why there is no stock here in the UK at present at suppliers

The down side of 8000mah lipo and above is that they weigh a ton and if you have a A800 like myself which is naturally a light car good luck with that L/R balance

Well I guess testing every pack over time is the only way to go. I just hope more racers would post more videos of their tests.... So far , the turnigy cells seem to be still good for the price, but I seriously question the crazy charging practices I've seen in the pits, with not much more performance gains to just charging at 12A , with no discharge..... Maybe the new cells don't like these practices, and should be charged normally...I remember pulling a few of these racers down the straight with my normally charged fantom 5000 mah(12A) in an overweight tc4 with too much toe (f/r)...Yes they got me in the corners, but they had newer motors/batteries/chassis, and weighing exactly 1350g....There might be a mystery to finding speed, but I will pass on torturing my packs for that last 0.1 second per lap....I might get further trying something else...

Bert, I hate to do this to you but...

The industry standard for charging is 1C, so a normal charge on a 5AH battery is 5 amps. So a 12a charge is pushing the batteries, just not as much as everyone else.

You don't have to go to the mat to get a little more out of the batteries. Discharging then charging does seem to work, but you don't have to do it at near nuclear rates.

I did not push the batteries enough at 12A according to the guys in the pits who charge/discharge at 40A... I know 1C is the standard, but that is more geared towards avoiding lawsuits more than anything else....

Simply being a shorty will do that. We need to compare LCGs to their equivalent length packs to get a fair picture.

That is what I did. I was pointing out that those who got good results with full length LCG packs may have done so because they were full length. The short LCG packs I have are not that good compared to standard short packs.

My bad, I didn't notice that the "standard" pack you compared to was also a shorty.

I tested all my batteries last night on my turbo GFX and the LCG 5000mah Fantom held the voltage over a 6 minute 20 amp discharge as well as my SMC 6000 mah 2s full size packs. They were also .10 of volt higher on the start of discharge to the end of discharge over my GensAce batteries. That was 3 Fantom LCG 5000 2 SMC 6000, 2 GensAce 6000mah, 1 GensAce 6500, GensAce 5000 mah, and a GensAce​ 5800 mah.
The SMC had the lowest IR 1.6 average per cell, LCG 1.8 and the GensAce were all mid 2s IR. In 6 minute's the packs all of them had a 1680 range of mah drawn out.
