Default LCG Batteries are they as good as regular batteries

That is my question are LCG batteries as good as regular batteries the one pack I bought seem to have good IR 1.5 but I wanted to know what you guy's experience with LCG batteries.

I have owned most of them an they have similar numbers to full height. As they should since the insides are the same just not as tall, same as shorty packs, same internal chemicals just a different shape

How did it improve or not improve your car to use?

I have run a couple LCG style short batteries on my turbo 30 and the numbers are not very good vs. a regular short battery. Voltage doesn't carry as long and the IR is not as good. IR was a bit surprising as I did not think there would be a difference.
I plot time in seconds to 8.0v, then 7.9v, 7.8v etc. to get a simple curve.

The full length packs may be a little different.

I haven't done any testing yet but I'm looking at these batteries with a great deal of sceptical eye.

I just got in some of my new LCG 6000 mah graphene packs I am releasing and they are every bit as good as my full size 6000's I've been using all season. IR, voltage and curve are all just as good.

The shorty packs I haven't gotten to test much yet. But I do plan on having those as well very soon in the graphene formula.

If the have less Mah than the full height, they are not going to have as much voltage and end of run...

If you are looking at two batteries, same Mah one lcg and one not, they are going to be very similar. I have had the LRP full size regular height and LCG, same mah, same performance on track and in charger measurements, same with Team Powers same with Trinity

If you buy these new 2017 LCG/HV/SVH packs don't expect them to reached they're Mah capacity at 4.20/8.40 volts, example I have the Reedy 3.8 Zapper 1s lipo that charge up 7100ish in Mah capacity at 4.20 volts. When charged to 4.35 it barely made over 8000mah. LCG is nothing more than lowered case with the same chemistry

I have a Fantom 5000 mah it isn't a high voltage pack. I race USGT so the car is pulling less then 2000 mah during a race. I'm more concerned about voltage over the run.

I'm never on the cutting edge of this hobby. Can someone post a link or explain exactly what a LCG battery is? I assume it means Low Center of Gravity? I also assume they might be not as tall as a "standard" lipo pack? I would assume a LCG battery might also be a good option for older/heavier cars or cars that have a lower top deck.

If all of the above is true, it might be a good option for someone like me to help get an old tub chassis car closer to minimum weight for classes like VTA or USGT.

The number that soured me was the time from full charge to 8.0v. The LCG pack was very quick - I can't seem to find my notes but it was significantly worse than a normal shorty, and the rest of the discharge followed suit.

It depends on the amp draw.... At 40amps, almost every pack dips below 8 volts immediately.... I am hoping that the new cells can hold 8.3+ volts for at least thirty seconds...

Not the point. Testing everything at the same load, a battery that holds the voltage longer is better.

Just threw the lcg pack on the turbo, note these numbers are the second cycle today:
8.0v - 2sec
7.9v - 3 s
7.8v - 5 s
7.7v - 8 s
7.6v - 12 s
7.5v - 30 s
7.4v - 69 s

SEC 340
IR 11.8
MAHr 2833
Ave. V 7.18

Compare to an old HobbyKing Nano 4600 standard shorty on the first cycle today (cold):
8.0v - 7sec
7.9v - 17 s
7.8v - 44s
7.7v - 78 s
7.6v - 109 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

Totally agree Mr. King

Nice to see actual data!

More Mah= more volt over the run


Can't wait to see you in F1 at CTS this weekend
