I have one of these and it claims to have Lithium mode do you have any experience or feedback on using one with the ATX30?

The RS-30 is a full and REAL 30Ah battery... and though Volt Phreaks are claiming their VPH-1200 is 44Ah, it isn't true. The reason I say that is because we all use a Lifepo4 Lithium Chemistry, and the fact is it all weighs roughly the same. So if you consider the fact that 1 Ah of Lithium in a cell pack without the case is about .25 pounds ... and when you run the numbers you will see that Volt Phreaks are claiming a weight of 8.75 lbs at 44Ah you will find this is not accurate, because to have a 44Ah Lithium battery it would have to weigh a minimum of 11 lbs and without a case. So their Ah is about 30 in real life when you run the math, not the 44Ah they claim. But now you can see our RS-30 weighs more. VP-1200....8.75 lbs compared to ours at 11.5lbs. So our extra weight on the RS-30 comes from the fact that we use a larger case and designed the case to be more of a automotive style battery with a footprint and terminal locations that are aligned with the automotive standard. Also being our case is of a thick-walled fire resistant plastic adds to the weight. But this is done intentionally so that in the event there is any thermal runaway issues with the battery our case can handle the heat much better and keep any issues more contained within the battery. So I will give them the weight advantage all day long, with ours being an overall safer structure. But have to say... on pricing we are half the price... and this is not due to lower quality, its due to volume and much larger scale... we probably sell 100 to 1 what Volt Phreaks does, but we are in more channels like off-road and Powersport and Motorcycles also.

What is the weight of the RS-30 battery mounting kit?
2lbs... it makes the battery 13.5 lbs with the kit. But then the battery uses factory mounts without any mods to a Porsche after being put in the tray.

Does the RS-30 require a special Li-po charger or can a standard charger be used?
You should always use the proper charger for Lithium, which is a Lithium Charger. The reasons are that a Lead/Acid charger has the potential to go into its De-Sulphate Mode which can spike voltage if you put it on a lithium battery. Also a Lead Acid charger will keep cycling the battery at the end of the charge cycle to take into consideration the Lead/Acid Batteries "Natural Discharge" which Lithium does not have.

What is the country of manufacture (not just country of assembly) of the RS-30?
China for the RS-30.

Do you have any professional race teams using your batteries? If so, which?
I see above you brought up that VP is used by tons of Race Teams... and Braille is even beyond that, but that is in the "Street" segment. But we come from Off-Road, and have most of the teams using us on that side. I don't think Braille and VP would come over to our side because they would need to make a better battery that can handle it. Its a different level of abuse for a battery. We think that Road Racing is "sissy" stuff for our batteries (I'm kidding). Keep in mind we are in thousands of Street/Race Cars already and have been for many years, but it is not where we focused or marketed, so we are under the radar there. We only just started to focus on Street Cars this year when we saw that Category was getting the wool pulled over their eyes by Braille and their $1500 to $2000 dollar lithium batteries that had no protections or advanced Battery Management System... So we said let's develop that channel and show what we can do.

So we are in off-road as I said...so that means Baja, Lucas Oil Trophy Trucks, Nitro- Boats, WORCS, Best in the Desert, Supercross, Motocross, GNCC.... which many of you might not have heard of. But it basically the highest levels of Off-Road Racing in USA. We do Cars, Trucks, UTVs, Motorcycles etc...

So Robby Gordon is big name in off-road, and he's running our batteries and got the Pole position the last 2 years running for the Baja 1000 though he didn't win. Please realize we are starting 900 Horse power, High Compression V8 motors that needs a 15 to 20 second priming to get them started. Then these Vehicles go roughly 1000 miles over the next 24hours on the roughest terrain the world.. That include team Honda, and Yamaha and Kawasaki also in the bikes.

Then we also do bikes and UTVs and ATVs big time in the WORCS, and GNCC, and we have Walker Fowler (Team Yamaha) who is the Champion of GNCC ATV Racing the last 3 year every year running our stuff without a failure. Then Chad Weien (Team Yamaha) 7 time Champion in ATVMX. Now keep in mind GNCC is also massivly muddy with river crossings, and WORCS is open desert with Sand whoops for miles. So this is not a road circuit with some Road and Engine Vibration... this is massive hits and slams and vibration that wreaks so much havoc that only some of the vehicles can finish the races because it is so hard on the vehicles. That is why I jokingly called Street as "sissy" stuff.

Then we have the Nitrochondriac team using us in Boat Racing... cool video if you don't know about top fuel hydros https://www.youtube.com/watch?v=JxJgzNtE6t8

We do Freestyle Motocross... we are in most all those bikes... Ronnie Renner multi-time X-Games Gold Medalist, and Destin Cantrell you can see this video of what they do and why they need a lightweight battery. https://www.youtube.com/watch?v=1xtRPzLpYi0

So it sort of relative to the channel your in, sure you may not have heard of us... it's quite understandable, but don't think that not having heard of us is relative to what we do or how good our product is. We actually brought the first mini Jump Starters to market in 2013. Our MICRO-START XP-10 was rated "Best Rated Jump Starter" by Consumer Reports. We've been around since 2010 and all we do is Lithium Products. But we are now here focusing on the Street side now so we will soon be getting the brand better known over here.

You can also learn more by going over to the GT3 forum... we had a 25page thread going on over there during a group buy a couple months ago.

I would love to have that data for your specific car so we can compare it to others. We keep a log of many cars who are using certain batteries in certain models, so we can better inform Customers of the real life Parasitic drain we are experiencing for specific Cars. Is yours track and street? Or mainly Street? Or just track? Is it a 996 Turbo like this forum we are in?
