Default Re: RS-30 lithium battery

Paulo, I've been really happy so far with the Mini/CSL H5 Bosch. 32lbs yes, but with plenty of CAs and reserve time for a street car (mine having a light stereo system). Good way to drop a little weight, but not need to worry about anything else (unless the car sits a long time, then tender). Only $165 too.

I have had zero negative repercussions of running the Braille, both daily, and after it had sat for several months without driving. It has been solid and issue free.
Haha that’s what I figured. I keep hearing all these lithium battery cons (which I’m fully aware of), yet I’m specifically asking about that RS-30 battery with the on/off feature. These negative experiences will be negligeble with this battery IF it does work as it advertises. I should’ve made my original post clear.

From what Ive gathered here, hell, practically the entire internet no one has tried this RS-30 yet. I have no problem dropping $800 on a lightweight battery with these features, but it better work.

thanks man, I’ve had my eye on them. Once my battery starts to show signs, I’ll get a mini battery. Unless of course a review pops up on these RS-30’s.

I’m confident by the end of this year I’ll be below 3,300lbs with full/stock interior. This is why this battery got me all excited

Unless Iím missing something, the battery prevents parasitic or idle current draws from draining the battery below a point that it canít start the car. This means it will disconnect and no longer support idle current draw.

I donít see how your car doesnít lose all of its memory functions like time, trip miles, etc every time this happens. Unless Iím missing something...

Lithium batteries have much poorer performance in cold weather. Unless theyíve engineered something special then I would imagine this battery would suffer the same capacity degradation.

I used one of their 16 cell batteries in my M3, about as big as my fist and 2.9 lbs. Never failed me however i did have it on a trickle charge when the car sat longer than a week.

The ATX-20 has restart. Haven't need to use it yet.

Incredible. Any specific bracket to mount/secure it?

Default Re: RS-30 lithium battery

I've been running my 6 lb lithium braille GU1R for 3 years now without issue. I discharged it once in that time, but it has an auto disconnect feature to prevent full draining. No button to get a start after, though-- that's a neat trick on this one!

I do put it on the trickle charger if I'm parking the car for more than a couple weeks (winter, longer projects).

This battery seems interesting-- hopefully by time I next need a battery there will be some reviews of it up!

If price isn't an issue, then this seems like the ultimate battery.
I must say, that my $99.95 Deka EXT20L has given me zero issues. Weight is ~15lbs and I don't daily my car, so it frequently sits for a week or two. Once I go over 10 days I just throw the charger on. Really not a big deal for $600 less.

Yes, auto disconnect and auto start button feature on the battery itself! It does seem like a win win solution for those wanting to shed weight, regardless of their reason.

I personally don’t want a lithium battery without these features.
