Lightweight battery

[Ghost_M3]

Looking to purchase a lightweight battery and I’ve found two that I like. Has anyone used any of the following?

I like the lite blox because of the kill switch feature.

No experience with either model you listed. We have a small lithium battery on the track car. It has sn undervolt switch to avoid leaving you stranded. Its on the battery itself. For a street car I would recommend a remote switch to the drivers cockpit area so you're not digging in the trunk to start the car.

If your open to suggestions. Anti gravity if you have the money. 12lbs. I have the H7 60Ah, ive never had a single issue and the auto turnoff feature is great. Also the ability to check voltage with the app via Bluetooth.

I've been running a Brail GU1R for over 4 years now, and not had as single issue. That said, I do put it on a maintainer if I'm parking the car for more than a week or two. That said, I also do that on the stock battery M5 and M3 wagon, soo....

When it ages/cycles out, I intend to replace it with something with an automatic cutoff feature, as that does seem like nice peace of mind. But, doesn't seem like it's worth replacing a wear item preemptively for that functionality.

Thank you everyone for the advice. I’m looking to cut the most weight from the car and I like features that allow me to see voltage of the car so I might go with the anti gravity but the lite blox has some features that I like. My car does not have raiding or other features that consume a lot of power so I’m not worried about a lithium battery. My battery is about four years old and I believe I’ll need to replace it soon.

Ive had the Braille GU1r for 4.5 years now with no issues. It is 4.5# i believe. I also have a small 4 channel stereo amp that it powers, and the car sits for long periods sometimes. In the longer periods, I use their trickle charger to keep it fresh.

I'm planning to go with an Anti-Gravity Li-Ion battery when my CSL battery goes out. I think they're around $700 and weigh about 8-10lbs and are a stock battery size, so easy install.

This has been 5 years now, curious what battery you are running now? I need to replace my battery eventually, its from 2018 hahaha so I want to get something good and light. I will have it on a tender for the most part since its always garage kept in a climate controlled environment and will be out on track days or cruising.

Still have radio and speakers but thats it.

Still running the same Braille GU1R-- over a decade old now! Still has never given me a single issue.

Not bad for <6 lbs.

They no longer sell it for some reason. You have full radio?

Im going to try and find an exact replacement that Braille has now and I will get the same thing knowing you got no issues. A DECADE!!!

I do not have a full radio. Xtrons head unit (for factory looking wireless carplay) and front door speakers, and that's it. Took ~45 lbs of stereo modules/wiring/brackets/speakers out of my car!

ok my rear speakers are on their way out. All i have is a EONON, I wil k eep front doors (maybe, the damn door handle is in my way when turning will see if a smaller diameter wheel will fix that since my arms are short) and I will remove the rear deck lid or sub. No CD player etc

Also do you recall, this is off topic if I need to rewire door airbag if I remove doors?

And I am guessing you have LIPO battery tender?

Not sure what you're asking on the rewiring of door airbags.

I do have a CTEK LiPo tender. But, I only use if if I'm not going to be driving the car for 2+ weeks or so, which pretty much just means over winters.

Ignore door airbags Ill research that myself. But sounds good on battery. I will get the new equivalent. Which is a Braille Performance GreenLite Lithium-ION Battery - G30 going for $530, Is that roughly what you paid for your battery back then?
