  1. Will do the wire brush and tap and die. Some of the nuts were extremely difficult to remove, and I specifically used stainless steel ones after the first time the batteries died, and they still rusted. My problem is that I'm in Europe so cannot really find any LTO chargers and getting a load tester just for this one task is a bit beyond my budget right now. I can only charge these when they're together as a bank, either with my AGM charger or on the car, and they never had more than 15 volts in them. At most 14.8-14.9 (so less than 2.5 per cell, unless some of them overcharge a bit, but then the balancer will slowly take care of that). Maybe in the future I will buy a load tester. I could just do a burp and check the voltage sag after I put back the 12 best ones with the lowest internal resistance. And most auto shops around here really don't know how to deal with this stuff so I'm kinda on my own. I saw a video of some Russian dudes load testing some of these with a resistance in a bucket of water but that's too sketchy for me to try 😅 This meter seems pretty accurate. Touching the probes together gives me a 0.03 milliohm value so almost 0. (touching them the other way around gave me an error so I think they have a polarity cause there are 2 tips on each probe). Did not check all the cells yet but the ones I did check, I did give them a clean with WD40 so I'll say I touched the probe to a clean part of the posts. And it's the same meter used in screenshots on aliexpress where they sell some of these LTO cells. If that counts for anything.
  2. Hi guys. Trying to troubleshoot some LTO issues. These batteries are 5 and a half year old and have been in the spare tire well. This is an area where I couldn't check regularly cause the subs were right on top and to check it I had to disassemble everything. The car leaks water in the spare wheel well so not sure if that was the cause of the problem. There are 24 cells in total grouped in 2 banks. One day the batts just died. I was reading 1.2 volts from the whole bank instead of 14 ish. So 1.2 combined. Around 0.2 each some of them a bit better or worse. Didn't think they could recover from that. First time it happened I took them out and charged them (with an AGM charger cause I don't have a lithium one) and they seemed fine. Put them back and they worked fine for months. Also changed the balancers to brand new Heltec ones. The 2nd time I also had a parasitic drain. The fuel pump relay was stuck On, so the pump didn't turn off when I removed the keys from the ignition. No idea how long that was happening but they died again and same symptoms. Don't know if they died by coincidence or if the fuel pump just discharged them. 1.2 volts from the whole bank. Removed them, charged them back. Seem to work fine but the water leak was worse this time and I can see some of the signs. Some of the posts are kinda missing a tiny chunk of the aluminum. I'm wondering if this is corrosion or I had a short. There is also this white dust everywhere on the posts. Either the corroded aluminum or lithium titanate powder from the inside? Bought a resistance meter and most of them are around 0.30 milliohms. So far I found one that's at 42 milliohms so pretty sure that one is a goner. Resistance is supposed to be around 0.20 when they're new as far as I know. Anyone had similar issues with LTO? Trying to understand exactly what happened. They've been around for some time now. And these are more than 5 years old. I'm thinking I can check the resistance of all of them and choose the best 12 cells I got and put them back into a new location where there's no water leak and see if that works for a while. Any input is appreciated. Thanks!
  3. I platinumed it on PS4. Good game. I've also played Heavy Rain and Beyond Two Souls made by the same company (lead by David Cage). Also piewdiepie is currently doing a Let's Play on this game. He was forced by the fans. But don't watch it if you don't want spoilers.
  4. This is a full bridge amplifier? As in "brazilian" full bridge?

  6. Today's episode of Dragon Ball Super was amazing! Awesome new transformation for Goku.

  7. I don't envy the guy that has to go through all those comments to sort them out for the raffle.

      I presume they'll be using some sort of script/other data they're able to collect via the site.

      Would be good but I don't think they have that. I think they have to do it manually, and there are more than 1600 posts...

      It could be done very easily.  Draw a 0 or 1 for the first digit.  Then make three more drawings with all ten digits.  Those 4 drawn digits will create a post number.

  8. That's because today's music is offensive. They didn't always use to sing about drugs, ho's, stuff like that... I wish I was alive back then.actually if you listen to it they did. Some of that shit is just as bad if not worse if you listen close enough LOLHell yeah it is, they just didn't come right out and say it like nowadays but they most certainly sang about drug use and violence. and free love aka fucking everything in site without a care in the world.... just sayin'. Ok, I stand corrected.

Some of that shit is just as bad if not worse if you listen close enough LOL When I'm near that girl that I love best My heart beats so it scares me to death! Well she touched my hand what a chill I got Her lips are like a volcano when it's hot I'm proud to say that she's my buttercup I'm in love I'm all shook up Mm mm mm, mm, yay, yay, yay There's nothing offensive about that. Listen to Ying Yang Twins - Pull My Hair. Now that's offensive...

  11. It's pretty awesome of you guys to have so many giveaways. Good luck to everyone who enters. Second Skin FTW!
  12. Nice explanation for the different materials. Most guys think that just by sticking some cld to their doors they eliminate outside noise, which is not the case. Also for cld to work, you don't need full coverage, you need at least 30% coverage in the central parts of the panel to control resonance. However, for mlv to work, 100% coverage is needed and all the seams must be sealed with aluminum foil tape.
