Merry Christmas, Bassheads. My old cmax dropped to 7v because I left my winkie on working construction. Had to buy 1.5 amp slow charger brought it back to life buddy used it for 2 years now another guy has it still running. As long as the bank stays balanced while charging your good and didn't loose a cell. Always check voltage before firing up. Slow charge it to 15 before starting.🤙
Looks like I'm not the only one working on thier system today . I spent 5 hrs cramped in my yukon adding layers to my wall . Came out decent so far my present for myself a box of screws and wood ha!
Living in Iowa I pull my lithium for winter. early winter and spring temperatures can be in the 50s during the day and teens at night. the bars on the lithium condensate which can cause oxidization. I don't want to take a chance on connection problems caused form that even using Noalox on all connections. There is also the 2 weeks of below temperatures that we normally get.
I've always been concerned by the high parasitic drain on your vehicles. An amplifier draws almost no current when it's turned off and a vehicle almost draws no current when off. Something seems strange that you have a high enough parasitic drain to affect those giant batteries within just 1 or 2 weeks. If maybe the interior lights were left on by accident, that would make sense. I'd swap all the interior bulbs out for led's just to minimize their current consumption. If the balancers are drawing a lot of current, then id replace those with newer units that have a much lower parasitic draw.
I was doing research this past week cuz I was considering switching over to lithium myself and I had found a lithium battery that I was interested in that was fairly cheap and run across a RUclips channel that did a tear down on said battery while watching some of his other videos he mentioned something about alternators not playing well with lithium and went on to explain that it is better to run lithium in conjunction with a lead acid to save your alternator in circumstances where the lithium Falls in voltage. When I saw that video it kind of scared me away from lithium and made me decide to just stay with AGM especially considering my smaller system wattage of only around 3 - 5000 Watts
Seen that video too and almost scared me away and then decided to go lithium anyways and everything I was hearing about how bad it is for electrical systems went away. I also would not run lead acid with lithium because it was draining my lithium due to the lead battery. I built my battery bank with headway cells which also has not gave me any issues at almost a year in now with a JS alternator charging them. Im running a 96ah headway bank and a 320 JS alternator with a AGM for the vehicle side battery. Taramps 8K for subs and a smaller 1k amp for mids and highs and a epicenter all on the lithium side. Only issues I have had is below freezing the lithium gets slower to charge and discharges fast but the alternator does it's regulation through the PCM and not seen over a 14.0 charge yet below freezing. I plan on wiring up the external regulator this spring. It's already installed just not hooked up yet.
@jtbuilds9176 the video I watched he was talking about using something called a bank manager saying that it lets you use both your lead acid and lithium together in a hybrid bank is what he called it what I told him is that due to the special situation surrounding my system in my car I didn't really want to run more than one battery. Basically the situation is I was forced to use a standalone ecu to control my motor due to it being a Japanese only motor and the not having easy access to a factory ECU. The creators of the ECU that I'm running told me it's not advisable to have an aftermarket sound system in the car because the ECU is sensitive to voltage drop. So as a solution I've come up with running two completely separate electrical systems with the factory alternator controlling the ECU and everything to do with running the car. And my separate second electrical system using my 240 amp alternator from us alternators running back to a second battery that is specifically used just for the stereo system. With both weight and space being a issue I thought lithium might be a good way to go for both batteries however the thought of potentially ruining one or both of my alternators because of a lithium battery falling below a specified voltage and makes me hesitant to do anything lithium and instead go with a AGM which is still more powerful than lead acid and less problematic than lithium although still really heavy and quite large
@KrustyPickles who TF is this clown from this bs video you speak of? Lithium wont damage an alternator. Agm is not less problematic than lithium if you know wtf you are doing. Agm is inefficient compared to lithium and in no aspect is it better than lithium
It's a bench power supply. Get one that can do at least 18 or 20 volts. Then the highest amperage you can. A 20A charger will work faster than a 10A. So if speed is important, try to get a higher amperage.
Ive set cmax on fire you got lucky . It gets ugly and does not go out . I wont run it anymore . Easy to talk about you dont wanna play it will take your car almost took my house
The common misconception is people still to this day think an alternator is meant to charge a battery. An alternator by design is to supplement an electrical load that is being placed on the system. So running the battery extremely low is not only bad for the battery but it is also bad for the alternator because now the alternator has to supply as much current as possible to try and charge the battery, the bigger the battery the longer the alternator will supply as much current as it can to said battery. Now you got an alternator that will get extremely hot. As far as lithium batteries are concerned I try and tell people that the C rating is not constant across the cells Voltage range. If the cell voltage is within it's nominal range than the cell C rating applies and the cell can supply and receive it's maximum current it is designed for. Once you start running the cell outside of it's nominal range then all bet's are off and the C rating decreases. Nominal voltage=cells maximum C rating. Higher or lower than nominal voltage= cells maximum C rating goes down. Long story short, never overcharge and never charge a lithium Cell that is well below nominal voltage with the same current you would if the cell was at it's nominal voltage. This is why having a Benchtop power supply is so important so you can get the amperage really low on a weak/dead Lithium battery.
Bro let me ask you in regards to you compression. I don’t care what you think you can find on this planet that can compress the lithium and prevent the battery from swelling. You must understand that the swelling is happening on an atomic level!!!! Nothing we compress with is going to strong that mofo from blowing up or such 😊
@ didnt you just say is the vent they ain’t no good ? I’m not trying to be a smart ass just trying to get this straight. Have you had batteries show signs of venting that didn’t appear to have swelled up possibly because they were clamped by metal ? Hey and what you said about grandmas house after she passed away the family fell apart…I know the feeling that happened in our house too never been the same ever since and she would always say when I’m gone yall going to chew each other out and never get together 😢

Was working on my rear door panels...contour the panels..fiberglass to fit some 8" RF pros..
Merry Christmas Jerry and Deb.
Hope you guys have a very Merry Christmas, and the best sushi meal ever 🍣🍣🍤
Merry Xmas Jerry and Deb.
Marry Christmas
Merry Christmas sir
I have a 100 balance on my sodium and it has been great
Merry Christmas bro
Merry Christmas everyone.

Tell her to always check her voltage before starting the car
I’m in new York my headway cell don’t give me any trouble
5 amp for low voltage when charging cmax
Have yall ever metered the blazer?
Have you looked into scib? Would love to see you switching from cmax to scib
Why did you start the car tho knowing it was low? Were u unaware of the voltage being that low?
Yes she didn’t pay attention to volt meter til it was too late
Luckily the fusing protected it from a mishaps

Who was this? That dude is a fuckin idiot. Agm can't compare to lithium in any comparison.

@jtbuilds9176 where is this video? People who put out misinformation like that need called out for their bs.

Whats that charger name and where did u buy it bro😁

Exactly why i stay away from lithium, its too much for my brain to fathom 😂😂
Run a x2 power run and move them rear fuses. Also I don't like lithium because its not forgiving at all.
Not forgiving? Way more versatile than agm. You have no clue
Bro let me ask you in regards to you compression. I don’t care what you think you can find on this planet that can compress the lithium and prevent the battery from swelling. You must understand that the swelling is happening on an atomic level!!!! Nothing we compress with is going to strong that mofo from blowing up or such 😊
I don’t compress shit is what I’m saying lol
Proper compression will stop swelling and cause cells to properly vent as intended
@ didnt you just say is the vent they ain’t no good ? I’m not trying to be a smart ass just trying to get this straight. Have you had batteries show signs of venting that didn’t appear to have swelled up possibly because they were clamped by metal ?
Hey and what you said about grandmas house after she passed away the family fell apart…I know the feeling that happened in our house too never been the same ever since and she would always say when I’m gone yall going to chew each other out and never get together 😢
