Man that is gonna make some real power! 1.1 gigawatts! I want a C-Max so bad man. I’m just stacking my play time coins until I can grab a set. Still liking the vids.Keep ‘em coming

Thank you I tried to mention as much as I could during video

[@tonyfoley9988]

I'm trying to do research about lithium because I'm going to need a power bank for my new setup and I've only ever used AGM. These days it's all about the lithium but I've always been scared of it. You make me feel a bit more confident about building a bank. I'll most likely be going with LIFEPO4 cells being they can be used with a AGM battery without a isolator. Great job again!

[@BIGJURAY20]

That's a great idea to do. That's exactly how i felt about lithium after using Agm for so long. If i can get comfortable enough to build a lithium bank I'm sure you can too. Best of luck with your build

Great job man appreciate every little details keep it up, Can you send me a link to where I can order those exact same cells, are those Cells 3.5v or 3.7v per cells, I will build my own one by looking at your video, so these 240Ah bank are they at 12v or 15.5 v after finish put together

[@smigletat9634]

How many volts are each of those cells individually/by themselves?

[@BIGJURAY20]

These should be between 3.7-4.2v mines are charging around 15.8v so 3.95v each cell

[@brunom1280]

Whats the highest these can be charged at? And whats the lowest the can be charged at and still used in a setup? Nice build👍

[@BIGJURAY20]

Charging is 14.8-16.8v but 16.8v is 100% State Of Charge and could shorten the lifespan of the cells. If you can maintain 15v area they should last up to 10 years depending on condition of cells used

[@brunom1280]

Hey man I have a 120 ah big cell . I'm wanting to add another 120 I could use the same compression side bars but would just need longer threaded rods right ? TIA!

[@BIGJURAY20]

Yes but if u already have one built it could interfere with spacing if u pull apart I'd run 2 120ah banks

[@BassSoLowItHZ]

@BIGJURAY20 ok thanks man. One kore question could I run a small cell and Bic cell together . They would obviously be in different banks . Just curious if the difference in discharge rate would hurt anything

[@BIGJURAY20]

@Bass so loud it HZ I have seen someone do this before and his voltage held up but i feel you wouldn't be getting the best from either bank since they have different charge and discharge rates

[@BassSoLowItHZ]

@BIGJURAY20 Alright man that's what I was curious about. Much appreciated!!

[@BIGJURAY20]

Honestly if you haven't already done so. I'd look into the smaller cells and get a good enough bank to support the needs of your system and sale the bigger cells. But then again 240ah of the large cells can still do justice but it's comparable to around 95ah of the smaller cells

[@MrMr123]

How do you charge the battery pack, What voltage

[@MrILLryder]

Clean build brother! Got a question if you don’t mind. I have a about a 6k wattage system with my 3 amps jp23v2 jp234 and jp84. 320 HOA. Under the hood I got a XSD5100 60AH. If I wanted to go LiFePo4 what would be a suitable AH bank? I bought a 20AH Ampere LiFePo4 battery already they use Grade A cells in their batteries. I was wondering if I need more. According to skyhigh car audio techs Lithium is double the power of Agm/Lead so 10Ah of lithium is like having 100ah of Agm/Lead. And LiFePo4 uses 90% of its density while Agm/lead uses 50.

[@BIGJURAY20]

Don't have much experience with lifepo4 honestly but 40ah should sustain 3k for a full system. Your 20ah should hold up ok during play much better then the 60ah agm you have

[@BIGJURAY20]

Is the battery you have ok to use for car audio?

[@MrILLryder]

@@BIGJURAY20 yes it’s safe to use with car audio. LiFePo4 is the same as headway. You just have to make sure it’s Grade A or B cells whichever company you use.
