Has none of you heard about a battery delete? Put a distro block on a piece of wood for Christ sakes, put a cap bank in place of the factory battery, or just run a wire from alternator post to the factory power distribution (fuse box) and your 1/0 straight to the rear and call it a day. No batteries should honestly live under the hood, do you know how much longer even LA lives when in the trunk or under the backseat (GM is the only one I know that did this)?

But I see you not working.... Nice attempt though. On a 2 year old thread to boot.


The following is for future readers to wrap this up.
FYI RED headway is 15C discharge 180A to 200A rating depending where you look. The blue cells are NOT amperage cells and are much less(probably 5-6 as stated above.) Red Headway is fine but make sure you keep an eye on them and break them down every once in a while. Ideally test and match up cells. At minimum balance them together then let them rest and then voltage match the best you can. Each cell ran parallel alike. Cells will destroy their neighboring cells first before moving to the next group. Very easy to find a bad egg. Run a balancer and a monitor (the ~$10 RC monitors are just fine)

If doing a competition or going to a meet and doing demos all day it never hurts to do a quick check on each row at least, this is a general statement with lithium ( d4s, limitless, titan and the like guys excluded, goodluck to you, you've already been screwed!)

Headway is a good beginner DIY introduction into Lithium. 32AH is minimum but I strongly suggest a 48AH bank at least. (This is minimum! The actual amount varies but 1p/500w is conservative 1p/1000w if you just commute.) And yes headway can be mixed with AGM just fine, you should see a resting voltage at around 12.9 to 13.1 (pay attention to this and if it changes from normal time to open the bank.)

I also suggest a cap bank on any system last in line to the amp/s to take the hit and soften the blow on your batteries no matter what. Not to mention the caps alone help tremendously and play well with all batteries. (No, I'm not talking about the stupid concrete filled gimmick stiffener caps, only thing they are good for is a voltage meter and even still!)

Lithium takes dedication and maintenance. That is what I'm afraid to witness with all these EVs but neither here nor there.

Godspeed

Keep trying kid. The thread is barely over a year old. I don't want to do a battery delete and I don't have to do a battery delete. My system works just fine, competes very well, and gives great demos. I replied to you. Btw, I don't have a trunk or backseat. Keep working kid.

I applaud you sir, well written, very informative and accurate! Well played!

I have this one as well and it has been very useful. Would recommend if you need a versatile battery charger/small power supply.

That’s a 6s balancer but will still work with 4s as long as the last 2 positives are not used.

14.6 is max charge for headway. 3.65 volts per cell. There should not be any voltage drop from your alternator wiring to battery so 14.8 is too high.
