TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Thanks!

You Gen 2 guys seems to have all the best options available for gauge mounting for sure!

LOL

 

Not here to provide info. Just to vent.

You boys EVER buy a lithium battery for your truck, RV, solar, or boat, you make triple sure that they come with a BMS. I just lost one due to the lack of this. and it was a really high capacity 12 volt too. 138 AH.

 

what brand?? I didn’t think any came without them.

 

Battery management system. It ensures the lithium chemical compound charges appropriately for the ambient temp, also manages discharge rates.

 

Yep looked it up. But don’t see them built into the battery in my real quick search

 

Valence XP series (I have a U27-12). I thought this as well, but apparently, I was wrong. They sell them without an internal BMS, only external which is booku bucks. Their RT series does, however, and somehow they are cheaper in price than these with far less capable output as well and I just lost one because (I'm pretty sure) of high ambient temperatures.

So now I make lemonade out of lemons using the original singular same version lithium I had prior to getting this one.

 

I run down the pro touring bass boat guys for their starter lithium batteries. They get new boats and batteries every year. I run a completely divorced high capacity battle born off three 100 watt panels with a controller and inverter for other junk.

 

That's not a bad idea actually. Especially since I'm constantly around hardcore fisherman and run into pros every so often as well when they are on their tournaments.

I figured out my rear hatch setup for the boat. Three batteries still, now all three will serve different purposes, however. One will run the main motor exclusively. A 12V Group 24 80AH AGM cranker for the Mercury. A 12V Group 27 138AH lithium (my remaining Valence battery) for all of the boat electronics, livewell, bilge, Navionics, Panoptix/ transducer sonars, charging. Then finally a soon to be dedicated 24V Group 31 60AH lithium for my Minn Kota 80lb Troller. No more playing with the main motor to keep the AGM charged after running all of the electronics I highlighted above throughout the day and each major section of it will have its own dedicated power source. I think at this point the only thing which I could really improve would be charging efficiency via a solar panel, but now that should be a non issue given the dedicated section exclusive power sources I'll have on it.

Lemonade after all.

 

Since you are talking about your boat, I have a quick boat question for you -

I assume you will run 3 battery chargers (when not in the water). Do you plan to have those mounted in the boat, or will you have a custom wiring harness to attach to the batteries?

I ask, because I am in the market for a boat very similar to yours.

Thanks - back to supercharger talk...

 

No. I plan to run 2 on-board chargers. Due to the fact that the battery I just got is very custom and basically a two-in-one sort of design, I am limited to "type of" chargers as well.

The one which will be exclusive to the 24 volt battery is a Victron Blue Smart 24V 8 amp IP65 battery charger. They are known for their quality in the lithium battery arena.

For the remaining two 12 volt dissimilar AGM/Lithium batteries I will be using a Noco Genius 2X5 which has its own battery type selectable independent charging channels. Both will be handled and charged with 5 amp charging outputs.

Believe it or not, all of the harnesses in the rear hatch are all OE still and the only thing I have ever done back there is lengthen one of the ground wires for the troller motor. I did, however, rearrange the entire setup to work the way I specifically wanted it to. As it originally came super barebones and very poorly thought out like so:



As of this current date, everything has been rearranged and larger units across the board including the fuel tank size have been retrofitted and a better balance of weight distribution and space has been optimized. As fuel runs down, the weight goes down but it does so in such a fashion that keeps the weight distributed evenly back there preventing what would be the equal to the "taco lean." This picture reflects the current layout and wiring harness rerouting prior to the AGM replacement of the black interstate battery (I run an X2Power group 34M AGM now) but it is not going to actually be wired like this at all anymore on the left side (lithium battery side). These pictures I actually took prior to hooking everything up properly, it was more just to showcase the new better thought out layout.





So now you guys see where a lot of my energies and attention has been diverted to for the last few months. I shouldn't be under the hood or beneath vehicles much, if at all anymore so I've been forced to invest my time and efforts to "easier to access" designs these days. I leave the truck modding to my old work and my old co workers now unfortunately, at least until I can reach a proper level of recovery.

 

Thanks.

Your new arrangement is much nicer.

You definitely don't want "Taco Lean" on your boat! LOL

 

Thank you! It keeps the weight distribution much more even back there and in general I feel like. The AGM weighs about 50.5 lbs on the right while both Lithiums weigh 73 lbs. The tank when full weighs about 79 lbs and keeps the entire hull floating nice and evenly over the water. When I'm driving it, my 150lbs doesn't feel like it forces the entire thing to track biased right whatsoever.

 

Is that because the police cant catch you in your other cars Steve?

 

So, I have one. The BMS is built into the battery. The price is about $2200 if I recall. But thats what you get for a factory bmw part. Lol!
Anti gravity makes lithium batteries for the auto side as well. They have the BMS built in and a switch if the voltage gets to low it disconnects the battery internally. They have a reset button on the top of that happens.

I would run one of these antigravity batteries
"LITHIUM BATTERIES, MICRO-STARTS – Antigravity Batteries" https://antigravitybatteries.com

 

Oddly enough, I find it ironic that every last one of these companies who "make their own batteries" whether it be from the US, Germany, Italy, or anywhere else, all source the actual heart of the power source, the cells, straight from China.

That's right boys, even our beloved Prius and Tesla use cells that are all made in China.

Going back to this, I have seen them many times before and do not question their builds, due to space constraints and the specificity of my own build, I am limited in space as to what I can run, the largest amount of space being that the equal to a 31 group battery.

 

Look at their site. I thought I seen a group 31 equivalent. Search though all they off and see what will fit.

 

I already bought my battery so it's sort of too late. Lol.

As for cheaper Lithiums on the market, they are a dime a dozen and if you YouTube "Solar with Will Prowse" he does some serious in depth reviews of many of the current offerings on the market today. You'd be surprised the quality of the cheaper offerings today, while yes, some fall on their face and fail the inspection/ testing, others pass both sides of that spectrum in quite a stellar fashion for a cheap price.

Antigravity batteries are DEFINITELY the super expensive side of that. Also, I didn't remember seeing a 31 series 24 volt option which is what broke the end of that search for me.

 

So is a 24V battery preferred over 2 12V batteries wiring in series?

Or is a 24V battery really just a big case around the guts of 2 12V ones?

 

It's a big case around the guts of 2 12 volt ones, however, the guts are constructed intelligently and to work in harmony with each other and are internally wired in such a way to do so. Where as wiring two 12s in series externally is more of an afterthought and too many external factors due to the fact that they were not designed to run that way since they were stand alone units in the first place.

Apparently one Lithium 24 volt 50 AH battery is the equal to one 12 volt 100 AH battery, so the fact that I got a 60 already puts me ahead of those statsi found this post most illuminating and reading it only further re-affirmed all that I know now.
