Powder coated pedals black and added a v3 louvre fender

Very nice, particularly the back pedals. Powder coated is the Cadillac version :thumbup:

On one of my ACM's when it was totally disassembled, I used the opportunity to spray paint mine black. I really like the look.

One thing that I did that you may want to consider is to paint the pedals hangers (the parts that you can see), including the two spacers. Just use a nice flat black spray paint.

how did you powder coat them?

 

I have a craftsman powder coater  bought it for $30 bucks like 4 years ago still works like a champ. And it cures in oven or heat gun. I used heat gun. Harbor freight has them also and the powder like $5 for a pound of it

I will probably paint as powder coating makes things not fit right cause it makes it thicker.

Hello, "Hansolo", few question to your additional battery packs, if you don't mind:

1. This thing circled in red on the picture below I assume is the bms. Is this bms the one which was already present and installed in your MSX for the original battery packs, or is it some additional one you constructed yourself for the three smaller battery packs you added to the wheel, please?

2. Do you maybe know what is the exact brand, model and capacity of the original 18650 cells used for the original MSX battery packs?

3. Did you use the exactly same cells for your three additional battery packs? If not what kind of cells did you use, please?

Thank you. :efef3d5527:

1 Additional BMS (it's a BMS GW that I cut to keep that active part)

2 18650 3500mAh, I Don't know the exactly brand and model, I use Sanyo NCR18650GA 3350mAh - 10A in my extra pack

The bottom pack and the one on the other side are identical 18 cells, the one with the BMS 24 cells

"Hansolo", thank you for your help. However, since I'm not an English native speaker and by no means any kind of techie which frequently make me get lost in electronic lingo, I'm not sure here if I got you correctly on the BMS issue. So, I hope you wouldn't mind me asking again just to be sure.

it's a BMS GW

Do you mean it is some kind of Gotway BMS taken from another Gotway wheel...? Or maybe you bought it from Gotway (Kebye) as a spare part? Where exactly did you get this additional BMS from, since it is not the one already installed in you MSX for its  original battery packs?

active part

What exactly do you mean by "active part"?

Thank you in advance for the additional info; I'm really so determined to build such extra battery packs for my MSX. :efee8319ab:

But, "Hansolo", what is that whole green stuff from which you cut this bms part surrounded in yellow? Is it like an MSX's mainboard or something...? Where can I get it from? How much does it cost, if you please?

Do you think this budget equivalent would do the job...?

I use the same BMS than second link in my MS3 with extra battery 20S2P (not 3P) the others are too big!

In a MSX if if you limit yourself to a battery the BMS of second link is OK, but for a 20S3P no, not enough space.

In my MSX with 20S3P battery and GotWay BMS it's very fair.

My bms is already purchased and is arriving to my place. There is one more case I was warned about:

1. Some believe the cells of any additional sets should be assembled of the exactly same cells as are used for the original, already existing sets. And they say it applies to the brand, model, capacity. The reason is something about differences in resistances of the cells which might cause generating of some kind of leveling currents between packages which could be destructive for the cells themselves and for the whole system. What do you think about it? Should I worry about it? 

2. What is the exact brand, model and capacity of the cells originally used for the two battery packages installed in MSX 1600 Wh?

3. Finally, is it right each of the two originally battery packages in MSX have separate bms's and then are connected parallel with each other and then to the engine?

Thank you.

Hello, again, currently I'm at the stage of acquiring a set of pcs 60 18560 cells for the project described above and I face a basic problem. The Chinese seller of my MSX 1600, which I'm still waiting for, assured me in his email it features NCR18650B which are Panasonic cells. The Polish Gotway distributor on the other hand is absolutely firm it has NCR18650GA, which are Sanyo cells. Is there any way I can be sure about the exact cells brand and type in my MSX before the wheel comes to me, which for some reason is so very paramount to me? Is it ever possible some MSX units could have originally installed one and others another type of battery cells...?

The 1600wh GW has Sanyo GA cells

I personnally know NO Wheel that has  Panasonic NCR18650B cells...as These are to low amperage to use in a EUC! So the chinese seller just seams to have no clue what he is Talking about

Can't you order the 60 pcs once your wheel arrived so you are on the safe side?

As @US69 already stated i would also prefer the NCR18650GA over the NCR18650B

http://www.dampfakkus.de/akkutest.php?id=609

http://www.dampfakkus.de/akkutest.php?id=141

They have less internal resistance, higher nominal current and higher capacity!

BTW: at dampfakkus.de they are listed as panasonic batteries, too. on other sites as panasonic/sanyo ... ??

... which for some reason is so very paramount to me? 

Some "importand/interesting" reasons or just personal preferences?

Sanyo is/was bought by Panasonic (or they are Sisters, i dont know exactly) 

So the GA cells where -in the beginning when i remember correctly- also produced under the Name of Panasonic.

As said...the NCR18650B with 3400mah and 6Amp CAN not be in MSX1600 :-) The chinese seller must be totally wrong….

Guys, THANK YOU so very much. :rolleyes: To begin with, no, for some practical, much complicated, boring and totally irrelevant for the merit of this topic reasons, I cannot buy the additional cells just having the wheel first already; I do necessarily need to possess the cells before receiving the car itself. Otherwise the whole buzz about the brand and the model I induced would not be necessary and would not even exist. ;)

And then, I don't regard using the same cells as the ones already used in the original packets, for building my additional packet, as a matter of preference. Some experts explained to me other type of cells exhibiting other electrical parameters, like capacity, internal resistance and possibly some more, might and probably would not go down well with the original packets causing some kind of conflicts. An issue of "balancing" probably is at stake here, or something like this... For which reason, just to keep a peace of mind, I am so desperate to use the exactly same cells as the original ones for my additional battery pack. Does it make any sense to you...? :unsure:

One more: from each of the two original MSX 1600 Wh battery packets there are six wires going out: two thicker, red and black, with a yellow connector, and two additional thinner pairs, each pair with also black and red wires and each with black connector. I guess the thicker cables with the yellow connector are main power cords. If so, what are the two other black and red cable pairs for, please...? :confused1:

Each battery pack has a Battery Management System (BMS) circuit board. Those small cables interconnect all of the BMS circuits (the Monster has three).

The yellow connector (XT60) is the power.

The little black connector with two contacts is for charging

the little black connector with four contacts is an interconnection between BMS, if one is in error the others put themselves in protective (during the charging)

From my readings so far cell matching is very important for series configurations (https://batteryuniversity.com/learn/article/serial_and_parallel_battery_configurations). If the cells are not well matched large capacity losses can occur (https://batteryuniversity.com/index.php/learn/article/bu_803a_cell_mismatch_balancing - the graph in this article is with already aged packs!)

So for a ?third? parallel pack with it's own BMS it should not be dramatic if the used cells are not exactly the same cells, but i ...

... would go for the same calls, too (peace of mind is very important) :thumbup: Not despreately, but if easily possible. Just if the wheel has the "not so good" NCR18650B inside i'd presumably choose the NCR18650GA for the new pack :ph34r:

Guys, I know you're going to hate me this time, but listen to this: I again emailed my MSX's seller with a kind request to confirm the color of the cells in my machine and a picture of those, if possible. Now look what I got: Their answer where, the cells are GREEN and they even sent me a picture...! It clearly looks as they are indeed Panasonic NCR18650B!!! Well, I try to be a reasonable bloke but at this moment a conspiracy theory, that I bought some poor, budget, Chinese, not European or American, version of the wheel, starts haunting me... How possible all other MSXs feature red Sanyo NCR18650GA cells and my unit does not...? :unsure:

Still I suppose some people might be shipping pack with different cells.

That's strange... I rather believed all the Chinese "people" selling MSXs get these from the "Kebye" factory with battery packs already assembled and installed in the cars by their maker...:unsure:
