| Description_EXT | BMS Master Module for VCU |
| Description_MKT | The AEM Battery Management System (BMS-18) is comprised of three components: |
| Description_MKT | 1. VCU |
| Description_MKT | 2. BMS-18 Master |
| Description_MKT | 3. BMS-18 Satellite(s) |
| Description_MKT | The BMS is implemented as two different Module types: the BMS Master and the BMS Satellite. Each Module is capable of measuring up to 18 cells and 3 temperatures (thermistors) but the Master also contains the CAN communication interface and J1772 charging specific connections needed for each battery pack. |
| Description_MKT | The VCU communicates with the BMS via the Master Module and all battery packs need at least one Master unit. The Satellites expand the capability of the Master by an additional 18 cells and 3 thermistors per additional Satellite connected. The Satellite Modules are connected to their Master via a high-speed serial interface (isoSPI) that allows additional units to be daisy chained together, adding as many Satellites as necessary for the battery pack configuration. |

Nice suit
This 5 piece set is really nice
Pros:
fits true to sz which allows it to sit nicely
The pants have adjustable waist bands
The color is as described
Material/fabric is not that great but will do (select a neutral color which can prevent it from looking cheap)
Perfect for a growing boy who will need another one soon
Cons:
The tie is little short and is a non adjustable elastic
the handkerchief/pocket square does not fit in the faux pocket.
If you want an elevated look - wear with a different tie, thicker fabric white shirt and nice shoes

Order a sewing machine too
Color: Light Champagne, Size: 14, Color: Light Champagne, Size: 14
This suit had me questioning whether the manufacturer had ever actually seen a human child before. The pants were SO long — like they were tailored for a 9-year-old with 100 feet of shin. 😂 I had to hem them significantly just to make them wearable for a normal boy.
The bow tie was also a letdown. Ours may have arrived defective, but it only seemed to have one hook with nowhere for it to actually attach, so we ended up improvising with the fabric loop. Not exactly the polished wedding-ready moment I was hoping for.
The shirt was probably the highlight. It has a subtle textured pattern that makes it feel a little more unique than a standard dress shirt, which I appreciated. Unfortunately, the fabric itself is stiff and not particularly comfortable. Overall, the whole set feels pretty cheap quality-wise.
BUT… he’s 9. He’ll outgrow it before the next wedding invitation hits the mailbox anyway. 😂 For one day of looking like a dashing young gentleman instead of a tiny tornado in sweatpants, it got the job done. Just definitely not something I’d recommend for peak summer wedding season unless your child enjoys marinating in polyester.

Loved it

Pretty good fit on my son. I'd say it's true to size. He looked great for his guitar recital.

Happy Customer

I really loved the way my son looked in this suit, pants were a bit baggy and big on the waist but I’m glad it was adjustable, the length was perfect.
