Stake cheese caramelised onion. Don’t want to be distracted by a rumbling tummy when playing with battery’s this powerful

Yeah battery tabs is the way to go.

You call that cheese?

I thought it was straight macaroni and you were overcompensating for your gayness.

Cell voltages checked and cell layout decided…

Damn that trampa looks nice with the 9inch wheels. Can’t wait to do a full discharge test on this battery :rofl:

I’m assembling my first battery pack, and I really REALLY don’t want to mess it up. Its a 10s4p with Samsung Q30, DieBieMS and made out of the NESE 4p modules. I’m confused about the balance wires where to insert them both battery side and on the DieBieMS (C1-CX and GND) Here is a picture of the pack and I also added the picture of the balance lead plug on the DieBieMS.
Would like confirmation if my series configuration is 100% correct I marked that in blue on the picture. (I am very anxious about blowing this up)

Also would like to know how to configure the DieBieMS software.

I have been reading through a few posts on both forums and they tend to get very messy and confusing to read through :confused:

Have you checked out the manual yet?

No, I didn’t know it was out yet. Ill give it a read! thanks.

When using the monsterbox in a 2 x 6s configuration is there any particular XT90 port that is the designated charge port?

Doesnt the monster box have the xt90s labelled vesc and charge?

Na they are identical, the only difference between them is how the wires connect to the battery. I just ended up taking the gamble based on what I found in some of Trampas instructional videos. Currently charging away, just another 6 or so hours…

Plenty of time to look at a booster lol.

By the looks of it you have one of the earlya DieBieMS

GND-S1-(battery-)
C1=S1+
C2=S2+
C3=S3+
C4=S4+
C5=S5+
C6=S6+
C7=S7+
C8=S8+
C9=S9+
C10=S10+ (battery+)

The later gen DieBieMS were labelled a bit differently witch is were you confusion might be

C0- =S1-(battry-)
C0+=S1+
C1=S2+
C2=S3+
C3=S4+
C4=S5+
C5=S6+
C6=S7+
C7=S8+
C8=S9+
C9=S10+ (battry+)

Other things to think about are you adding Temperature sensors to you battry. (100kOhm at 25C Thermisteres are recommended type C)

I have no idea what a type C is if some one with more knolage can educate me be much Appreciated.

Do you want the VESC to be able to power up the battry (used for push to start) this involves a extra cable on the can been attached to the VESC 5v

Do you want a button to power up
(Personally I shorted out the Unity button so Unity was Permanently on and used the DieBieMS anti spark)

Do you want a Sreen on the board
Simple conect like dot to dot just follow the labels (hint there not in the same order)

Yeah I am going to add a temp sensor ASAP, where would you recommend putting it/them? just near the centre of the pack?

No I doubt I would use push to start, but would that be connected via the CAN on both the FSESC and DieBieMS to have that option?

(Personally I shorted out the Unity button so Unity was Permanently on and used the DieBieMS anti spark)

I have the FSESC6.6 Simplify Version so I plan to use the DieBieMS powerbutton.

One other question, what about regenerative braking is it OK to have that enabled on the FSESC with the DieBieMS? And does that require any additional wiring?

yeah, 9" with the gear drive is mandatory

Yellow are top connection(seen from this angle)
Purple are bottom connections(not seen from this angle
I need confirmation that I’m not derping badly

You are better off welding series connections from each individual cell… like this


… just maybe dont need as many :joy:

damn, thats alot of clips
ive yet to decide how much im gonna focus on series connections, i wish i had a sheet of nickel that i can cut down, would have made everything much easier and cleaner

Yeah it would. The connections you’ve drawn though will have way too much series current running through your parallel strips.

I would use at least one strip between every cell

2 Likes

will do, maybe 2 strips each cell if i have the time, i need this finished by monday and i have my kids this weekend

Hey, looking good, you are asking the right questions. One thing I strive for when designing a pack is that each cell has the same total length of lead in the + and(-) direction
