I don't think it is as bad as you first think, each battery pack will be 8s4p a group of 4p cells can be thought of for all intensive purposes as a single cell with 4 times the current capacity of just one cell, so if a single cell starts to degrade and develop higher resistance it effectively reduces the available current through the whole system and thereby a total voltage drop. at some point the firmware should recognize this and trigger the alarm as per usual, the same would apply if the a cell becomes disconnected via failure of a nickel strip or the spot welds break due to vibration, the available current will be reduced to what the remaining 3 cells can supply. In the case of a cell shorting all the current will try to flow through that one cell result is massive heat and fire, this is what a good bms protects against of course this apply's to either parallel or in series packs, so in the end I do not think it will make much difference as long as you notice the drop in power and check the batteries for problems . btw I have seen a fire just as fierce from a punctured 4s lipo battery which is only 16.8v it's the chemistry that ignites with the air

Thanks, good teardown vid! If this is how Gotway is planning to do "134V", it's a solid pass on all such designs for me. This is basically one big series pack, no parallel to share the load, every cell has to bear higher amp load and suffer deeper voltage sag under load, due to the lack of true parallel-ing. Plus series chaining at that battery aggregator board of MR30(?) MR60(?) connectors introduces many more points of failure. Please do a video of Afeez's 134V RS to see if they're doing the same "134V" board aggregation of 4 ~33.6V packs.

That's not true that each cell will bear a higher current load. Each *_pack_* will bear a higher load than parallel packs would, but the series pack still spreads the current across 4 parallel cell groups (the Master's packs are 8S4P, where 4 8S4P packs in series yields the 32S4P 134.4V configuration). I don't care what Dr. Lewin says, Kirchhoff's law holds 😂 That said, I'm not sure what the degradation of a bad cell looks like in this configuration, and I don't know how the parallel groups are connected inside the new packs. Assuming that the other Begode batteries don't just completely disconnect during a "failure," this new battery configuration would yield a similar situation where a failed cell group causes the others to "pick up the slack." Still a dangerous situation either way that would need to be addressed with urgency. The points of failure at the series connections are certainly something to keep an eye on - definitely check those solder joints. Similarly, a cable failure would be a complete system failure.

@@redfoxdude Eh, I don't see your first point. I'm fine if I'm proven wrong, always good to learn something new, but then your explanation is lacking. This wheel is rated as an operation 134V 32S, ie. true parallel count is 32 cells per parallel, not some subdivision of 8, otherwise you're running a lower operational voltage is my understanding. Are you trying to say you can just subdivide down to any mix of number series physical packs? Then why would you ever limit yourself to whole full 24S 100V or 20S 84V packs, which has limited EUC designs for the past 8 years due to space constraints, sometimes weird bridging of small packs wired to the main pack. And my higher load point was inferring that there is higher amp load per cell vs if you had another True 32S 134V parallel pack in-line, so that the load is spread across like 32S2P / 64 cells, vs the Master 32S1P / 32 cells, ie more True 32S Parallel. I was NOT saying that there was more load per cell on this 4 subdivided configuration vs a true whole 32S1P pack same number 32 cells.
@redfoxdude

@@houseofjob Ah, I see the misunderstanding. I agree that 32S1P would yield very high strain on the cells. However, the Master is not 32S1P - it is *_32S4P._* Each individual pack is _8S4P._ (For clarity: 8 cells in series gives you the 8*4.2V=33.6V pack voltage. 4 packs in series gives you the 8S*4 packs=32 series in total for the 134.4V system voltage.) There are a total of 128 cells in the Master, so each pack has 128/32=4 parallels inside: 32S4P. (EDIT: For some extra clarity: we can calculate that there must be 128 cells. The listed capacity is 2400Wh. The 50E cell has approximately 18.5Wh (3.7V*5Ah). 2400Wh/18.5Wh = 130, where 128 is the closest common multiple of 32, 32*4. Thus, the Master is 32S4P.) So it's a 4P like in the RS for example, in terms of the distribution of load across the cells. Each of the two RS packs have 2P, and two of those in parallel gives you 4P in total. As for why you would limit yourself to full packs, my main guesses would be cost and build complexity. It's been helpful in that way for Begode for reuse of the same pack in multiple EUC models. Otherwise, I'm not really sure. The Sherman splits each 100.8V pack into two 50.4V packs on either side.

@@redfoxdude I see. This is a better explanation yes, thanks. I forgot about the 128 total cell count, distracted by this foreign concept of summing the 4 physical packs to make the full 134V. I think the Shermona is a different beast tho no? it bridges the gap of BMS connect / split BMS, with a wire that only goes between the 2 adjacent packs, ie. no mix and match possible, no connecting of this communication wire to the XT60 or XT90 termination at the board, no using each pack independently. We had an engineer rider friend who was has since passed, who tried to explain something similar to this, splitting of Series count to sum as a bigger operational voltage, but I'm still admittedly struggling to wrap my head around that.

@@houseofjob Yeah, the Sherman's series packs aren't fully independent like the Master's - they have BMS connections between the series packs, like a split BMS as you described. I'm sorry to hear about your friend passing. I'm an engineer (electrical) too. Totally happy to chat about this kind of stuff, engineering is both my profession and my hobby =) As far as splitting the series count (ignoring parallels, let's consider any parallels as if you just have a single cell with higher capacity), when you follow the path of electrical current, say from battery (-) to (+), each time you pass a lithium cell in that path, you get a voltage boost (+4.2V if at full charge). The electricity flowing through the cells along the path doesn't care where you place the battery housings, if it's still along the same series path, you still get the same boost. So putting another pack in series, you add more cells into that series path, adding even more voltage. I don't have resources right off hand, as I am going off of my knowledge from stuff like nodal analysis. I don't wanna link that stuff though, way too into the weeds, ha!

Would it be possible to "jump" one of the four XT90 battery connectors to simulate a battery pack failing while still being connected to the wheel and keeping the circuit closed? If true then if one battery pack fails while in use it should still work... hopefully!!

High voltages in parallel is extremely dangerous requiring multiple bms to balance packs. Imbalances due to injury or defects can lead to runaway fires. Tesla has packs in both series and parallel but have extensive r&d. Begode probably chose lower voltage packs and in series which makes them much safer from fires. Damaged packs in series simply stop working. Damaged packs in parallel while working in redundancy can be a time bomb. Pick your poison.

I think Begode have changed this now to pairs, in series and parallel.. Not withstanding that, I can only presume each battery pack has its own BMS balancing each pack to 33.6V when it is charged. The packs then connected in series. An open connection on any pack leading to a cutoff, that would include a connector coming loose. Either way, on checking the voltages of the battery packs a discrepancy of any significance between any one of them could indicate a problem with the pack.

I think the peak power is the same regardless of parallel or series battery connections. The redundancy is good if any of the battery pack is malfunction, but usually that would not happen during a ride, so I think the pros of having a lower Amp system through the wires might help reduce the likelihood of fire. But if the fire is induced within a single battery cell which will have a run away effect, then we are talking about having a better BMS, which KS might have an edge. However it seems lower Amp system is better than having a better BMS (as per the latest KS fire incident showed). I am not sure which one is more effective in fire avoidance but my bet goes to having a lower Amp system.

The 33v packs can still explode. I'd recommend the S22 for safety. I would buy the Master myself because I don't trust either wheel. Every rider that wants to be sure needs to learn how to inspect the packs. On the S22 you can see warning signs on the smartBMS readout in the app. That still doesn't excuse one from opening up the wheel every once in a while and check for burnt cables and corrosion and water intrusion. I'm talking about a deep inspection, cell level with removed battery heatshrink if necessary. For S22 riders, their main concern should be the leap in voltage (for the brand) and the "over built" wheel design that may or may not introduce new failure modes. None of these wheels have been tested long term.
