BATTERY CABLE CONNECTIONS

Up to 3 batteries are supported in parallel when connected to a single inverter, 4 batteries in parallel when connected to 2 inverters, or up to 5 batteries in parallel when connected to 3 inverters.

The maximum recommended number of paralleled 18kPV inverters is 6. If this approach is used, we recommend a ratio of 3 batteries per pack controlled by each 18kPV inverter. Separating packs is only recommended if each pack's average SOC is monitored over time and does not diverge by more than 10%. Common busbars are superior to separating battery packs but it may be difficult

Runs small
Size: 11 Wide Big Kid, Color: Black/White, Size: 11 Wide Big Kid, Color: Black/White
Runs extremely small, but does look like a nice shoe. I ordered 11W for my grandson. The image shows a different brand size 10 red shoe. As you can see the red one is bigger and wider than the new one ordered.

Good. Just good.
Overage at best. Not a bad sneaker for running and courts. The bottoms wore out faster than I thought but they are comfortable.

Sturdy, supportive, wish they were a bit more breathable
Bought these for my seven year old after he tore through a cheaper pair of tennis shoes in a month. These have held up very well, still looking decent after several months of heavy use, just a few minor scuffs. The fit is great and they are very comfortable for him. My only complaint is that they are not as breathable as I would expect and my son’s feet get hot and sweaty very easily inside. Overall, they’ve been very durable and I would buy again.
