I initially enquired about their square 8085200 cells which are 10Ah.
She said they were 30A Max, and suggested a 38120 cyclindrical cell as an alternative:
I asked for 15C and qty 230...maggie wrote: And here is the detail information for 38120 cells:
Const.discharing rate: It could be according to customer requirements. We can meet 10C, even 15C, but different rate with differnt price.
Pluse discharging rate: It is also depended on customer's requirments. Our cells could be 20C.
Const.charger rate: 0.2-0.5C
Pluse Charge rate: 1C
Depth of discharge for highest number of cycles:70% DoD for 2000 cycles, 80% DoD for 1500 cycles, 50% for 3000 cycles
Discharng protection votlage: 2.0V
Charger protecting voltage: 3.65V.
Now I have asked for weight and internal resistance (oops):maggie wrote: Thank you so much for your reply.
Do you confirm that you need the battery with 15C discharging. for High rate discharing, the capacity for 38120 would be 8Ah.
And the price for 38120 8Ah with 15C discharging, the price would be USD16.5/RMB112 FOB SHENZHEN.
Here attached the picture for 38120 cells. It is cylindrical 38mm diameter X120mm length.
15C / 6 mOhm 3.2V I work out to be 67kW with 224 cells.maggie wrote: The weight would be 340g for per cell.
I made a mistake, the internal resistance would be 6 mohm.
These should suit a short range high voltage (600V) EV, 208 cells for 28km @ 150Wh/km, ~US$3400 FOB.
