Wait a second. Those wires say “VCC” “TXD” “RXD” and “GND”. Which makes me think they are the UART connectors for the BMS.
BUT
If the UART Terminal for the BMS is on the FRONT of the CUSTOM PCB, then that leads me to believe that the BMS is actually populated onto the back of the PCB.
@ducktaperules did yall have a custom PCB built with balance tab connectors and the full BMS populated onto the back?!
I would love to see some IR imaging and pack impedance and inductance measurements. Great data if there was to be a V2 pack and I’m just really interested in that kind of stuff.
LOL…actually, that’s exactly what can’t be posted. It just hands any competitor data they can use…nvm.
@Battery_Mooch if you would need to choose a cell for a 12s1p pack which should be able to output 35A (not continues but for like 10-20second peaks) and the overall capacity would be not main priority, which cell would you choose? P42A, 30T or any other?
At 35A…
If slightly cooler temps are the priority then the 30T.
If slightly longer running time is the priority then the P42A.
No other round cells to recommend at that high a level. There are huge LFP cells around though with very high current ratings but I have not tested them.
I haven’t done cycle life testing of the 30T in order to compare them that way.
35A as battery max setting for the esc.
That doesn’t mean there will be a constant draw of 35A. I would assume the average current draw would be somewhere between 15-20A max.
In fact I try to get a mini cruiser short range single drive board build and was hoping to get along with a 1p config and reasonable voltage sag while riding.
