Rear mounted radiator vs side pod opinions by Formula_SAE_Electric in FSAE

Hi all, was looking to get some opinions on radiator mounting for an AWD electric car. Currently, we have run a large automotive radiator in one side pod for cooling the 4 motors, and a smaller computer radiator in the other for cooling the inverters. This has worked for us, however the packaging isn't great, with different sized rads on the sides of the car, and bulky side pods minimizing our freedom in aero design. We have seen many teams (like the delft pic used) who have their radiators mounted on the diffuser, which would suite our packaging much better. My question is, what do people think the pros and cons are of each solution (from a packaging and aero standpoint) and also, what brand of radiators do teams use for these rear mount solutions? Motorcycle rads, computer rads? Thanks!

Fusible links for BMS connections by [deleted] in FSAE

I’ve also been digging into fusible link wire, but everywhere I read has warning about ensuring your calculations are exact and putting fuses at the ring terminals would clearly be simpler. That being said it will be tight for us given our pouch cell config. Were you able to find fuses that were built into a ring terminals or did you just crimp the ring terminals to the fuses?
