Honda fit Hybrid and Honda Spyke have almost same hybrid system installed and the only disadvantage this car has is that its DC-DC converter is also placed at the rear battery pack which heats up quickly and if by any chance the battery cooling fan is faulty or choked the car will cause many problems like loss of power or completely stop altogether.

The blue arrow shows the lithium-ion battery pack. The green arrow shows the service plug.
Types of batteries
The Toyota Aqua uses the nickel metal hydride battery pack placed under the rear seat and the PCU (which integrates the inverter, DC-DC converter and the booster converter) over the transaxle / transmission in the engine compartment.
The Honda Fit Hybrid uses the lithium-ion battery pack and the PCU (inverter and the DC-DC converter) side by side under the trunk. The battery pack and the PCU are separated from each other by foamed styrol.
The yellow arrow points to the IPU cooling fan, and the white arrow to the outlet duct. Air taken from the inlet duct flows through the lithium-ion battery pack, the PCU, and the cooling fan before it goes out from the outlet duct.
