Re: PSU's and DC-DC convters or Is There An EE In The House!?

said by elios:

check the cell chemistry on the fast charge cars there not Lipo they are using Li-Fe/A123 which you CAN charge an insane rates

Many production hybrid cars have been switching over to lithium polymer since Hyundai did it back in 2008:

The Elantra LPI HEV will be the first car in the world to use lithium polymer rechargeable batteries ... significant advantages over lithium–ion batteries including higher energy density, lower manufacturing costs, being more robust to physical damage and they can also take more charge–discharge cycles ...

... with the Powerlab you can link up to 16 of them lol to run of the setting of 1 IF you REALLY need that much

Powerlab appears to be the end of innovation for RC folks.

Anyway, your original problem is solved by a multi-phase DC-DC boost converter: more phases = more current @ constant voltage.

got my stuff in and setup
PSU is putting out 25.5v so should be good to go
only tested up to 30amps on the charger so far but looks good
