DeWalt 36v test?

[james1986]

Hi Guys,

Has anyone tested the capability of the dewalt 36v lithium packs as a whole? What I mean is, what kind of ampage can the wires of the BMS and cell connectors take? Has anyone tested this; if not I can do the test myself, I would just like some figures to verify. Thanks!

P.S. I don't mean what ampage can the A123 cells inside take! Just the connecting wires.

As I dont actually have any of the cells, I placed a 33ohm resistor in its place, and then attached the clips to the outside of the wiring on the plastic bit that would hold the cells.

When run at 10A the voltage was about 8v (high I know, but I'm not sure what difference this would have made), and the wires turned red hot and melthed the plastic.

I'm assuming that under no circumstances will I be able to charge my 'off the shelf' dewalt pack at 10A.

More to the point, what should I offer to the dewalt pack for charging, 36v 3.7v? I'm a little confused as to what the BMS does? Does it split the voltage to each cell, or the Ampage?

Thanks!

According to some previous posts, and the significant help of mn_aerorider1, the charging circuit provides a CC through a 15A fuse, which would suggest that it can take up to 15A of current whilst in this stage of the charging cycle.

Can anyone tell me if this is possible using regenerative braking as the charge source?

Thanks
