I have 3 dewalt 12v battery packs, identical. I'm familiar with parallel charging. Any reason I shouldn't give this a go? Of course small increments of time, watch the temp, but other than that, it seems like a go to me.
im sorry i meant to say im gonna wire them up in series then parallel charge the bird battery.

Yes, it worked wonders.
