Rechargeable battery pack

I have a WAOKS Model 3.65V 10A battery charger and a Powerizer 3.2V 100Ah (320Wh) LiFeMnPO4 Rechargeable battery pack. There does not seem to be a way to connect the battery to the charger. The plugs are not compatible. Do I just cut the end off of the output cord on the charger and hard wire it to the studs on the battery?

Before I do anything I think I would verify that the battery is compatible with that charger?
3.2V sounds low to me and not a good match for that charger. Very bad things could happen if you get it wrong. A really bad fire comes to mind.

like the answer you got on CNET, I’d worry a bit.
