The one jason linked had 30mA balance current. The one I linked is twice that.

The balance current is quite poor and disappointing..
If the current is a lot higher, 0.5Ah> or more.. the boards will be much more usable

Farends: 500mA/0.5A and not Ah im guessing? Because Ah is capacity not current.

ALl or most of the cheaper boards are for Ebikes and such where you have low capacity in total. You get what you pay for and also the current you need to balance with depends on the packs you built.

500mA is what I mean indeed.
