I bought these last year thinking I would make a large self-managed BMS, but instead ended up just using battery medics.


These little balance boards are a great compact way of balancing 6S packs and multiple can be put into parallel to increase the balancing speed.

Price is $10AUD each or $100 for the lot.
Happy to ship anywhere for $7 local to Australia, $15 international.
I only have 14 and once they are gone that's it.
Cheers
