4 x QNBBM Single cell vs 4s QNBBM Balancer

[nate_syd]

Does anyone know the differences - is it just packing & expandability?

Purchase 4 of these & chain them together:


Or a single one of these:

I use a QNBBM-8S and I like the one-piece unit. I also have a box of the singles like above but decided against using them because of the extra complexity. I have ordered in a HelTec Active Capacitance Balancer for a new battery pack I am setting up for the toolshed solar system. These are also Known Good and less costly.

This is their 3S/4S 5A model.
