Are the Heltec style balancers better than the QNBBM style balancers?

Hey Jeremy, thanks for the video.....I see you have 2 balancers, at what point do you decide to use a 2nd one or is it just how the config on that style bank you have?

On a different battery bank (200aH Yinlong) I was using a single 5 amp Heltec balancer. The cells would consistently be around 25mV within balance. I added a 2nd balancer to that bank and it kept it in balance within 5mV. When I first built this 160aH SCiB bank I used the QNBBM balancer because I already had it laying around and it was rated for 10 amps. Once I determined the QNBBM balancer was faulty, I just decided to go with the 2 Heltecs based on the scenario I had with the 200aH Yinlong bank.
