I know this is a controversial topic but I think we all have something to say here and have made different experiences. So please share!
Gobelpower has built-in an active balancer into their battery which is great. It is turned on and active all the time though. From many tests we have done here on the channel, this causes an imbalance in the battery pack. It shifts energy between cells and when you fully charge again, the balancer does not have enough time to restore the initial top balancing. This especially happen during longer periods of no full charge (eg. winter or bad weather). Most likely, one of the cells will be peaking and causing the BSM to disconnect even before your reach you charge voltage.
So, here is the test:.
1. Fully charge and top balance the battery (we go with 58.2V and ~30mV deviation)
2. Fully discharge until one cell hits 2.5V
3. Recharge the battery again from solar over 2-3 days.
4. Compare the deviation to the initial top balancing achieved under 1.
And we are doing the exact same test twice, first one with the active balancer connected all the time, second cycle without any active balancer connected at all.
What will happen? Will we see a higher deviation with the balancer active all the time or does it not matter and it actually helps balancing the battery at the top and deviation is getting smaller?
Keen to read your thoughts about this experiment. I know, it's only one cycle but it still should give us an indication and direction where the journey will go.
Fantastic breakdown on how these balancers work from @StuartPittaway
