The new version of Relativities arrived. I made new moulds to pot them for protection. With plugs, all the wiring can be done without risk of damaging the Relativities. A wiring test circuit was also provided, so all wiring can be tested to make sure it is connected correctly before connecting Relativivites. A brilliant setup. They are also now made in 8 cell units (balancing 8 cells), as well as the 4 cell units (balancing 4 cells).
I have 5 x 8 cell Relativities and 1 x 4 cell Relativities. They are connected across 44 cells, not overlapped. I am using the 14.8v chargers to break up and distribute the charge across the pack and then Relativities active balance all the time in a smaller area.
It is great to see a cell difference of only 0.08v each morning. Relativities and the 14.8v chargers are working well.
Except I have a couple of cells that have a higher self discharge than the rest of the pack and so I have the single cell (3.7v chargers) setup in that area of the pack. One of those 2 cells, only started about a week ago, became obvious when lower than the rest. I have 3 x 3.7v chargers connected to it and so it gets 12A help every morning.
With a new pack, or a pack well looked after, Relativities may work by themselves without the small chargers, but not this pack I have now.
Relativities has been connected for a few weeks now. All working good. They are over the back of the battery pack. There was not quite enough room above the batteries. The plug adds a little more height to the units. An example picture of the monitor screen shows just 0.08v difference between the highest and lowest cell. This is how it is every morning.
