The case for this package is a 5″ plastic fencepost tubes sold by big-box hardware stores. The 60P1S BatteryBloc for 18650 cells fits nicely inside the fencepost tube. The top and bottom caps that fit the fence post tube are included. The top cap includes a voltage gauge so you can easily keep track of each parallel groups voltage. You can be sure they are balanced and detect problems.
The active balancer is not included and can be purchased here should you chose active balancing.
Also not included are the 5″ fencepost tubes. Figure about eleven inches for each parallel group. You can sit these on a shelf either upright or flat. You can hang them from the wall as well using Super Strut.
The Bloc holds 60 18650 cells. At 9 watt hours a cell, that is 540 watt hours. Put 15 in series for a 60 volt 8.1 KW Power Wall. Double the cells with a “DoubleDangler” for a 16.1 K Power Wall. Attach any number of Blocs in series and the balancers will move the power from the high voltage Blocs to the low voltage Blocs, 24/7 balancing the battery at the top, the middle and the bottom-
Cut the strut into 4″ lengths and bolt to the back top of the fencepost tube. Attach a length of SuperStrut to the wall studs, and hang the Blocs from it. Bolt the Blocs together in series.
