The 12P Blocs are very popular. They also work well with the BabyBloc Balancers.
You get everything you need to make a 12P1S battery. That means you will be able to connect twelve cells in parallel at 3.6 volts. When you order more than one Bloc I assume you are going to assemble them into a larger battery and include everything you will need. If you are building more than one battery with your order the list will change slightly so let me know.
These Blocs are also great for charging up to 12 cells at once. Don’t bother with the bolts, just pop the cap on. The neodymium magnets hold the cells together for light use. You can use small magnets to temporarily attach your leads.
All BatteryBlocs accept both new cells and cells with spot welded nickel strip. Salvagers, just cut the nickel strip and install the cells. No burs to file!
Cells are for illustration purposes, not included.
