v2.1 DiY kit (for max 30 18650 batteries):To build a battery with more than 30 cells, simply combine several kits together to achieve any desired battery.Each basic set contains:60 cell terminals with nickel-coated copper alloy spring contacts (enough for 30 18650 cells)60 screw terminals and nuts80 pure copper bus bars coated in pure nickel for corrosion resistance and high conductivity4 main terminals (for charging / discharging wires)4 cable ties to secure the packageThe VRUZEND V2.1 is our powerful kit for batteries. The caps are similar to our V1.5 set, but the SS components have been upgraded to copper coated with pure nickel for the highest conductivity level and the best level of corrosion resistance.The V2.1 kit replaced our V2.0 kit by adding cylinder bolts to compress the package connections. This ensures consistent connections, even in environments with a lot of vibrations.Each V2.1 set comes with enough components to build a battery with up to thirty (30) 18650 cells.The VRUZEND 2.1 set contains all the parts needed to join your cells and make all electrical connections. However, you still need a charger to charge the battery and a BMS if you want to use one (recommended for safety). You also need 18650 cells.Characteristics:No soldering or spot welding required ... not at all! You can finally build a battery with nothing more than a socket wrench or key and your bare hands!Spacers on the end cap - four posts at the end of each cap hold the conductive metal components of your workbench and help reduce the chance of a short circuit. Safety first!Adjustable and adjustable - build a battery of any size and increase the battery voltage or capacity if your needs change. By simply moving or adding cell blocks and series or parallel connections, you can easily increase the voltage or ampere capacity of your battery!Maintenan
