The VRUZEND V2.0 is our high power battery building kit. The caps are identical in size and shape to our V1.5 kit, but the SS components are upgraded to copper coated with pure nickel for the highest level of conductivity and the best level of corrosion resistance.
Each V2.0 kit comes with enough components to build a battery with up to thirty (30) 18650 cells.
To build a battery with more than 30 cells, simply combine multiple kits together to reach any battery size you need.
Each basic kit includes:
- 60 cell terminal blocks with nickel coated copper alloy spring contacts (enough for 30 18650 cells)
- 60 screw terminals and nuts
- 70 pure copper bus bars coated in pure nickel for corrosion resistance and high conductivity
- 4 main wire clamps (for charge/discharge wires)
- 4 cable tie straps for securing the pack
The VRUZEND 2.0 kit includes all the parts necessary to join your cells together and create all of the electrical connections. However, you’ll still need a charger to charge the battery and a BMS if you you’d like to use one (recommended for safety). You’ll also need 18650 cells.
Please keep in mind that this is the upgraded V1.5 kit, and the interlocking dovetails may not be compatible with previous versions of the kit sold before mid-February, 2018.
Features:
No soldering or spot welding required… at all! You can finally build a battery with nothing more than a socket driver or wrench and your bare hands!
End cap standoffs – four posts on the end of each cap keep the conductive metal components off of your workbench and help reduce the chance of short circuits. Safety first!
Customizable and adjustable – build a battery of any size, and increase the battery voltage or capacity as your needs change. By simply moving or adding cell blocks and series or parallel connections, you can increase the voltage or amp-hour capacity of your battery easily!
Serviceable – if a cell ever dies, you can open up the pack and replace it!
High power – The V2.0 kit is rated for 20A per cell, allowing you to power even your highest power devices!
For assembly you’ll need a 5.5 mm socket wrench or nut driver. We know that’s a bit of an odd size, and even if you have a metric set of drivers, it usually jumps from 5 mm to 6 mm. So we’ve made it easy by supplying a 5.5 mm nut driver for cheap (in price, not quality!!), which you can by looking at my other items in eBay
We recommend that for best results, you limit the current draw of the battery pack you build with Vruzend V2.o battery caps to approximately 20 A continuous per cell. Current bursts of up to 25 A are acceptable, but for periods not exceeding 10-15 seconds. Higher current results in more waste heat being generated which can rob your pack of performance. That means that if you build a battery with 3 cells in parallel, you should try not to exceed about 60 A continuously with that pack, though bursts of higher current are ok. Also keep in mind that if your pack is contained without air flow around the cells, you’ll want to use somewhat lower current per cell as well, as the kits are rated at 20A per cell with sufficient air flow. We believe that 20A per cell will be enough for nearly any project though, and few 18650 cells can even withstand higher current than that anyways!
The Vruzend V2.0 kit works just like the V1.5 kit that has been tried and tested, but uses pure copper bus bars and copper alloy spring contacts to allow much higher power levels, as high as 20 A
