12v battery pack without welding

Spot welders are expensive. The good ones cost more than the price of most lithium batteries! Cheap ones are dangerous and prone to breaking when you need them most. Plus, spot welded packs can't be opened up to replace a single cell if it ever goes bad. VRUZEND kits can! With VRUZEND's innovative DIY battery kits, you simply work with your hands!

In somewhat of a departure from their normal fare of heavy metal mods, [Make It Extreme] is working on a battery pack for an e-bike that has some interesting design features. The guts of the pack are pretty much what you'd expect – recovered 18650 lithium-ion cells.

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!

They can be snapped together like Lego™ bricks to create any size battery. Then simply bolt the cells together using the supplied connectors and you've got yourself a custom lithium battery pack for a fraction of the price of buying an off-the-shelf lithium battery pack.

You'll also need 18650 cells. 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.

Easy Ebike Battery Building Kit - Join 18650 Cells with No Welding! - Vruzend V2.1 Review The VRUZEND V2.1 is a high power battery building kit. The caps are similar to the 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.
