If you have a project that requires some serious battery power, and can’t find a battery pack that matches your requirements, making your own is possible, but usually expensive as the commonly used spot welding method requires expensive tools.
Vruzend has created a modular lithium-ion battery building kit that greatly ease the making of DIY battery pack using 18650 battery cells using caps, nuts and bolts.
There are two versions of the kit: V1.5 kit which supports up to 3.5A continuous and 7A peak per cell, and for higher power levels, the new V2.0 kit can handle up to 20A continuous (25A peak) per cell thanks to nickel plated copper-based conductors. It makes it suitable for EV racing, high power battery banks, and other power-hungry projects. The short video below explains how the kit works.

Vruzend battery build kit is now offered on Kickstarter, and the projects has been fairly popular so far with $45,000 raised with 3 days to go. Rewards start at $25 for a single V1.5 kit good for up to 52 battery cells, and $28 for a single V2.0 kit for up to 30 cells. Other rewards combine multiple kits with up to 10 V2.0 kits for 300 cells ($260). Shipping adds $14 to $62 depending on reward, and delivery is planned for May/June 2018.
If you are interested in the subject, but are not sure how to get started, the designer’s “DIY Lithium Batteries: How to Build Your Own Battery Packs” book should help.
