Progress report on the V2 high current kits

Hey everyone,

I just wanted to give you all an update on the status of the higher current kits we are producing. We had hoped to have them ready by the end of the year, but some of the production steps have proven to take longer to prepare than we expected. The spring contacts and threaded terminals, which will use copper alloys, are going to be silver brazed and nickel coated, but these additional steps have added to the complexity for production on our end, meaning it’s taking us just a bit longer to finalize production.

We are getting closer though, and the prototypes have been very promising so far. Early testing shows we are already into the double digits for amps per cell, but we won’t have a final amp rating on the new caps for a few more weeks. We’re continuing our testing and pushing the caps higher and higher to see how much current they can handle.

There will also be some new improvements in the physical cap design as well. A similar but redesigned shape is proving to allow much higher tolerances meaning cleaner and crisper edges, smoother interlocking, less struggling to align the dovetails and stronger caps that can stand up to a huge amount of abuse. We’re also upgrading the polymer as well to makes the caps even stronger than ever!

We appreciate you all hanging in there – I know a lot of you are excited about the higher power kits we’ll be debuting (based on the daily emails we’re getting from enthusiastic battery builders). I’ll be back here soon with some pictures and a more concrete release date for the new kits.

  1. Fantastic. I was contemplating buying a spot welder. I think I will wait. Your already into double digits so it looks like it is going well!!

  2. Awesome work! Glad to see this kit coming along so well. I’ve been looking forward to a high current solution for a 72V pack I’m building. Any way we could possibly begin pre-orders for these high current kits?

    1. We have not yet opened pre-orders in the US, but pre-orders outside the US can be taken at

      1. That’s good news! Hopefully the U.S. pre-orders are coming soon! The Vruzend kits are the final ingredients in my new e-trike build!

  3. Last update was mid-March on the V2 High Current kits. Any updates?

    1. Yes! April 17th! That’s the day we’ll debut the V2.0 kits and launch orders 🙂
