V2.0 kits are now for sale to the general public!

That’s it, we’ve finished shipping all of the V2.0 pre-order kits from our amazingly successful Kickstarter campaign. Now we are opening up sales to everyone else.

You can see the V2.0 kits here. This is our high power kit, rated for 20A per cell, meaning you could use this kit for high power applications or cases where you don’t have many parallel cells to share the load.

We are really excited about the applications the V2.0 kit has already been used in and the projects that you will be using it for in the future!

We currently have only a limited supply of V2.0 kits in our US warehouse, but we are working on getting more stock produced and shipped to us ASAP. So if you’ve been waiting for a V2.0 kit, make sure you grab them soon to ensure that you get one while supplies last!

V1.5 backorder is almost over!

First of all, thank you to everyone who has ordered V1.5 battery building kits during the backorder and has been waiting patiently for weeks now to receive your kits!

We’ve had a series of unexpected delays from random customs inspections to multiple trucking delays, but our shipment of V1.5 battery building kits has finally arrived in Florida after leaving our factory in India many weeks ago.

Tomorrow I am personally driving 4 hours to go pick them up and take them to our shipping warehouse, where our team will be working around the clock to get them out to you guys as quickly as possible!

Thank you once again for all of the patience and support you guys have shown us. We couldn’t do this without you guys!

Today is the day, V2.0 kits are finally available for pre-order!

Starting today, our new and improved V2.0 battery building kit is available for pre-order on Kickstarter at a discounted price! We’ve been working around the clock to make this the best battery building kit in the world, and we are sure that you will agree!

The new V2.0 kits are rated for 20A continuous and 25A-30A peak, depending on the length of the burst. This increase in power is due to the copper-based conductors we’ve designed for the new and improved kits. We can’t even begin to explain how much time and energy went into choosing the exact design and makeup of such small components, but after pouring over prototypes for months, we’ve finally solidified a breakthrough design that we couldn’t be more proud of!

We’ve tested these kits thoroughly on the bench, on electric skateboards and electric bicycles, and even soon in a solar race car thanks to Appalachian State University’s Solar Race Team using the V2.0 to power their next generation solar race car!

The V2.0 kits are available for pre-order now, with low-scale production already underway and larger-scale production expected to ramp up in the next two weeks. Delivery of pre-orders should begin in May, coinciding with when the V2.0 kits will be available for regular purchase in our shop. But why wait until then when you could order your V2 kit today and save a few bucks at the same time! And speaking of saving a few bucks, we’ll let you in on a little secret too: you can also pre-order the existing V1.5 kits on our Kickstarter page for almost 20% off the current sale price! If you don’t mind waiting a few weeks for delivery, you can get those for a steal of a deal as well!

Don’t forget to head on over to our forum if you have any questions about the new V2.0 kits. And thank you for all of the support, encouragement and most of all, patience, that you’ve all shown during the R&D process of the new V2.0 kits. It took a bit longer than we thought to finalize the design and prepare them for production, but we believe they are well worth the wait, and we know you’ll agree!

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.

Vruzend kits are getting an update! New colors!

We’ve been hard at work on some new upgrades to the Vruzend kits. We’re committed to taking a proven and effective product and finding ways to make it even better.

The first incremental update we are ready to roll out is the new color coded version of the kit.

The original kit contained all white caps, which meant that you had to mark the positive and negative ends of your cells. With the new color coded caps, making your battery connections is easier than ever. The red caps are for the positive ends of the cells and the blue caps are for the negative ends of the cells. Easy, right?

We’re also including an extra 4 caps in each kit, due to popular demand. The kits now come with 104 caps and nuts. The rest of the kit contents remains the same, including the specifications. We’re still hard at work on even more upgrades to the kit and we’ll be reporting back when the next version of the kit is ready, which will be the higher powered V2 kit meant for you speed demons out there!

You can see more pictures and specifications of the kits on the product page, and place your pre-order now. We expect to be shipping the new kits within approximately two weeks.

We survived Irma!

Thanks for your patience and well wishes everyone! We survived Hurricane Irma and were actually much more fortunate than a lot of people that suffered more damage than us. I rode the storm out at home and though we received a direct hit from the eye of the hurricane, we were fairly far inland and received only minor flooding in our neighborhood.

We have already begun sending out orders that were delayed due to the hurricane. It’s going to take us a few days to catch up completely, and we appreciate your continued patience while we ramp back up our shipping operation.

Lastly, we have an exciting announcement to make soon. Keep checking back on our blog here, on our Facebook page or on the YouTube channel for the announcement!

Shipping delay due to Hurricane Irma

Hello everyone,

Our warehouse and shipping center is located in southwest Florida, and received a direct hit by the eye of Hurricane Irma. We are all safe and uninjured and we are lucky to have experienced only minor damage. However, we have been without electricity or internet since the storm passed on September 10th (this post is being written by cell phone held over our head for reception – seriously).

We are unfortunately not going to be able to ship any orders for a few more days until power is restored and US Postal Service trucks can make it through the minor flooding in our area. We appreciate your patience during these trying times.

Please check back on our blog here for more updates and we hope to begin shipping again ASAP, hopefully in the next 2-3 days.

Thank you!

…And we’re back in action!

Hey everybody, we’re restocked with Vruzend battery kits and ready to start shipping again on Monday.

We really appreciate everyone’s patience. We have been slowly but surely increasing our production rate over the past month. The backorder period was shorter this time and we’re working on getting to the point where we won’t have to run out of stock again. I’m not sure if we’re quite there yet, but we’re close. And that’s all the more reason to grab your Vruzend kits now while we’re still in stock!

Even though shipping starts Monday for the backordered kits, it will take us a couple days to get through the queue of backorders. That means that any new orders that come in during the next few days will experience an additional few days of shipping delay. But don’t worry, we’re in stock so you’ll definitely be getting your kits soon!

Battery chargers for everyone!

We’ve been working on this for a while, and I’m happy to say that we’re finally stocking some really nice battery chargers to go with our Vruzend battery building kits.

We didn’t want to go with just any chargers though. These chargers are a great combination of features. They’re sleek, high quality units with built-in cooling fans and a 3A charge rate. Basically, they have the performance of the expensive chargers with the price of the cheap chargers.

The one thing they don’t offer that we had hoped for was adjustable output voltage, but that extra feature just increases the price so much that we didn’t feel comfortable asking that much for a charger. So we’ve got the best affordable chargers we can offer, with all the basic features you need… you plug them in and they charge!

If you absolutely need an adjustable voltage charger, there are other companies out there that offer them. We are partial to the Cycle Satiator from, but not everyone needs a $300 charger.

If you just need a simple, high quality charger that can charge your battery, or you’re looking for a spare charger to keep in the office, then this is the charger for you! We offer them in 36V, 48V and 52V options, all with a 3A charge rate. Check out the new battery charger line here.

The chargers come with a 5.5 x 2.1 mm barrel connector, and you can find the matching female connector here to add to your battery. Of course, you can also swap in whatever connector you need to fit your battery, if you are partial to another connector.

We’ll be ready to start shipping these in the next few days. Any orders that come in before August 11th will be pre-orders, as indicated on the product page.

Keep letting us know what other parts you’d like to see offered on and we’ll do our best to supply them!
