DIY500AMP.COM Design Notes
This product is officially distributed by DIY500AMP.COM – tested and approved for compatibility with our full range of AWithZ welders and copper/nickel busbar systems. Perfect for builders who value clean, consistent welds and long-lasting tools.
Fit and setup
These are welding pens for a compatible host, not a standalone mains-powered welder. Confirm the installed pen version, lead connectors, and matching replacement tips before ordering. If you need help checking a connector or tip, contact DIY500AMP support with the welder model and a clear photo.
Switch off and disconnect the host welder and let the tips cool before servicing them. Keep the tips clean and firmly seated, and test the setup on suitable scrap before working on cells.
Orders ship from Florida when inventory is available. Lithium-ion cells require proper handling, protected packs, correct chargers, and safe storage. Do not solder directly to battery terminals.
Payment and Security
Your payment information is processed securely. We do not store credit card details nor have access to your credit card information.

One of my cell orders was short one cell
One of my cell orders was short one cell. When I went to send a text to the customer contact (this is rare and awesome way to reach out), the reply on a national holiday came within 15 min. That level of customer service is incredible, like family. I really appreciate that!

Wow, these cells are great!
I purchased some of these tabless cells to try on my 1S 3" HD Toothpick drone build, and, albeit a bit heavy for 1S, it flies pretty well. Not a freestyle monster, but an endurance beast with decent send. These cells shrug off the demands of a BETAFPV Matrix HD AIO flight controller/12A ESC and some 1202.5 11000KV motors. I'm getting 15+ minutes of speedy flight time from a single cell trying not to go below 3.2V, and about 20+ minutes cruising. Love these cells and will definitely buy more when time comes, only from DIY500AMP, who are terrific!
