Fit and installation
Before ordering, compare the tip shape and mounting dimensions with the tips in your installed WP158 pen. The installed pen version determines fit; the welder model alone may not identify every accessory revision.
Switch off and disconnect the welder and allow the tips to cool before replacement. Seat the replacement tips securely and check alignment before testing a weld on suitable scrap material.
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.

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!
