Re: li-ion 18650 Adjustable size BATTERY HOLDER - Honeycomb Layout

The cell holders showed up and look excellent. You do need to pay attention to make sure that all of the dovetail joints are properly connected, and the shipping was quite expensive. Once the package left Poland, which took around a week, it was here within a day and a half (Houston, TX). They are ...

Re: 3rd ebike battery. This time, doing it right

If the white plastic housing material is polyethylene or polypropylene, most glues won't stick to it. They make a special glue that will stick, but it is not commonly available at the local hardware store. Many types of tape will stick well, however, so you may want to use tape along the edges to k...

Re: 3rd ebike battery. This time, doing it right

Are you testing the cells to make sure they r alll the same mah. Or atleast group the ones the are similar? If not I urge you do this or your pack will lose charge quickly. And make sure every cell is at least with in .1v of each other.

Re: New or Rebuilt Lithium-Ion Battery Service

Yes that is a very good price. Do you know the type of cells are being used? If it’s 18650s that’s an awesome price but I’m thinking because of the ah it’s a pouch pack? Is a charger included. Does that include a case? Just curious?

Re: 3rd ebike battery. This time, doing it right

Did anyone talk you out of soldering these cells together as the heat will defiantly damage them and take a couple hundred mah away?? It’s a great idea to spot weld. You can make one very cheap with a capacitor. Look it up on YouTube. Please.
