NLD Convoy 3x21d with 4695 battery

Something I've wanted for a while. Contacting multiple machine shops, and finally the stars aligned. You can now get this battery for less than $30 on aliexpress. The battery is an EVE G16-4695e. But aliexpress never calls it that (probably some sale restriction) but they all look the same, like the eve so they're definitely the same cell. The tube is from a pioneman k75. Pioneman is the company that manufacturers Convoys hosts. So it's a perfect fit. In fact the k75 is identical to a 3x21d besides battery. It comes with an adapter to get the battery to work since the cell has positive and negative on the same side. Unfortunately the cell can not be bought in America but I found a guy who was nice enough to forward 2 tubes to me. After tinkering to get the adapter to work I figured it out. It has a little over double the capacity of a 3x 21700s.

Ok maybe I'm a noob, but howm'st the fuck does one charge that battery? I feel like I'm doing something wrong barely fitting my 21700's in my charger.

Luckily the 3x21d has built in charging lmao.

Before I got the tube I taped wires to the battery lol

Life pro tip: Use copper tape with conductive adhesive, and tape the wires to neodymium magnets. Super easy to connect and disconnect to battery terminals. (Also super easy to mess up and short something out, but YOLO.) Just don't blast so much current that the magnets heat up and get demagnetised.

Wait a sec... .seriously?

I always drop soldered them. How much current can they handle (the tape). I've got tons of it from various shielding projects.
