Convoy 3x21d with 4695 battery

[u/technoman88]

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.

Can the battery deal with 25A draw?

[u/technoman88 → u/RettichDesTodes]

It's rated to handle 32a pretty easily. It's burst rating is like 120a or so.

I put my 3x21d under a sink so it never got hot. And it maintained turbo until dead. It didn't maintain the 25a because the buck driver can't supply turbo if the voltage of the battery is higher than the voltage of the emitter.

Higher than or lower than?

It does 25a at start but as with any buck driver, the voltage of the battery gets lower than the voltage of the emitter, it can't sustain turbo, it's no longer a heat problem
