I don't replace the Li-ions anymore since I can't ship them.  I convert the box to NiMH using your existing charger.

So I pulled the battery out of my Tinybox. It has a pull off connector so it should be easy to swap out.

The photo of the connector in this link looks a little different. Is it just the photo or is it a different connector they are selling? When it comes down to it, I know I can solder the old connector to the new battery (the one without the connector), but I'd like to avoid that since my soldering skills are a little lacking (ie it will work, but it might not be pretty).

Here is a photo of my connector (sorry about the quality).

Bonus photos of the inside of the Tinybox (1.0).

If I remember correctly Jon didn't use the connector that comes with the battery so I think you would need to get a bare wire battery and solder it into your existing connector.

Jon announced a new forum on his website one of them is about battery life in the "box" series see this thread:
On November 14, he states:

The box series amplifiers were in production from 2009-2014. Those that shipped with internal rechargeable lithium-ion batteries are all near or at battery end-of-life.

Because shipping regulations have gotten more strict since these devices were produced, it is no longer legal to ship the lithium-ion batteries used. Therefore, I do not offer lithium-ion battery replacement. All box series amplifiers can be converted to run on NiMH battery packs instead, as follows:

littlebox/midbox/bigbox: A 6x 2/3 AA NiMH battery pack is a drop-in replacement for most littleboxes that previously had a lithium-ion pack. There is no circuit reconfiguration required. Some littleboxes with input or output transformers in the standard case size might not have sufficient internal room for the NiMH pack, which is slightly larger. The NiMH pack with mating connector is $20.

tinybox & tinyhead: any tinybox version can be reconfigured to use a 5x AAA NiMH pack. The cost of conversion (including new battery) is $50; a new battery pack is $20. The charger originally shipped with the tinybox must continue to be used with the NiMH pack.

PIPsqueak: all PIPsqueaks use a 4x 1/3 NiMH AA battery pack. A replacement pack including connector is $20. I have found that 1/3 NiMH AA batteries have variable initial charge capacity, which can cause premature pack death when the weak cell dies. Thus, I test each battery individually before I assemble the packs.

Yeah my TB battery is pretty much at that point (and built toward the end of the run)...  Though it apparently isn't supposed to work this way (Jon indicated it wouldn't) I'd discovered if I plug it into a power outlet it supplies power (indefinitely of course), so an extension cord now travels with the rest of my gear.  That is working until I will have enough downtime to send it back for replacement...  If I use it 007 the battery is still more than adequate for the SP's.  It seems to be down to about 2 hours of phantom power though and still dropping...
