Grok says : The average efficiency of portable power stations typically ranges from 80% to 85%, depending on the model and battery type. Factors such as energy conversion losses, inverter efficiency, and battery chemistry (e.g., lithium-ion or LiFePO4) can affect this range.

The battery comes with the special cable to connect to the mega 3.
Mega 3 is big and has wheels and handles. B2 has two handles to carry.
B2 can be put on top. When connected, with their app, you can see the charge status of both.
It charges from 120 V at full speed (like 15 A) or half speed so it fills up in under 2 hours i think.
When charging from panels, if you plan to charge both, connect the panels through anderson plug to the B2. When it is full, the mega 3 will receive the electricity and charge. If you plug the panels to the mega 3, when full it will not to charge the b2.
I have contacted their tech support a couple of times with thechncial questions and they answer within a day with a complete answer.
When connecting panels, it likes a higher voltage (compared to other batteries that don't want more than 30v) so it's ok to put up to six 240W panels in series. Just make sure no panel is shaded. so no need to think i can use 1, 2 or 4 or 6 but not 3 or 5 panels. (as you would if you were connecting panels in parallel)
TL;DR: the tech seems good. Tech support is responsive. price is competitve.
The Mega 5 is the only one that takes the b5. The b2 also works on smaller mega 1 and 2 as well as titan 3.
If you need more you can use multiple b2 in series.
