Question ThinkPad T batteries

Two months ago I bought my very first ThinkPad (T480) and at that time opted for the largest battery (model 61++) 72Wh available. This battery feels great and lasts pretty long with a full tank.

However I am now considering scenarios where I might forgo bringing the charger along all together, but likely need additional battery. After some initial difficulty with Lenovo site search, I managed to re-identify the compatible battery models (i.e. 61, 61+, 61++ which I already have)

Was wondering though, instead of purchasing direct from Lenovo and waiting a couple of weeks, are there some preferred brick/mortar shops that offer a wide selection of ThinkPad batteries? I've gone more than five years operating other laptop models with no external battery design.

Will it be more convenient to get a laptop power bank instead, considering the practicality and usage wise?

Price is much different.

Well I did have such a device before, when I was operating the light Acer Aspire 1820PTZ. It had a wide variety of connector pins and voltage/current settings, which was a necessary complexity back then when USB-C was not a thing. It didn't last long though. Must have been due to my ignorance of Lithium-ion chemistry at that time; it bloated pretty bad and ultimately had a very low charge capacity.

I'm sure there're newer models designed for contemporary laptops but I suspect it will cost more than a regular battery. Since I'm no longer operating a laptop with only a single sealed internal battery (ok, my Microsoft Surface Pro 4 is still serviceable but it's trash for heavy utility purposes), I'm no longer keen on the idea of using a battery to charge another battery when it can be swapped.

If their web site is up to date, I don't see models for ThinkPad T480.
