Help me understand how to choose a battery for AC200PL

Good day. Please help me understand the confusion. We bought a station AC200PL. And now we are looking for an additional battery for the station, we are interested in a battery with increased capacity (B300 series). One of the online stores responded that the station supports B300/B300K.
Is it so? The problem is that in our country (Ukraine), there are many B300K, but not enough B300, and B300 much more expensive. And help me figure out the connection, if this is it B300K/B300 - do you need the same cables to connect? And which ones?
Thank you very much for your help

@N1k3 It is recommended to purchase the B300K. You can connect it to the AC200L/PL in expansion mode using the standard cable that comes with the B300K.

Non-K is obsolete and discontinued. However, it is/was basically the same, but slightly better: has no fan (unlike K, but K’s fan should be quiet), has 12% more capacity, has USB-C & 12V outputs, but height is bigger.
If you need absolutely largest capacity, then try to get non-K, but only it it will cost no more than +15% to the cost of K.
In all other cases, K is the way to go, I especially like its lower profile. And when using with AC, you won’t be needing USB-C & 12V on the battery anyway.

Cables are same and included with battery. Personally, I use AC200PL+B300 and will add B300K on arrival.

The new B300K is better in other ways It has more rated cycles 4000 cycles vs 3500 for the B300 and has a higher energy density while retaining the safer LiFePO4 battery chemistry. So:

  • B300: Heavier, more features, worse price/performance ration, more capacity, no longer in production.
  • B300K: Lighter, less features, better price/performance ratio, slightly less capacity, more cycles, in production.

I bought a second B300 from a dealer that still sells them. Because I already have a B300 with my AC300 and I want to keep things uniform. If I would buy my unit today I would go for two B300K batteries because the price/performance ratio is better and both batteries are of high quality.

Cable for synchronization with the station, is it definitely included with the 300K? I asked a question on one of the well-known Ukrainian sites - and received an answer that there is no cable included.

@N1k3 Please refer to the screenshot of the B300K official manual. The P090A cable included with the packaging is compatible with AC200PL/AC200L;

however, I can’t be sure if the local distributor in Ukraine will sell the cables separately.
