If one battery is 10A then two means [the battery bank can take] 20A of charging. Just be aware that the Orion 12 12 9A is a converter and so does not have three stage charging. If you are using it to boost battery charge that is ok, but longer period of runninwill mean battery overcharge which is bad for them.
When assembling lithium-ion cells into functional battery packs, it is common to connect multiple cells in parallel. Here we present experimental and modeling results demonstrating that, when lithium ion cells are connected in parallel and cycled at high rate, matching of internal resistance is important in ensuring long cycle life of the battery pack.
It is important to note that the actual heat transfer in a battery pack may be more complex due to the presence of multiple cells, non-uniform temperature distributions, and the influence of the battery pack geometry on the air flow patterns.
Abstract: In renewable energy power generation system, the battery storage unit is necessary for suppressing voltage fluctuations and ensuring stable operation.

As lifetime still remains an issue for battery packs, it is a necessity to monitor the battery pack''s state-of-health (SOH) on-board.
The performance of lithium-ion battery packs are often extrapolated from single cell performance however uneven currents in parallel strings due to cell-to-cell variations, thermal gradients and/or cell interconnects can reduce the overall performance of a large scale lithium-ion battery pack.

With two batteries in parallel to charge, It will be cut in half not doubled. If you are talking about the Charge current applied from solar with two batteries in parallel, It will be cut in half not doubled. If your MPPT produces 20A into the 2 batteries, it will be felt as 10A into each battery (Assuming same SOC).
But bulk model ignores inconsistency between the batteries, and when the current magnification is large, such as in the extreme fast charge scenario, this neglect cannot reflect the current distribution inside the battery pack.
Uneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells. Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections.
