Yes, you can mix different capacity lithium batteries, whether a normal 12V 100Ah battery or a Lithium server rack battery. You can combine different capacity batteries in parallel. You cannot combine different capacity batteries in series. There are a few points you need to consider when wiring in parallel. Let’s explore these three points.
To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+). For example, you can connect four Renogy 12V 200Ah Core Series LiFePO4 Batteries in parallel. In this system, the system voltage and current are calculated as follows:
Fortunately [Adam Bender] is on hand with an extremely comprehensive two-part guide to designing and building lithium-ion battery packs from cylindrical 18650 cells. In one sense we think the two-parter is in the wrong order.
To wire multiple batteries in series, connect the negative terminal (-) of one battery to the positive terminal (+) of another, and do the same to the rest. Take Renogy 12V 200Ah Core Series LiFePO4 Battery as an example. You can connect up to 4 such batteries in series. In this system, the system voltage and current are calculated as follows:
There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we’ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.
Lithium ion batteries in parallelis to increase the amp hours of a battery (i.e. how long the battery will run on a single charge). For example if you connect two of our 12 V, 10 Ah batteries in parallel you will create one battery that has 12 Volts and 20 Amp-hours.

Battery configurations (series and parallel) and their protections
Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V. Each cell has one another cell connected in parallel to get the double capacity of 6800mAh.
