I opt for a 24 volt leisure battery bank so that I could use a 24 volt inverter and for 12 volts… use a 24v to 12v converter. Plenty of these around as they are common in marine and truck applications. Using a 24 volt battery bank is more efficient and DC chargers 24v to 24v to charge the battery bank are available, again from the marine ...

Simply, connect both of the batteries in parallel where the overall battery capacity would be 400Ah and the same voltage level i.e. 12V. Keep in mind that battery discharge quickly in parallel as compared to series batteries connection.
When connecting multiple batteries together to create a larger battery bank, it is important to configure the bank so all batteries are charged and discharged as equally as possible. This makes the connection method and interconnection between batteries a critical factor to ensure batteries receive equal charge and are

I have a Li-ion battery charging circuit based on the MCP73113. This is designed to be a single-cell battery charger. The battery itself (3.7V, 650mAh) comes with its own PCB with Schottky diode and current regulators as protection. EDIT: Not a Schottky diode. Current limiter and a Protection IC. By design, they work together just fine.

A common house battery bank on pleasure boats consists of four or more, 6 volt "golf cart" batteries connected in series/parallel to make a 12 volt battery bank. There is no need for diodes or other isolation between batteries. Some people express concern that a shorted cell in one battery will cause overheating of the wireing, but I have had a ...
On the other hand, batteries connected in parallel increase the overall amp hour capacity of the battery bank, while maintaining the same voltage. For example, two 12V batteries connected in parallel will produce a 12V battery bank with double the amp hour capacity of a single 12V battery. Voltage and Current Basics

Both Bank 1 and Bank 2 are charged from a VE IP22 charger with "Lithium" settings (14.4 V absorption/13.5 V float). I then have a separate 7A VE charger set to 14.7/13.6V charging only Bank 1 to provide the 14.7/13.6V charge voltages for the Odyssey battery. The Schottky diodes prevent backflow to the LiFePO4 battery bank.
Most chemistry allows parallel configurations with little side effect. Figure illustrates four cells connected in parallel. The voltage of the illustrated pack remains at 1.2V, but the current handling and runtime are increased fourfold. you can study more about the batteries connected in parallel & series here.
Putting diodes in series will add the diode drops together. Reverse leakage (and capacitance) should reduce in this configuration. In parallel, the drop will stay the same (reverse leakage and capacitance will add), but the current capability may not be much higher, due to the possibility of thermal runaway (since as a diode gets hotter it''s Vf drops, then it draws more …
Circuit drawn I believe is correct, as I''ve seen this arrangement with a reverse biased smd diode inside several work tool battery packs. In these, the diode goes over the output terminals, full pack voltage. The smd diode in reverse is not big enough to sustain full pack current either.

In ideal circuit theory, the parallel connection of two voltage sources results in an inconsistent equation, e.g., a 3V and 2V source connected in parallel, by KVL, gives the equation: 3 = 2. In the real world, batteries are not ideal voltage sources; batteries can supply a limited current and the voltage across the battery does, in fact ...
The challenge with battery combiners is uneven battery banks, specifically when one battery bank is discharged heavily and another battery bank is full. When two battery banks are in parallel (joined together), they will instinctively want to even themselves out and the higher voltage battery will want to lift the lower battery bank''s voltage.
To imagine this lets say each long row of batteries in the room have an output of 240 volts and 500 amp hours and there are three rows connected in parallel so the total output of the battery bank is 240 volts and 1,500 amp hours (500 Ah x 3 rows).
