I use 3 12V batteries wired in series for 36V, and use diodes to wire them in parallel for the 12V. The diodes stopping the batteries from shorting. I know diodes have a considerable voltage drop, and for the EV application I would use ideal diodes. By using the diodes, all batteries should drain equally, avoiding the battery pack unbalancing.
Ensure that the lithium batteries you intend to connect in parallel have the same voltage and SOC. Mixing batteries with different specifications can lead to imbalanced charging and discharging, which is unsafe. Batteries that are at different SOC should be charged or discharged to within 0.25 volts to prevent damage due to excessive current.
The diodes stopping the batteries from shorting. I know diodes have a considerable voltage drop, and for the EV application I would use ideal diodes. By using the diodes, all batteries should drain equally, avoiding the battery pack unbalancing. In the EV, the 12V batteries would be separate modules with their own monitoring. Is this a crazy idea?
That is, in applications in which the batteries are charged and discharged independently. However, OP's diodes are a solution in search of a problem: OP's batteries are not charged and discharged independently: no diodes are required. You can use blocking diodes to prevent the batteries from trying to charge each other when in the load circuit.
Create Series Pairs: Connect two batteries in series by soldering the positive terminal of the first battery to the negative terminal of the second battery. Do the same for the other two batteries. Combine Series Pairs in Parallel: Solder the positive terminals of both series pairs together using a wire.
The diodes stop the batteries from shorting to each other, but they also deliver 36 V to your '12 V' output. If your low voltage drain is very, very small, say less than 1% of the drain on the whole pack, then you could maybe supply it from one battery, and rely on the charger to rebalance the cells when you recharge.
