View moreNo, if the packs of different capacities have the same C rating, the current draw from each pack will be in proportion with its capacity of the paralleled pack. e.g. - Draw 60A from a 1000mAh pack in parallel with a 5000mAh pack and the 1000mAh pack will deliver ~10 amps and the 5000mAh pack will deliver ~50 amps.

View moreI thought that Ohm''s law, V = IR, meant that batteries with the same voltage, introduced into the same circuit (with the same resistance), should push the same current.

View moreGenerally speaking, there is no big harm to connect multiple charge sources to the same DC bus. Especially as you have described. There can be issues though. If the DC bus voltage is artificially high because of one charger, another charger may think the batteries are very full, and then change it''s charge state accordingly.

View moreHowever, if you connect batteries with different voltages in parallel, they will try to equalize their voltages and this can damage them. If you connect multiple batteries in parallel, the overall voltage of the system will remain the same, but the capacity will increase. This is because each battery adds its own amp-hour (Ah) rating to the total.
In general, it is best to connect batteries in series because this increases the voltage while keeping the current the same. However, there are some advantages to connecting batteries in parallel. For example, if you want to increase the current without changing the voltage, then connecting batteries in parallel is the way to go.
Connecting batteries in series is only practical if the batteries are very similar. So if you know each of your pair of serial batteries (for instance the 2x 12V 55Ah) have the same capacity, you can do that. You might want to measure the available capacity of the batteries. You also must balance the loading process!
If you have two 12 volt batteries and want to connect them in parallel, there are a few things you need to know. First, connecting batteries in parallel will not increase the voltage. The voltage will remain at 12 volts. However, connecting batteries in parallel will increase the amperage or amp hours.
Putting different capacity batteries is series will lead to disaster because the lower capacity battery will charge up faster and become grossly overcharged, causing it to vent and release gasses that cannot be replaced - and perhaps even explode! Batteries lose performance and may go out of balance as they age.
Therefore for best performance you should only combine batteries which have the same age and usage, preferably new batteries bought at the same time. Connecting random batteries together will probably give poor results, as the older weaker ones will not provide the expected capacity.
