Run Ansible Taks for several Groups in Parallel
We have many similar hosts that are grouped to specific types. Every group has several hosts in it, mostly 2 to 8 for scalability within the type. Now we need to run the same tasks/role on all these hosts. Serialised within each group but all groups at the same time. This should run much faster than all groups (about 10 groups currently) in a row.

Wiring Batteries:Series and Parellel
Please re-read post #3. You can do what you wish, but you are advised to not series connect batteries of different manufacturers, different capacities, different ''C'' ratings, or those having different use histories. All cells are not created equal. If you series pack ''A'' with different pack ''B'', ''A'' might be quite content with the current, but ''B'' might really object to that

6 FAQs about [Battery groups are not allowed to run in parallel]
Should batteries be wired in parallel?
In the realm of electrical setups, the concept of wiring batteries in parallel is a fundamental one. We’re essentially connecting two or more batteries side-by-side. This boosts the total energy storage (battery capacity) without altering the voltage. A Simple Analogy: Think of batteries as water tanks.
Should you add more batteries to a parallel system?
However, while the allure of adding more batteries to a parallel system is tempting, it’s essential to strike a balance between capacity and safety. Internal Resistance: Batteries, from deep cycle batteries to standard lithium-ion ones, even of the same type, can have varying internal resistances.
Can I Run 6 batteries in parallel?
You can run 6 batteries in parallel, no problem. However, worst case situation, without separate fuses on each battery, a failing BMS (dead short) in 1 battery means the wires in the battery to the BMS will have to handle the max current of all the other remaining batteries.
What happens if you charge a rechargeable battery in parallel?
for secondary (rechargeable) batteries – the stronger battery would charge the weaker one, draining itself and wasting energy. If you connect rechargeable batteries in parallel and one is discharged while the others are charged – the charged batteries will attempt to charge the discharged battery.
Can A LiFePO4 battery be connected in parallel?
Our Lifepo4 batteries can be connected in parallels and in series for larger capacity and voltage. Allow to be extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 800Ah) and higher voltage (24V, 36V, 48V). Looking at Chins or Ampere Time batteries from amazon (12v200ah models) and they both say 4s4p MAX. Why is this?
How do parallel batteries work?
The basic concept is that when connecting in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example: two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah).
