I am about to purchase an Autosleeper which comes with lithium 69ah battery. I have a differing manufacture 100ah battery (Both new), can I run them in parallel?
69 ? Depends on where youre going to have it I suppose .... but you would both definitely need to be parallel...

Yes, it is OK to wire two lithium leisure batteries in parallel without either battery becoming overloaded with charge or discharge. However, there are a few things you need to keep in mind to ensure that the batteries are properly balanced and protected:
Use the same size, brand, and age batteries. This will help to ensure that the batteries have the same voltage and capacity, which will help to prevent them from becoming unbalanced.
Use the correct size cables. The cables that you use to connect the batteries should be the same size as the cables that came with the batteries. This will help to prevent the batteries from overheating.
Use a battery management system (BMS). A BMS is a device that can help to protect the batteries from overcharging, over-discharging, and short circuits.
If you follow these guidelines, you can safely wire two lithium leisure batteries in parallel without either battery becoming overloaded.
Here are some additional tips for wiring lithium leisure batteries in parallel:
Charge the batteries individually before connecting them in parallel. This will help to ensure that the batteries have the same charge level, which will help to prevent them from becoming unbalanced.
Use a fuse or circuit breaker to protect the batteries from overcurrent. This is especially important if you are using the batteries to power high-current devices.
Monitor the batteries regularly to make sure that they are properly balanced. If you notice that one battery is becoming more discharged than the other, you may need to adjust the charging settings.
By following these tips, you can safely and effectively wire two lithium leisure batterie
s in parallel.
Probably best to check with both manufacturers. Some say their batteries can be connected in parallel but perhaps it interferes with cell balancing on others.
