Q: Can you jump start a car with this? I feel like no. Id like to know why if so as in what damage could be done?

There will be no damage jumping a car from this battery. Only part that is at risk is the dead lead acid battery, that likely needs replacing regardless. However, you should not use one of these 12v LFP's to replace your lead acid. Alternators do not make stable power to charge lithium batteries.

Q: The 2 50ah batteries are mounted in series in the pride mobility scooter to power a 24 volt motor. Charging is via a 3 pin xlr connector. What charger

To charge 24V 50Ah battery system, the DC charging voltage should be between 28.4V~29.2V, and charging current less than 50A.

Q: Could the 300ah 12v be used to start a 3 cylinder 23hp diesel engine?

Since our battery is not a car battery, we do not suggest using it as a start-up battery. Our battery will be more suitable for house batteries. You could also kindly offer more details of your application, and I could see whether we could offer some suggestions to you.

Q: No low temperature cut off? I see replies both yes and no. Which is it?

Hi there, thank you for your inquiry. Unfortunately, the 12V190Ah battery does not have a low-temperature cut-off function. However, we have upgraded 12V100Ah and 12V200Ah with an auto-heating function that may fit your purpose. The auto-heating battery can be charged at ambient temperatures of -4°F/-20°C. I hope this helps.
