## Questions & Answers

**Q: Is the lowest percentage discharge for maximum life-span 50%, as with other lead-acid batteries, i.e. usable kilowatts is half the rated value?.**
A: Hello Leon, 

Thank you for getting in touch with us regarding our 12V 300Ah AGM battery bank. 

You are correct. As with other lead-acid batteries, it is best to avoid discharging this unit more than 30-50% of its rated charge; in order to increase the longevity and the number of cycles that can be achieved. 

We hope this helps. If you have any other questions about the performance of this panel, please contact us directly over the amazon messaging portal.

Kind regards,

**Q: what type of charger and charge controler is needed for this bateries?**
A: Thank you for your interest in our battery banks. Any charger that is designed to charge sealed lead acid batteries rated at 12V will be suitable to charge these batteries. We sell a range of both solar controllers and mains battery chargers that would be compatible with this battery bank. Please ensure that if you are using a solar controller, that your solar panels are within the limitations of the unit, as exceeding these limits can damage the controller. 

If you have any questions, please feel free to get in touch with us directly. 

Kind regards,

**Q: How should I buy the cables to connect to the inveter?**
A: Hi,

If you are referring to our battery terminal size being M10 and not M8 then you will need to find some 10mm ring terminals by searching online. You should be able to find them at different cables sizes suited to what your inverter needs and crimp them onto the cable. 

Any further questions please let us know. 

Kind regards,

**Q: bateries require powerful energy supply, e.g.:  what? there is missing info. could you kindly provide more info, please?**
A: Thank you for your interest in our battery banks. I believe that the section of the description says ‘The long service life and improved depth of discharge of this battery bank make it ideal for applications requiring constant, reliable and powerful energy supply’. This is to say that it can act as a powerful energy supply for campervans, off grid systems, etc.

It will require some source of power to recharge between uses which can be mains power, a solar system or similar battery charging systems.

If you have any further questions, please feel free to get in touch with us directly.

Kind regards,
