1.Is this really maintenance free?

Yes, Li-Rack is absolutely maintenance free, you don’t have to add any sort of battery water or clean the terminals.

2. What does One Cycle mean?

A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load.

3. Will this battery be safe to install at home?

Yes Li-Rack is absolutely safe to install at home and is non-flammable as well as non-explosive. Some model are available with wall mounting features to save space.

4. Do I have to use this battery system daily?

No, You can leave the Li-Rack unused to a period up to 6 months safely, the battery charge or condition will not deteriorate.

5. Does it have any protection?

Yes, Li-Rack comes with inbuilt protections like over voltage, under voltage, over current, under currents, fault detection. The system automatically disconnects in case of any faults so that all your appliances, home, shops, industry is absolutely safe.

6. What is remote monitoring of the battery?

Li-rack is the first Internet Ready battery which comes with a remote monitoring feature which helps you know the health of the battery, state of charge and many other parameters. Also gives a warning on faults!

7. How can I charge the battery?

Li-Rack can be charged by solar power, wind power, grid, and/or any dc source of the appropriate ratings.

8. Can I get custom sizes as per my requirements?

Yes, custom size are available on special requests, you can write to us on sales@vmechatronics.com

9. How much time does it take to charge these batteries to full capacity?

Li-Rack can be fully charged in 2-3 hours.

10. How much time can we discharge?

A full capacity of Li-Rack can be discharged in one hour.

11. Is it programmable?

Yes, Li-Rack is programmable to suit your requirements.

12. Does this emit any fumes or pollutants?

No, Li-rack does not emit any fumes or pollutants, it is completely eco-friendly.

13. Do I have to add battery water to this every month?

No, You will never have to add battery water to Li-rack.

14. Are these batteries recyclable?

Yes, Li-rack is recyclable and has a second life too.

15. Can they sustain hot and humid climate of India?

Yes, Li-rack can sustain Indian weather conditions. It can operate in temperatures from -25°C to +50°C.

16. How much space will these batteries require?

Li-Rack is very compact and does not require a lot of space, some models are even wall mounting.

17. Where have these batteries been installed till date?

Li-rack has been successfully in Germany, United Kingdom, India. Till date 4.6MWh+ capacities have been installed and running successfully.

18. After how many years should I replace these batteries?

The life expectancy of Li-rack is 20 years* (8000 cycles @ 80% DoD), so install Li-Rack and forget replacement headache for the next 20 years.

19. Any Tests carried on these batteries?

Yes, In cooperation with the University of Applied Sciences in Ansbach we have tested our LiFeYPO4 cells under extreme conditions. The lithium cell is discharged to 70% DoD approximately 33 times per day with 1C charge and discharge current. We have exceeded 9000 cycles! The results confirm a very high load capacity and reliability, and verify the superior quality of the cells used for our LiRack batteries.
