1. What are Renogy battery’s greatest advantages?
Firstly, our batteries use the most up to date pouch cell technology. Currently, there are a few battery brands on the market using pre-used battery cores, these have a negative impact on the battery’s life span and present safety risks. In addition, Renogy batteries feature, self-heating functions, an auto-balancing system and an advanced and efficient BMS system. Moreover, Renogy batteries have passed the free drop test，Electro Magnetic Compatibility testing, forced overcharge/discharge test，and crash test.
2. What exactly are pouch cells？
Soft pouch cells use a lightweight aluminum-polymer film to house the battery core, however most Li-ion batteries on the market today still use outdated hard metal battery casings. Comparing metal casings and pouch cells of the same capacity, pouch cells are substantially more light weight and have good cycle performance. When a pouch cell is damaged the gas and heat can escape through a sealing port, preventing further violent reactions. However, hard metal battery casings made from aluminum and steel are much more likely to explode when damaged.
3. My current RV is using a 12V system, if I upgrade to a 48V system what obvious life improvements will I see?
The most perceptive advantage of upgrading from 12V to 48V is that you will be able to use high-power electrical appliances in your RV. If you need to use high-power electrical appliances such as an air conditioner, refrigerator, or oven then a 48V battery will meet your energy needs and greatly enhance your off-grid living experience. Also, thinner cables can be used to connect the battery to the rest of this system, this will reduce transmission loss, save on space and improve the safety of your solar setup.
4. How long can this battery be used for?
This battery can complete 4500 full charge-discharge cycles and battery efficiency will drop to 80% of factory performance after this, however it can still be used with ease. If you live completely off-grid and charge and discharge the battery once a day it will last for more 10 years.
5. How many batteries can be connected together at once?
Up to 8 batteries can be connected in parallel, the auto-balancing function allows you to connect in parallel more safely.
5. I’ve never seen a switch button a battery before, what function does it have?
We have added one touch activation function to this battery. When the battery and BMS system aren’t needed it, they can be turned off with one touch, reducing wear and tear, making storage safer and extending battery life.
