1. Are RJ 12V lithium battery safe to use ?
Yes, our 12 volt lithium battery is made of lithium iron phosphate battery cells, which is the safest lithium material of all kinds. Our battery has already passed IEC international standards test, which includes test as below:
T1. Altitude simulation test- our 12v lithium batteries are stored at a pressure of 11.6Kpa for at least 6hours.
T2. Termal test- our batteries are stored at a test temperature up to 75 degree, followed by a termperature -40 degrees.
T3. Vibration test- batteries are under vibration with frequency from 7Hz to 200Hz and then back to 7Hz.
T4. Shoct test, our batteries are subjected to a shock with acceleration peak 150gn
T5. External short circuit test
T6. Impact/Cursh test
T7. Over charge test
T8.Forced Discharge test
Test result of above required no leakage, no venting, no fire, no explosion.
Our RJ 12v lithium battery has all passed through. With which We are confident to say our battery is safe to use, particular for RV Camper, Caravan, Marine boat and ship etc.
2.How long is RJ 12 Volt lithium battery expect to last?
Generally, our 12v lithium battery has a lifespan more than 15years. Here is the calculation for reference. If charge rate less 1C, discharge rate continuously less than 2C, discharge fully 100%DOD, our 12v lithium battery is expected to have 6000cycles. And after 6000cyles, there is capacity retention at least 70% of original. You can do the math, if the 12v ltihium battery is being used for 1 cylce per day, then you will be using at least 365cylces per year, and with 6000cyles, you can expect it with a lifespan more than 15years.
3. I would like to use your 12V lithium battery for my electric boat, but will it explode?
No. it won’t explode under any circumstances. Our test data shows that The self-ignition temperature of lithium iron phosphate batteries is 800 C, that is to say, under any realistic extreme conditions, lithium iron phosphate batteries are basically impossible to self-ignite, nor will explode. This outstanding performance makes our 12 v lithium battery , which made from lifepo4 chemistry, a best solutions to power marine appication such as electric boat, yachts, RV trailers.
4.Can I leave a battery charger connected to RJ 12V lithium battery in my RV?
Yes. Each of our RJ 12v lithium battery has made with a matching BMS which will take care of charging control for the battery. In general, Lithium-ion batteries are charged with constant current, then constant voltage. A constant value of charging current decreases gradually with the increase of charging voltage, and finally decreases to almost zero. Therefore, it is no problem to continue to put it on the charger after charging. This is make it convenient for customers to automatically charge the battery possible.
5. Do I always fully charge it everytime when I charge 12v lithium battery?
Generally speaking, unlike lead acid battery, our 12V lithium batteries are not very demanding for charging because they have no memory effect. You can charge it to 100% fully, and If the time is not enough, charging up to 80% is also no problem at all.
And if you plan to not be using the 12v lithium battery for a long time, for the lithium battery pack to be idle, the recommended charging level is 40%.
6. Can 12v lithium battery be 100% fully discharge without damage to battery?
Yes, that is no problem at all. For our 12v ltihium battery, which is made of LiFePO4 Battery cell, has a limited discharge voltage of 2.5v and limited chargge voltage of 3.65v for each single cell. Within this range of voltage, which is 10v and 14.6v, our 12v lithium battery can be fully discharge without any problem. Many people farmiliar with lead acid battery, which claims to be deep cylce battery, but actually, they can only discharge to 60% to 70%, this is in fact not the real deep cycle. On the contrary, our 12v lithium battery can be truly deep cycle while discharging. This is another feature and advantage of our 12v lithium battery over lead acid battery or AGM Gel battery in the market.
