FAQ
1. What can I do if I use Solar Power to charge 12v lithium battery?
When you have a existing PV solar power system and plan to charge the 12v ltihum batery, all you need to do is to check whether the inverter in your system has a inbuilt charger, if not, then you need to add a battery charger into the system before you can charge the 12v ltihum battery. We can also recommend you a matching charger if needed, since we have excellent partner who doing charger manufacturer so good price and top quality can also be guaranteed.
2. I used lead aicd battery in the past, now with 12v lithium battery, What is the size of battery should I purchase?
As for the battery size, one thing is for sure, that with the same capacity and energy, 12v lithium battery is much more lighter and smaller in size than the old lead acid or agm or Gel battery. And as for the specific size you need for the 12v ltihum battery, it is up to how much power your system consume daily. Add the power of all the appliance in your RV or marine boat together then you will get a total power, then divided it by 12v, you will get a capacity you need for the 12v lithium battery. Unlike lead acid or AGM or gel battery, our battery can discharge to 100% dod without any damage to the battery itself, so if you consume 200ah per day, then you can choose 12v 200ah battery which will meet your needs. Of course, you can choose a 12v 300ah if you like to make sure sometimes you need more energy outdoors. That is up to your budget on that.
3. How long is the lifespan for the 12v lithium battery?
Our 12v lithium battery, with lifepo4 battery cells, is tested to have at least 6000cycles at 100% dod with 1c charge and 2c discharge condition. This outstanding performance make sure it can last at least for 15years under normal use. It is free of maintenance and no need to add water into it since it contains with no water at all. It is also environment-friendly since it contains zero poisonous materials.
4. Can I use 12v lithium battery to start the boat engine?
Generally speaking, 12v lithium battery is designed for energy storage and low speed electric cars, not for enegine cracking. But if you do need it to crack the engine, we can customize it for you. Price is the same. You can contact us for more details, our engineer team will help provide you a specification for the engine cracking 12v lithum battery.

Feature for 12v lithium battery
RJ 12V lithium Battery features our Bluetooth and mobile App monitor system. It is very convenient when you want to check out how the lithium battery operates, simply open the app in the smart phone and then it shows real time operation data about the 12v lithium battery including voltage, current, load, power , temperature, time remaining before charging etc. also, our 12v lithium battery features its high power output capability. Most other lithium battery drop in batteries only limited by a 100 Amp while discharging, our RJ 12V lithium battery models offer a discharge continuously at 2C, which means 400A for a 200ah 12volt battery. You can use less batteries to power the same load in applications.
