12V Lithium BATTERy TECHNOLOGY
RJ 12V Lithium battery is made with LiFePO4 batteries cells. The rated voltage of lifepo4 cell is 3.2v, 4 battery cells in series for a 12.8v rated battery pack. Compared with traditional lead acid batteries, or Gel battery, or Gel battery, 12V lithium iron phosphate battery is the most efficient of all kinds. RJ offers a whole line of 12 volt lithium batteries with various capacity from 10ah up to 800ah for applications in RV’s, electric marine Boats, EV's and off-grid solar household applications and so on. high performance of the 12 v lithium battery make sure you power everything you want to in the system.
much Longer life span, means more recreation time with the RJ 12v lithium battery. This 12V lithium battery deep cycle lithium battery is the best solution for replacement of a group 31 AGM, GEL or lead-acid Battery. Lighter in Weight, smaller in size makes it the best substitute to replace the lead-acid and become one of the most popular lithium batteries ever used in RV fans, Campers, Boats.
The 12V lithium battery is more compact and more powerful gel or AGM or lead acid battery. Charging at Max 1C rate, discharging at max 2C rate, which makes it a excellent combination of dimension and capacity energy for wide applicationss such as , RV, marine, solar energy systems etc.
RJ 12v lithium batteries offer much more energy for high consumption than lead-acid or AGM or gel batteries. Also more high efficiency of discharge and charge round trip, it is up to 98.5%, and it can be discharged to 100% depth of discharge. Which means we do not have to leave a extra energy in the battery, on the contrary, every energy we charge the and store in the battery can be drawn out for use. If you buy a 12v lithium battery rated at 200ah, then with 100%DOD, you can discharge it to a totally energy of 12.8v * 200ah, which is 2560wh.
unlike other 12v lithium batteries in the market, which you will find out that their lithium battery are not made equally.therefore the consistency of it is very poor. RJ 12v lithium battery adopt high quality and high consistency battery cells to avoid this and make sure high consitency is possible. Our 12v lithiumbattey is made with a built-in Battery Management System (BMS), The BMS manage and protects the 12v ltihum battery with high-accuracy State of Charge (SOC) calculations. Over charge, over discharge , short circuit or over currrent all can be avoided by cut off the load when single cells of the 12v lithum battery reach a high voltage of 3.65v and a low voltage of 2.5v.

Features
- Multiuse Battery: our 12v lithium battery not only for solar energy storage system, but also widely use for electric vehicle, Marine boat and RV caravan camper, telecom base station, medical equipment, Energy power backup supply, military emergency backup equipment and any 12V, 24V, 36V and 48V application.
- Use in Series : Our 12 v lithium battery can use as drop in replacement for any 12v 24v 36v 48v battery application. It can be hooked up to 4 Batteries in Series. While this is available, we still recommend you to do a directly 24v , 36v, 48v battery instead of hooking up 12v in series. Because we need to enhance the bms inside and customize it for you to hook 12v battery in series, which will adds some unnecessary cost, but above all, it is more robust and envery saving for you to use a directly 24v , 36 v 48v battery , more safe and more stable and reliable. To avoid you get confused while hooking up 12v battery in series. And will be more easy for you to charge it if you take a direct battery 24v 36v or 48v.
- Parallel Connections: our 12v lithium battery can be put in use in parallel up to 32 batteries, this is a great flexibility if you need to expand your existing system in the future. You simply add a new 12 v lithium battery to your system anytime in the future and you are done. With 12v 200ah, the max energy you can reach will be up to 6,400ah.
