RJ 12v lithium battery
* only 1/3 the weight of lead acid battery with same energy
* Over 6000 100% discharge cycles while lead acid only has 300 cycles.
* can be discharged to 100% compared lead acid can only use 70% of the capacity.
* High discharge rate and quick charging capability;
* very low self discharge rate, no more than 6~8% per year;
* has a wider operation temperatures of -20 to 75 deg.C
* can put in parallel or series to reach higher capacity and voltage for different applications.
* Absolute Maintenance free;
* contain zero in any toxic heavy metals lead, cadmium, which makes LiFePO4 batteries the most environmentally friendly battery chemistry among all kinds of lithium battery.
