Deep Cycle Lithium Battery 12 volt 100Ah LiFePO4 Battery For Solar
1. Is RJ 12 Volt lithium battery chemistry Lithium-Iron Phosphate or LiFePO4 or LFP ?
Yes, we are lithium battery manufacturer for over 16years, we, for years, have been focusing on Lithium-iron-phosphate, LiFePO4, LFP, which is the safest in performance and has the longest lifecycles of all the li-ion battery types in the market. Our RJ 12 Volt Lithium batteries has a lot of advantages over other battery chemistries. Safe and reliable, no thermal runaway no catastrophic meltdown, above all, its long cycle life, 6000cycles at 100% DOD, under high rate of 2C discharge and 1C recharge rates, and the round-trip of efficiency reach 99.2%, with this outstanding performance, our RJ 12 Volt Lithium battery is now a best solution when it comes to energy storage application.
2. Can you elaborate what BMS is, what specific functions does it provide?
Not just 12v lithium battery needs a BMS, actually, all lithium battery , from 12V up to 96V, all the needs a BMS for Protection.
Our RJ 12 volt lithium battery is made with a built-in BMS which provides functions as below:
● Over charge protection
● Over discharge Protection
● Short Circuit Protection
● Over current protection
● cell Balancing function :
● RS485/RS232/Bluetooth/Wireless communication function(Optional)
3. Is Battery Management System (BMS) a must in RJ 12 volt lithium battery?
Yes, if you take a look at the discharge diagram of LFP cell, you will see the working voltage of it is between 2.5V to 3.65V. within this range, the energy of a lifepo4 cells will be drawn out totally. And if discharge and charge exceed this range, it will cause damage to the lithium cells, which is not allowed. This is why we always need to make a lifepo4 12V lithium battery with a BMS inside the battery pack to protect it.
Another function that BMS will provide is the cell function. The great performance of 12 volt Lithium batery relys on the consistency of the lifepo4 cells inside it. The BMS will monitor each battery cell while charging, and provide auto cell balance at the end of charge cycle to ensure each cell will be the same voltage after charged. There are two options for Cells balance function, active and passive cell function. All RJ 12 volt lithium battery will adopt the passive cell function if not specially required, because under most of the situation, passive cell function is already enough.
4. Why 12V lithium battery safest of all li ion battery type?
our 12V lithium battery is made of Lithium Iron Phosphate, namely, LiFePO4 batteries, which are the safest chemistry of all kinds of Lithium batteries, why is that? We have several internaitonal test that proves this. UN38.3, 1.2M drop test, Destructive test, over heat test, over current test, short circuit test, when doing this, the lifepo4 cells are perfectly working without overheat, nor catch on fire, nor explosion, nor expand etc. material in LiFePO4 batteries is not hazardous, no pollusion to the environmental neither. Each lifepo4 lithium prismatic cell has a vault in the outer shell, when unexpected air generated internally, it will automatically open to release the extra pressure of air, this makes sure no explosion possible.

12V Lithium Battery is a high energy density and deep cycle battery built with prismatic lifepo4 battery cells as well as BMS. LiFepo4 is the most safe and longest life cyles chemistry, 6000cycles at 100% DOD, with the in built BMS which manage and protect the battery while working in its peak level. Our 12 v lithium battery serve as "drop in replacement", it is very convenient in use, nearly plug and play for many application such as RV, marine boat , golf car, solar energy system etc. you will find it the best solution ever for you to replace the heavy and large and old lead acid or gel or AGM battery.
