First,  Lithium battery Green Bank GB48300 15.36KWH 48V 300AH is unique of art compact size lithium battery , in addition, it has the capability to be connected in parallel for up to 12 battery banks, make it a unique up to 180KWH battery bank of 48V, 300Ah for commercial and residential settings., when it comes to safety , Lithium iron phosphate is one of the safest chemical combination that yet show a strong performance efficacy with the long life provided of 8000 cycles and its 10 years warranty in an affordable price point makes this battery bank is  customer’s choice to Lithium battery  into their existing solar system.

the GB48300 battery has its own state of art battery management system (BMS).  that ensures the best performance in majority of adverse working condition and one of the off-grid setups battery choices.

in addition, the cells are CATL, CATL is the full name of Contemporary Amperex Technology Co., Ld, is a leading lithium battery company all over the world located in Ningde, Fujian, China. CATL is the Number One Lithium battery manufacturer in China. CATL has very high quality factory with latest automatic technology. The company supplies more than 30 percent of the world’s batteries. CATL secured the mining rights for a lithium mining in Yichun in Jiangxi province for 123 million euros.

According to CATL,

Generally, The mine is expected to yield 2.66 million tonnes of lithium metal oxide makes this Lithium Iron phosphate chemical combination is here for years to come.

  • Lithium Battery Cell voltage
    • Minimum discharge voltage = 2.0-2.8 V[22][23][24]
    • Working voltage = 3.0 ~ 3.3 V
    • Maximum charge voltage = 3.60-3.65 V[25][26]
  • Volumetric energy density = 220 Wh/L (790 kJ/L)
  • Gravimeter energy density > 90 Wh/kg[27] (> 320 J/g). Up to 160 Wh/kg[1] (580 J/g).

Lithum battery chemistry offers a considerably longer cycle life than other lithium-ion chemistry. Under most conditions it supports more than 3,000 cycles, and under optimal conditions it supports more than 10,000 cycles. NMC batteries support about 1,000 to 2,300 cycles, depending on conditions.[5]

Mostly, the Lithium battey cells experience a slower rate of capacity loss (a.k.a. greater calendar-life) than lithium-ion battery chemistry such as cobalt  or manganese .
