3000W Panasonic NMC 18650 Rechargeable 60V 24Ah Lithium Battery Pack
ULTRA! High Performance Lithium-Nickel/Manganese/Cobalt Batteries.
These advanced 'Next-Gen' batteries for 2018 are the most energy dense (190Wh/kg), lightest weight, and highest performing (65amp continuous, 100+amp peak) E-bike batteries on the market today at this very affordable low price. The super high current - 100+amps on demand translates to lightning fast acceleration/high torque when used with capable motor systems! It is amazing that batteries this compact can have such a phenomenal performance, long range, and extended lifetime. We also use a very high power BMS (battery management system) to maximize the capability of our cells. Battery packs are ISO9001 certified to maintain high quality standards.
You can also choose power connector for your battery including Male/Female Disconnects , Gray Anderson ,Smaller Red and Black Anderson, and XT90.
WE can make CUSTOM sizes with a variety of specs upon request. Custom sizes require 3-6 weeks to manufacture and deliver depending on requirements.
Comparing LiFePO4 to LiNMC
In spite of the various chemical variations, lithium-ion batteries can generally be separated into two groups: lithium iron phosphate (LFP, LiFePO4) and metal oxides (NMC, NCA, Cobalt, Manganese). Table 1outlines the differences between LFP and LiNMC chemistry classes on a cell level. The values in the table reflect average values as there is variation in each class.
Table 1: Lithium-ion subcategory comparison
| | LFP | LiNMC |
| Voltage | 3.3 V nominal (3.6 V/cell) | 3.7 V nominal (2.7-4.2 V/cell) |
| Energy Density | 300 Wh/L | 735 Wh/L |
| Specific Energy | 128 Wh/kg | 256 Wh/kg |
| Power | 90 - 120 W/kg | 512 W/kg |
| Cycle Life | 1,000 @ 100% DoD 2,000 @ 80% DoD | 750 @ 100% DoD 1,900 @ 80% DoD |
| Calendar Life | 6 years | 8 years |
| Max recommended temperature | 40°C | 55°C |
| Commercial Suppliers | A123, Valence, BAK, BYD, K2, Lishen, many Chinese vendors | Sanyo, Panasonic, Samsung, DowKokam, Sony, LG Chem, Moli |
Important Note Regarding LiNMC Battery Care
All lithium-ion cells are “deep cycle” meaning that they have the ability to be fully charged and discharged. The life of the battery will significantly increase if the depth of each discharge is limited to 80% of the rated capacity.
Comparing LiNMC to Lead Acid
Table 2 provides a brief comparison of lead acid to LiNMC on a pack level. It should be noted that both chemistries have a wide range of parameter values, so this table is only a simplified representation of a very complex comparison.
Table 2: Battery Technology Comparison
| | Flooded lead acid | VRLA lead acid | LiNMC |
| Energy Density (Wh/L) | 80 | 100 | 250 |
| Specific Energy (Wh/kg) | 30 | 40 | 256 |
| Regular Maintenance | Yes | No | No |
| Cycle life | 1,200 @ 50% DOD | 1,000 @ 50% DoD | 1,900 @ 80% DoD |
| Typical state of charge window | 50% | 50% | 80% |
| Temperature sensitivity | Degrades significantly above 25°C | Degrades significantly above 25°C | Degrades significantly above 45°C |
| Efficiency | 100% @20-hr rate
80% @4-hr rate
60% @1-hr rate | 100% @20-hr rate
80% @4-hr rate
60% @1-hr rate | 100% @20-hr rate
99% @4-hr rate
92% @1-hr rate |
| Voltage increments | 2V | 2V | 3.7V |
Figure 1 (from Battery University) compares the specific energy of lead, nickel- and lithium-based systems.
While NCA is the clear winner by storing more capacity than other systems, this only applies to specific energy. In terms of specific power and thermal stability, Li-manganese and Li-phosphate are superior. Li-titanate may have low capacity but this chemistry outlives most other secondary batteries in terms of life span. It has also the best cold temperature performance. As we move towards electric powertrains, safety and cycle life are becoming more important than capacity alone.
