48v 20AH Lifepo4 Battery for 1000W Electric Motorcycles Tricycles Ebike Electric Bike Electric Vehicle Telecom
Basic Information:
Item 48v 20ah lifepo4 battery pack
Size:150*170*300mm
Battery pack weight : About 8kg
Charge current : 3A
Continuous discharge current: 20A can be customize
Charging upper limit voltage: 58.4V
Discahrge cutoff volrtage : 40V
BMS (Battery Management System):
With built-in BMS for over-current, over-discharge, over-charge, short-circuit, adverse-polarity connection, balancing functions
These advanced 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.
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 |
