1.48V 20Ah Lifepo4 Battery with Built-in BMS board
2.58.4v 3A charger
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 |
