Package Preview:

This is for a piece of the brand new LiFePO4&ternary Segway Batteries, with the brand new shells, new BMS and new cells. We are the only two companies that could design and manufacture the BMS of Segway batteries, one is the original battery, the other is us. Thus we can offer very competitive price than any other companies. 

These batteries will work with all I2, X2, I2SE, X2SE, and other gen one Segways capable of using LiFePO4 batteries

If our battery doesn't work, we will send new product for replacement. 


Check more details of the battery in the below link:

15Charge protectionWhen the Battery modules are charged to full, MOSFET
disconnect the charger.
16BalancingThe intra-module balancing circuit is used to compensate slight capacity imbalance among the 23 cell blocks within a battery module. 
17State of Charge(SOC)
Individual cell block voltage and charge/discharge current will be used to monitor the state of charge (SOC) of the battery module. The estimated capacity used for the calculations will be adjusted to meet the capacity of the lowest capacity cell block when the battery system is fully cycled. The state of charge will be adjusted for normal self discharge of the battery system when the unit is not on charge. 
18I2C CommunicationI2C Communications will be used to communicate with the SEGWAY, and compatiable with blueteeth 4.0 and iOS&Android APP 
19Status LEDA Dual LED on module to indicate working status. One is green and the other one is red. Blinking of the green LED indicates that the module is working properly. Blinking of the red LED indicates that the module has failure and needs service.
