New Segway NCG2004-N battery vs original Segway 20967-00001 battery

The original 20967-00001 Segway lithium battery packs used LiFePO4 cells to make the 73.6V / 5.2Ah battery that was sold for the last 15+ years. The benefits of LiFePO4 are that it is intrinsically safe, has double the cycle life or Li-Ion, and is more tolerant to over-discharge to name a few of the major differences. There are plenty of videos available out on the internet which show that the LiFePO4 is a much safer battery if it is over-charged or punctured. The cycle life is going to be the key difference. LiFePO4 cells have an average rated cycle count of ~2000 in comparison to Li-Ion having an average rated cycle count of ~1000. This means that the new NCG2004-N Li-Ion batteries are expected to have approximately 50% of the overall life compared to the older LiFePO4 battery packs under normal use. You may be asking why in the world would anyone wish to go with the new Li-Ion batteries after reading what we just wrote?? The reason is that you can certainly get additional range off the Li-Ion battery packs compared to the LiFePO4. The "actual range" of the battery has been tested by a Segway dealer that we are acquainted with and we have provided their test results below.

 

Test environment: 85F temp, 165lb rider, riding around a perfectly flat track at a school until the machine does an emergency shutdown. Batteries were on the machine and plugged in for 24hr prior to testing. The rider held a steady 11-12mph during the test. 

20967-00001 LiFePO4 tested on Segway i2 @ 22.6mi

NCG2004-N Li-Ion tested on Segway i2 @ 28.4mi 

 

The results clearly show that the Li-Ion will absolutely provide a longer run time per charge but at the expense of safety, a shorter cycle life, and at a much higher annual operating cost. 

20967-00001 LiFePO4 @ $900 per battery  =  $900 / 8yr @ $112.50/yr

NCG2004-N Li-Ion @ $1100 per battery = $1100 / 4yr @ $275/yr

MTO 20967-00001 Battery Rebuild @ $650 / 8yr @ $81.25/yr
