Are LiFePO4 ready for 60v scooters?

I found these 30v 10ah batteries at Powerizer.

Is this a good price? Has anyone bought from them before? Can 6 on these be installed (2 series of 3 paralleled making 60v at 30AH) on the xm2000, z20, or zap scooter? What other venders are out there who sell something like this?

I think they'd work - but 6 would set you back around $2673.24 so it's not a very good price.

You could get 20 LiFePO4 40Ah cells (for a 60v 40 Ah pack) from electricmotorsport.com for $2000 (33% more power for 20% less money). That's 83 cents per Wh.

Foxx (see another post on this board) are offering cells at $0.95 per Watt Hour - so a 60V30Ah pack would cost $1710. Unfortunately PJD didn't have very good luck with their responsiveness - but maybe that will change?

Not all LiFePO4 batteries are created equal - I don't know the relative quality of any of these three solutions.

Great find. Has anyone tried them out and can I get some feed back?

Can I just wire 20 of them up in series with no problem (60v at 40AH)?

Electric Motorsport isn't selling BMS and for a charger I think they'd sell you a custom programmed Zivan. The battery they're selling is thundersky and there is a thundersky groun on yahoo!groups which has been there for years (and years and years) the the people there are very familiar with not just the thundersky batteries but other lithium batteries.

Re: Are LiFePO4 ready for 60v scooters?

I was wondering if you could take those 20 LiFePO4 cells and group them into five banks of 4 cells each, and use five 12v Vector chargers to charge each bank of 4 cells. Would a Vector smart charger work to charge 4 LiFEPO4 cells correctly? I understand that each cell is 3.2v or so charged. What voltage do they need to have applied to reach full power when charging? I'm assuming no BMS.

Would the 4 cells in each bank get out of balance with each other? I am thinking about going this way, and also using the new PakTrakr for Lithium to monitor each cell. I think the PakTrakr would at least tell me if the cells were out of balance; not sure what I'd do with that info though.

I recommend Kennedy Alternative Energy. They have a much better price on these cells, and a quality inspection and assembly process for LiFePO4 packs of any specification. You can save Thousands compared to batteryspace on a large pack like this.
