Re: what's quality for Ieehoo LiFePO4 Batteries

New one to me. What is your application? bicycle or something bigger? In general the best lifepo4 has a C rate better than 2. But for some things a low c rate is fine if the pack is large enough in ah. At least they don't show the round cylidrical cells that now are getting a bad reputation on ebay.

Be the pack leader.

Re: what's quality for Ieehoo LiFePO4 Batteries

I would be interested in hearing more about this supplier as well. I have e-mailed them, but as of to date, I have not heard from them. I did spend a fair amount of time reviewing their web pages. One thing I think I figured out is that it seems the LiFePO4 batteries are rated at, let's say 100 Ah, that is the ONE HOUR rating. My 75 Ah SLA batteries are rated 75 Ah for 20 hr rating, and the 1 hour rating is only about 50 Ah. This may be common knowledge to most, but it was helpful to me for understanding how the LiFePO4 energy density translates to increased range and average maintainable speed.

My specific questions to Ieehoo were pertaining to:
"if I have a 72 Volt,75 Ah SLA pack, do I need 100 Ah LiFePo' or 200 Ah?"
"Do you offer a battery mangament system and charging systems along with the battery pack for a turn key, matched sytem?"
"can you provide pricing?"
I spent some time expressing the need for examples of their batteries being used in specified on the road applications.

I look forward to hearing more from this manufacturer.

Maybe some forum catagories could be created for information pertaining to specific LiFePO battery manufacturers. Similar to the scooter catagories.

We now have a user base here on VifV using ping, A123, Thundersky and others. If catagories were set up for even some unproven suppliers, NO information would be just as helpful.

THANKS!

Re: what's quality for Ieehoo LiFePO4 Batteries

You MUST let us know how the pack works out. That is the size pack I would like for my Electric MC.
Any idea of the cost in US$? You must be excited to have a set on order. I think my range would increase to 75 miles or more, with an average speed close to 50 MPH. That would be excellent! The weight of my bike would not change. Fitting the 200 Ah pack would be a challenge.
Thanks!
