New cells from Winston are LiFeYPO4...

Spoke to several people at Balqon and the LYP batteries are actually LFP. It appears these was a mix up in the part numbering. Not that this has a major bearing on performance, but I thought you all should know what you are NOT getting.

I ordered 40 , 90ah cells on Thursday and they arrived today (Tuesday).

That's a 2000 mile trip. Not bad.

were they banded or did you get the banding stuff to do it?
LOL probably the best mileage you will get from them.

No they aren't banded and I did not get the banding stuff to do it.

I wonder if zip ties would work. I've got some big ones.

Balqon>Steven says "Swelling of the battery usually happens when you over charge these batteries. We have made a 12v pack out of the 260ah batterys and have had this with no clamping at all for the last 2 yrs., and have had success with no swelling."

They dont need to be banded. If they swell up you are doing something wrong, usually overcharging.

Well, it was an interesting transaction, but I finally received my batteries from Balqon. They seem like a good company but they made a lot of mistakes at first. I was trying to purchase ninety 100Ah batteries. When I first tried to purchase batteries, their website wasn't working right. By the time it would let me check out, the prices had jumped. I emailed them and asked if they would honor the original price. The return email said they would and showed me how to order them for the lower price. After I ordered them, I received an email saying they thought I wanted 90Ah batteries. They said I could get 90Ah right away but 100Ah would take at least 8 weeks. I told them I could use the 90s.

They only refunded about $300. I told them that if I couldn't get the lower price, I would rather wait for the 100Ah. About that time Steve, the Production Manager got involved. He figured out what had happened and fixed it. I wasn't going to buy the jumpers from them but ended up using the difference in price to buy them rather than get a further refund.

The batteries arrived quickly and the shipping charges were very reasonable. I was surprised by two things about them. One is that they don't come with the bolts and washers. I thought I had read multiple posts that it is normal to get them. The other thing that concerns me a bit is that all of the batteries are basically fully discharged .2 to .45 volts. Again, I had read that most batteries are shipped partially charged and at a very stable value between the batteries. Now I need to look into the best method for initially charging these. It took about two weeks to ship from the time I placed the order. They said that was because the batteries were being fully tested so I have to assume it was intended to send them "empty".

(Sorry. Just found out my nice Fluke meter went bad. Thanks everyone).

Lots of work ahead of me now. I'll let you all know how it goes.

.45v That doesn't sound right to me at all? If you plan on keeping the things you will need to charge v e r y slowly. Likely a 5w lightbulb charger or a fixed amperage/fixed voltage power supply.

My thought would be to contact them and state that the batteries are DOA.

Cheers

That's basically discharged to zero, which is never good, and below their specs for the low voltage limit. Double check your volt meter readings and then contact Balqon immediately.
