Has anyone purchased/tested the lifepo4 310ah from aliexpress yet ?

[smithgeo]

I have 12 of these in my cart right now and concerned about the quality. Anyone know if the Oye Store is a good supplier before I drop $1575 of my hard earned money? Thanks!

For what it's worth - I was told they are brand new, grade a cells... Time will tell. At least my credit card has good insurance! They notified me today the package had shipped, and provided a UPS tracking label. Expected in 30-40 days.

I got 16 310s from Shenzhen Basen in under a month. Trying to figure out the best way to capacity test them now. Here's a few photo's. All sharpie is from me testing voltage upon arrival. I only have a multimeter currently.

Thanks. So far no sign of dented cells or any damages? Lots of people are complaining about Basen regarding to damaged cell and how they handle the issue, I myself do not have problem dealing with the issue I had on my first purchase from BASEN, my contact is Gloria.
Looking forward to see your test result, BTW, good price.

I had one small dent but it didn't cause concern. I told Aimee Lee and she said keep her posted if anything is off. At that price it was hard to say no.

Are you building yours for an RV? I'm nearby you in Crofton and starting a system for my 5th wheel with 310aH cells. I need to figure out a BMS now.

I have a tax sale pending foreclosure in HarCo. Once complete I'll have a 30x40 metal shop to outfit with solar.

I do about 2 hours of research/learning a night. A BMS is the hardest thing for me to decide on right now. Overkillsolar is sold out of Will's latest recommendation. Daly can't be delivered until May. Electrodacus seems a little too complex for me for a first build. I've seen good/bad reviews of Chargery - But I can't easily find prices or info on that one.

You might be interested in these JBD bms. I’ve just received mine yesterday and they are big, looks well made.

Are you using a REC BMS?

Not yet. Been researching in preparation for building a Ford Transit T-350HD Camper Van. The REC BMSs seem like they're The Bomb though, Extremely Flexible. It's what I'm going to order.

i mean the cells. I believe there are many on this forum who are very curious about the catl 302ah cells =)

Here is the datasheet for them but not sure how relevant it is if the grey market ells are cells rejected by catl

Ordered my REC active BMS yesterday... pricey, but should be everything I want and need...
