Thank you very much. I just wish would have included the bus bars and screws like she said would be included. Must have been the pre-CNY rush to get the batteries out. :(
They may have dropped during transportation, or we forgot to put them in, we are very sorry for that!

I don't know this has caused you so much trouble. Please contact me via Alibaba, I could resend the busbars and nuts to you.

I've got a CITI card ..... Will have to look into the virtual numbers .... Sounds like a great idea for peace of mind.
I just noticed last order I placed with Amy earlier this month, that Citibank is affiliated now with Alibaba. They might have been before and I didn't notice, but I have had zero problems using a Citibank virtual card number with Alibaba or Aliexpress.

I ordered last night from Amy. She was very helpful. I do not expect to get the cells quickly given trans-Pacific shipping times right now, so I will be patient. My mental clock is set to end of July at best. Like my grandpappy used to say, "Son, keep your expectations very low regarding love, life and money so you won't be disappointed." Not the best advice I guess or maybe it was.?.?. He may not have been a very good motivational speaker.

Received and tested 4 Lishen 270 cells. First discharge after top balancing was cut off at 12.3v @30A, with the Aili montor showing 270AH discharge. cells were 3.132 3.137 3.146 3.153, 10 min after disconnect floated to 12.6 3.153 3.156 3.163 3.171 per BMS, these were slightly lower than measuring individually with multimeter (12.66v total). Using the values from Steve S voltage chart load/resting voltage points to 14% remaining, ie total 307AH...Not bad. In any case the cells exceeded the rated capacity and only were slightly unbalanced at very end of charge ~3.63v. Top balancing individually brought them within a few hundredths ... Only time will tell as to life, but the cells exceed my expectation as did Amy's delivery/support.(y), Thanks Amy & your supply chain.

I received confirmation from Amy last night that items had shipped. She sent photos of the cells and packages along with the test results. So, I ordered Tuesday night. Confirmation Thursday morning of being picked up for shipping. So far, this experience has gone well.

I hope Amy will have these LISHEN back in stock soon!

Is that the commodity cells or the grade A cells? I am pretty sure the grade A cells were always in stock. I just ordered some of the grade A cells in the 105AH size.
Grade A and matched. Also at a 30% premium which would be fine with me as they will be matched according to what we discussed.

I contact her via Alibaba on April 10th, she told me they are still not in stock, she said she will let me know when she has them in stock again.
Same here, I contacted her on April 22nd thru Alibaba, still not in stock despite showing in stock ready to ship. I’ve been reaching out to her since Feb 25th. Hopefully she can get a hold of some soon.
