I sent 2 back to china for them to test so they can see that they are not up to spec.Hi
Any update on these batteries?
Regards
Out of 100 I purchased about 64 were above 41Ah about 25 were in the 35-40Ah range and the rest were below 35.
I'm ordering 150 more from another supplier and I already came to terms with them the process if cells are not up to spec. Plus I have the means to test them all now within the 30 day Alibaba return policy.
I sold all batteries that were above 40Ah on e-bay to help offset mu cost of shipping.
The others between 35 and 40 ah I have deployed in a 2P12S configuration as storage in my home test system.
It is working flawlessly so far.
estimated capacity is 72Ah but I have not tested the full bank yet.
Did you order cells? and do you still need help with a testing system?
Just for fun I have this available on the web. It shows my test bank voltage and PV stats PV and Battery monitor.
Hopefully in the next few days I can track power in and out of the pack.
