When did you place your order? Did you have your batteries shipped by air or sea? I'm about ready to give up. To many uncertainties - too many ways for a beginner to get screwed. Alibaba won't accept my credit card anyway, and the credit card rejection appeal system is non-functional.
I think I'll just give-up and order from AliExpress. Much more more expensive, but every transaction I've made over the years has been simple with no surprises.
Yes,dealing with Chinese companies you need to be aware that there are "Always" surprises.
Sometimes small, a Nikkii why suddenly is Amy
Sometimes huge, like my mppt inverter who was different model and was defective
(I found out after installation, it charged my 48v lead acid array with 78v.. $ 4.500,- on batteries waised... now 1000kg old lead)
Dealing with "respectable companies" like Victron (the Netherlands) ain't guarantee also.
Other member on this forum lost 14.000 on batteries due "Specialist" problems.
For me I ordered the 152Ah, and payed via bank account.
Yes, I take a risk.
After the loss on the lead-acid, I don't have much other options.
I needed cheap and good.
For sure, I did my homework on this seller!!
The 152Ah are new and look like A grade. Capacity test, I'm waiting for my delayed tester.
My test from 4x 3.3 volts, 70% full with simple 12v 100w lightbulb went OK (should be about 1400w)
10 hours without issues. Then it was bed time. I didn't want to go below 2.5v
they are now recharging.
