Here is the reply I received from CHINSUSA on my 100AH battery in one day, not bad customer service and honest detail, IMO.
They also said their 200 and 300 AH do have prismatic cells at this time but that the soft pack cells work just as good as prismatic cells
I am satisfied with their reply and customer service, not too bad.
thank you for your mail.
SKU: 12100-211227 is a soft pack battery, we have checked that your shipment is a soft pack battery.
If you can accept we can give you a 15% refund, if not we can give you a return.
Due to a shortage of prismatic cells, production is currently unavailable.
Production of prismatic cells will resume around June-July this year.
Sorry, currently only 12V 200Ah, 12V 300Ah batteries and Smart 12V 100AH batteries are prismatic.
We have some scratched 12V 100AH batteries that are also prismatic.
