Hi michael
i have been living and working in china and taiwan for three years plus - getting a straight or simple answer is never easy. i suggest you go with a reputable dealer in your own country for piece of mind and future backup.
PS i work in the quality control line of work in boat building and we import 90% of ALL installed items such as machinery, pumps electrical items etc
there are deals and deals but eventually one way or another you get what you pay for for most items.

Subject: [Electric Boats] trying to get prices from Alibaba contact (a rant)
I've been trying to get an answer from a Chinese company that I contacted through Alibaba. The question was pretty simple being as I found a photo, description and specs for what I thought a suitable product on one of the Alibaba web pages.
I asked for the price of the unit displayed which was a 48v, 200ah LiFePO4 battery pack which they claimed would make a great EV power pack. I asked about the functionality of the included BMS in terms of high and low cutoff at the cell level and if they used passive or active or none at all balancing.
So far the optimum-china.com folks have asked five different sets of questions and I have patiently responded all five times but to this point they have not provided even the hint of a price. Their latest with no price give was that perhaps I was ordering a larger battery pack than I needed?
REALLY a waste of time talking to these folks.
Being as all manufacturing is being moved off shore I will probably have to try again at some pont but this particular group is no firmly on my "S" list. They simply seem incapable of answering the very strait forward question "how much?".
