Re: [electricboats] importing batteries wholesale

I sent this reply to this thread on Sunday but I never saw it post to the list so here it is again.  Sorry if it's a repeat...


I am certainly willing to believe many (or most) ad's are in the too-good-to-be-true category.   Are you saying there is more to the cost of these deals on sites like Aliexpress than what they say in the ads?  This one for example says you get (4) of the 280AH 3.2V cells for US $455 including shipping to the USA. 

https://www.aliexpress.com/item/1005001935502441.html?spm=a2g0o.productlist.0.0.2b087783z3GXDl&algo_pvid=3176c47e-b21f-4206-873d-aad1d01be060&algo_expid=3176c47e-b21f-4206-873d-aad1d01be060-4&btsid=0b0a555d16139597086837099ed79a&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

There are ads that claim to be from US warehouses too.  Any knowledge about that out there? 

 

There are many examples on Youtube of people getting these batteries and testing them.  Will Prowse has one here:

He did not mention importation difficulties.  

There are several others - search for 280AH 3.2v

I am ready for my reality check....

Thanks, Dan Pfeiffer

But to more precisely answer the question, it's about 50% cheaper, and much more so depending on which domestic option you choose. 

 

For example: 

Here is a relatively new offering on Amazon, which is really not a domestic option but another one of the CN companies establishing a storefront here, so they take on all the hassle - it's the cheapest I can find that will deliver to your door:

 

48v 100Ah LiFePO4 Battery Deep Cycle Lithium iron phosphate Rechargeable Battery Built-in BMS Protect Charging and Discharging High Performance for Golf Cart EV RV Solar Energy Storage Battery https://www.amazon.com/dp/B08G7YMWND/ref=cm_sw_r_cp_api_glt_fabc_AZCEDCA40SF3FMRQT42E

$1929. 

 

For a 600ah bank, that would be $12k. Pricing a similar size from Alibaba and including customs and shipping, renting a truck, and driving around the warehouse district, it was 45% of that. 

 

Not exactly apples to apples, but hopefully illustrative.  Now compare to battleborn, and it's 1/4th the cost.  On the other side of that battleborn have a fantastic reputation, years of proven performance, and rock solid guarantees.  There's a reason the price points are where they are. 

 

An interesting domestic option maybe the Dakota Lithium batteries, mined and manufactured in the US, and seem to be reasonably priced ($899 for 12v100ah - 600ah would be almost $22k).  Still more than 4x the price of my 600ah bank, but if you want a domestic source and the confidence to be able to return it, that looks like a good option. They have a 48v charger that I'll be looking at for future applications - my noco genius charger is great but was expensive and produces an unpleasant whine when charging.

Good points! 

Yes, as per my original post, it's a risk and especially if there is some kind of problem. I relied on colleagues in China to do some research for me but nothing exhaustive.  In the end I decided that saving 50% (and this having 50% more range for my budget) was worth it in my particular case.
