Hello Everybody, we started new EV project. We are looking for strong AC Charger suitable for LTO cells. Battery is Yinlong 40Ah 21S1P. We would need high currents 48V 120-150A charger. Please could anyone recommend reputable manufacturer/seller from China with delivery to EU? Many thanks.
I found these, but they are 2100 EUR or more.

I also have offers from these, but I dont have any reference about build quality.

Many thanks for any tips.

Look at a used forklift charger, they would be a lot cheaper
 
I already checked them, but they are generaly for lead acid batteries. Not useable for lifepo4 or lto. Or Iam missing something?
Check the lead acid charger that the equilize can be turned off and check the open circuit voltage while being on is less than 21 x 2.8v = 58.8v. .
The lead acid charger should put out 57.6 v (57.6 / 21 = 2.74v ) and should be fine. I use a cheap 2 amp on to charge a 5kw battery. I am not worried about the time (50-60 hrs) , because it is for a ups
 
I'm tempted to build my own grab some scrap microwave transformers build a big rectifier and an arduino charging circuit maybe 250amps bigger means dedicated circuit? For lto batteries
