Thanks for the link, I checked out the website but your batteries are twice the price I paid for A123s. I was hoping to find some large battery packs, i.e. 36-v 12AH to 48-v 40AH but there were none that large, so I started looking for a Battery Management System (BMS) to be used with your cells and again I was disappointed. If I missed something please let me know because I would love to find a good source for batteries, chargers, and Battery Management Systems.

Thanks,
Grandpa Chas S.

hi Grandpa !
the US Website will be ready in the following days, with adapted prices...
when VAT will be removed and discount applied, the price of 26650 (A123 M1 size) will be near 11$....I think it is not as bad face to increaseing prices of Dewalt packs !!!
Anyway, I am not ready for big charger and BMS, but can ask my factory to make big packs like this one (24V - 10Ah)

Waiting for your new comments ;)

Maximus

We will all be looking forward to seeing the US website. Some items we will be looking for are;

Individual cells at a discount based on quantity ($11.00 is a good starting point)
Separate BMS
Charges
and of course complete packs with BMS
Maybe some Pack & Charger combos at a small discount for both.
Please include sizes (H x W x L) in both Inches and Metric also Weight in Pounds and Kilograms for each item as this is important information for the E-Bike world.

Thanks again for helping us with this information,
Grandpa Chas S.

Ok, I have a question for you. How much for a 60V 2kw pack? with bms? I want to be able to charge it in ten to twenty minutes. Im not to worried about if its 110, 220, 50amp 100amp. I just want to know if you can offer me a pack that can be charged that fast with that kind of capacity. Let me know what you have. I will probably be calling you on monday.

Thanks,
Elijah
