Do you have a link to the EM3EV pack? I don't see one that discharges 50A continuous (that's pretty high for a 20Ah pack), unless you special order it with specific cells. It's likely a special order pack due to your 50A requirement. $700 or so US. I'd go with something using cells like the Molicel P50B or similar high discharge cell.Can anyone reccomend a battery that fits these specs and can be purchased to the uk (dont mind waiting if have to import) for around £300. have looked at em3ev but is going to be about 500 EUR to ship to uk. was thinking about UPP but saw too many bad reviews so have been put off. Any help greatly appreciated
