Nice, like it Evo!
i've been having a bit of a panic lately...but that was the perfect thing you could have said...
(only because i know Snowchyld advised lipo and a 5404, Thanks for all your advice man I know its sound! I heed all advice of those more experienced at a subject than I. plus i might wanna talk twin motors soon:)
you see I got the headways and thought i had made a mistake even though i did pick them because i presumed the safer Lifepo4 was better and the 42160 16AH i ordered seemed really good for the cheap price i paid...I got the diy kit, and have nearly finished building them in cylinders to fit snug with my frame rather than in a big box.. The fact people were explaining it in cute Chinese as "Now no explode, will no fire" was good...hehe
just to ask, how hard would it be to now run them along side a a123 pack i build? or is this impossible? im sure it can be done but you would end up maybe matching to the lower power batteries (the headways?).. its just i have an innovative structure design to make a very high density battery in the perfect shape and space for my frame, the cylindrical cells wont fit quite so well, (i think the main complaint of headway packs?) i wanna keep the headways as my design actually incorporates the two form factors, just a123s would not fit, plus i hate squares!! the enemy of organic beauty!!
also i'm a very unhappy Ninja as max can't get me a 54xx now, he tried but I would have to order another 50, and although i want one really bad i cant justify 49 replacements

haha
id advertise another bulk buy but i doubt id get 50 people they seemed to struggle last time in europe anyway....maybe when a vid of the speed of these things is out...hehe
aslo contacted hyena as he mentioned spares but he has sold the two he had spare i think! my last hope is Ilia but i only have the address support@e-bikes-sf so will have to hope he gets it...
both max and hyena have got/can get the hs5140s an upgrade to the hs540 which i presume are quick but they are not as beefy as the 54xx's so cant take as much heat or abuse for a long time,
i still have the cromotor hubzilla to choose from as it has just ran over 60mph on 21"s so if you ran ot 26" maybe that would be fine too... its just compared to the 54xx they all seem a bit of a make do or consolation prize...haha.
I will try ilia and wait a few days for the answer then make a choice on my second choice

that's why i might wanna talk twin drive!!;)
just a bit gutted i cant build the super fast street tourer i had planned..could still be a fast street tourer just not a super fast one..
