Hi Everyone,
Now that the weather has got much colder the last few days I've noticed a big drop in performance like last winter, no major problem as I really only get to ride at the weekends.
I've my LVC set to around 54-55 volts, so that might be a little low for 16S LiPo but its dying anyway so I don't care. But where I was able to get 5.8kw on acceleration now it's down to just about 3kw so that's a huge drop and really noticable.
As for sag due to cold, well that's hard to say because it's sagging badly anyway and it hit's lvc @ 54 volts from about 66.6 charged or even after using it a bit where it might really be 59 volts, but the overall amount of power has dropped due to cold.
Next year I'll have to replace it so I'm wondering what battery is capable of surviving the cold ? is the nanotech better able for winter use ?
Seemingly Renault's battery for the Zoe is not effected by the colt at all, performance wise, anyone know what they use ?
Is LiFeP04 effected much by cold ?
I'm looking at Zippy Compacts for my next battery, (I still want my fun when I can get out in winter), or maybe a cell-man triangle A123 battery ? But that probably won't do because I need more than 48 volts and LiFeP04 is bigger and heavier, Jesus I thought we would have had something much better than LiPo or LiFe when I bought my LiPo, the technology is sure slow to develop and even slower for us to get our hands on it.
Though LiPo is good power wise it hardly seems economical in the long term and am rethinking how I spend my next pile of hard earned, I'm also thinking if I will abandon Hub motors altogether and maybe the next set up will be far less demanding power wise.
