Don,
I agree that LiPo batteries have an excellent power to weight/volume ratio and their lifetime is impressive, but the current prices are still prohibitive.
The website you quoted prices their batteries at $3.50/AH at 3v. To get 48v, you need to multiply that by 16 (3 x 16 = 48), so 48v is $56/AH. So from ilovebikes, a 48v 100AH battery would cost $5600. This price seems typical for the plug and play resellers. I'm trying to see if I can find a way to cut that price in half from available suppliers in the US. I'll let you know if I'm successful.
Just to gauge the current market; if I could supply a 48v 100AH LiPo battery pack for around $2600, would any of you actually buy them? I know that this is about twice what AGM costs, but the weight should be about 35% and volume around 50% of lead acid.
Does anyone here think that this is a reasonable price point?
Fair winds,
