Pay more now, less upkeep and risk ever after.

How long would it take you to save the difference between Lipo and a 18650 pack?...
Do you have a link for a US supplier using 18650 cells? I couldn't find one. If the prices between those comparable I would definitely go with Li-Ion, but everywhere I checked it was overseas delivery or bust. IIRC I think I found a listing for someone building to spec but they were mucho expensive also.

The best 18650s have 1.75 times the watt-hours per gram as hobby LiPo:bobotic said:From everything I've read LiPo is clearly the way to go in terms in power density, current output and price.rsilvers said:If LiPo was the way to go then Tesla would use it. Though maybe they just don't like the fires.

As for price, I paid $407 delivered for 48v 20Ah. They just raised the price to $425.

LiPo:

A pair of them would be 710 watt-hours for $270.67 delivered. That would be like $366 delivered if it were the same capacity, which is not much cheaper than $425 considering that the 18650 pack comes with an aluminum enclosure, a key-lock, a mount, a BMS, a charger, and basically no risk of fire. I can't think of any reason to use hobby LiPo unless you are drag racing and need a very high C rating.
