New York? New York?? The COL (cost of living) index in NYC is 218! NYC is overrun with low cost delivery vehicles fielded by an army of wage slaves that are not having a quality life experience in the Big Apple. I am pretty sure the battery pack I bought for my cargo bike mid-drive project cost double what that entire melted bike in the clickbait photo cost. As said earlier, its the CHEAP batteries that need to be feared, and rather than buy an $80 battery pack and a $250 bomb disposal unit to charge it in, why not buy a $300 battery pack? <shrug>. I also bought a quality charger that costs what CHEAP battery packs retail for. It will charge to whatever you want, 80, 90, or 100%. For long term storage it is not recommended to charge over 50% and unlike using or charging a battery pack, for storage of a li-ion battery, as cold as possible is what e-bikers in the know adopt. Freezer storage of battery packs NOT IN USE can extend their life by years. FWIW.
