    NMC lithium batteries

    Does anyone have facts about lithium NMC battery chemistry for e-bikes versus LiFePO4? From what I've read, Li-NMC has the best energy density of the currently available lithium battery types. That is, it packs the most energy at the least weight. For example, this battery in a tube...

    Cycle Analyst V3 preview and first beta release

    I notice that your list of chemistry selections doesn't include Li-NMC batteries (also known as NCM), which are new. They have higher energy density than LiFePO4, a little less cycle lifespan, but good safety. They are lighter weight for the same energy capacity. The all-electric car...

    Can a 24 Volt Bike Take Any 24V Battery?

    Here's a description of that bike when it was new: http://www.electricbikes500.com/electric-sierra.html. It uses SLA (sealed lead acid) batteries, which are relatively cheap and easy to obtain, such as at a BatteriesPlus outlet store. You'd need to take in the exact batteries you pull from...
