Lipo chemistry & mah

[Robinev]

question what’s the highest capacity lithium battery that’s currently available today that you’ve put on a bike?

LiPo is not the type of lithium battery most ebikers use.

Are you only asking about packs comprising LiPo batteries, or lithium in general, all chemistries?

Also, you do know that "battery" can mean sub-pack units right?

So for example, 6S 6.3Ah LiPo packs can be connected together in whatever quantity you like, in serial to go to higher voltages

or in parallel to get to high Ah capacity

usually both?

So are you asking about cell size?

Sub-pack unit size?

Or total pack size?

Finally, would a cargo rig designed to carry 500+ lbs long distances, still qualify as an eBike in your opinion?

I think what are you asking for for is energy density of lithium batteries to be used in e-bikes. Usually Li-ion kind is used for this application unless you are doing something out of the box.
You need a medium lithium discharge rate cell (high discharge for Li-ion), you can find good quality cells with an energy density around 200 to 220Wh/Kg. That is at cell level, final pack energy density will be lower as you have to add enclosure, connections, BMS...

I highly doubt that its anywhere near the top end, but my proton has a 72v 50ah (3.6kw) LiFe battery as an available option. Was a bit out of my price range though so I stuck with the 35ah version.

I feel like Goldie locks when shopping for lipos trying to find that sweet golden aspect ratio. I only wish I could try them for free like in the fairy tale.
