Multiple e-bikes, one battery?

[Taiwwa]

The issue of battery wear in e-bikes worries me. My bicycles can go through periods of infrequent usage. For those with multiple e-bikes, do you just move one large battery pack between them? That way you’re only wearing down one battery pack at a time.

Assuming the bikes are similar power, (not surpassing/taxing the BMS limit) I would move the battery around as needed. If it’s just you riding multiple bikes, then no matter the bike, you’d still be riding with that same battery.

I have a Rad Rover and a Rad Mini. I don't ride the mini all that much but since the batteries for both are identical I simply alternate batteries mostly in the Rover so both batteries are in regular use.

You should be mindful of the wear and tear on the connection. On my packs, I have XT90S connections on all of them. So I don't want to cause any wear on a connector that is not easily replaceable and mission-critical (a hot connection to a live battery for instance). What I do is buy (or make) very short XT90 connectors, and put one on the controller side and one on the battery side. Then I unplug from the shortie 'bridge'. If something goes wrong on the short extensions, I just pull off that extension and put on another. I do the same thing with the XT60 charge cabling, for the same reasons.

I am not in the habit of taking pics of battery cabling so I had to go back to 2017 for this one. You use one of these on each side and disconnect the extensions. Let them be subject to wear and tear, not the main ones.

It is entirely possible you just have to factor in compatible voltage and how they are constructed and cradeled on the bike as well as the +/- connections.

I have bikes that are 36V and others that are 48V with batteries in a couple of sizes for each voltage and identical mounting systems for each voltage. That means I can move batteries around as needed. The 36V bikes all have standard aviation connectors. The 48's have a holder the battery can lock into. I don't worry about using them. That is what they are for.

I have 3 bikes which all use the same type battery. I have a total of 5 batteries but I usually use the same one on whatever bike I'm riding. All 5 batteries are 5 years old now and I find it interesting that the battery I use suffers the same capacity loss as those sitting on the shelf.

Yes, there is connector wear and the number of charge cycles to consider but so far, these have not been an issue.

In a similar situation, I have multiple bikes that share batteries, and one bike uses a weird 6-pin M23 type socket that is integrated into the frame. Can anyone identify the name of this connector so I can try to find one online to create an adapter. Or recommend where I can buy this?
