Anyone using a power bank?
 

Most of my motorcycles are in a couple storage units right now.

Unfortunately there's no power in the units for a battery tender nor does the owner allow a solar panel charger.

Usually I rotate riding them often enough I can bring them home and charge the battery overnight and then rotate to the next one. Most have battery tender harnesses on them so very easy to do this.

I also have two cars in storage units with battery disconnects for the negative battery posts. They work fantastic - both cars started right up for me today. But most of my bikes didn't because the batteries didn't have enough juice.

Do I install disconnects for the motorcycle batteries - it would have to be one on a loom to make it easier to access the switch.

Or buy a power bank and hook up a battery tender to them on a rotating basis. The disconnect, if it worked, would be less hassle.

Looking for any suggestions and input here....thanks!

And before you say I should be riding more often...yeah you're right. A broken rib, hurricane, and family stuff has a way of slowing things up in that department. Hoping to get back on track soon though.

Thanks!

Found a YT video showing how a power bank would work for my application.......pretty nifty!

Pull the batteries and take them home?

Battery pack looks easier. Maybe two and swap them out occasionally?

The owner won't allow a solar panel but a battery pack is OK?

Last resort.


Use power bank and charger. I already have SAE leads on the battery so easy peasey.


Solar panel would have to go up on the roof or on the front of the unit. They don't want anything electrical attached to the building. Power bank is portable.

Ah. I was thinking of a smaller unit.

How small? I have some that are only 24" and you'd still have something 2' wide attached to the building.

Anything smaller than that wouldn't really be practical - nor allowed.

I really think the power bank is the answer here.....just curious if others are using one and what their experiences with them is.....

How about just carrying a lithium jump box. Hook it up and start the bike....ride.

Is the battery pack meant to do this (didn't watch the video as I'm at work)
Some go boom

This^^^^

Battery inverters are not practical IMO. If you want to spend that kind of money feel free.

I would buy the jump box, or a good sized AGM car/truck battery and connect that to your bikes on a rotating basis.

Do motorcycles have much parasitic draw? In my experience batteries maintain their charge pretty long when completely disconnected, I think a disconnect switch maybe your easiest bet.

I pull all my batteries for storage and assuring a good connections upon reinstall.
Batteries store well but connection corrosion never stops.
Also acts as a theft deterrent in rural AZ.

I just got an 1200 watt Ecoflow Power bank with a 120W solar panel. I'll probably use this in place of my gas generator most of the time during power outages. I haven't put it thru a real test yet, but it seems impressive so far and could easily run a trickle charger for many days.

You are inverting DC to AC then back to DC to keep a battery charged?

The power bank will provide AC for my battery charger.

The battery charger will charge my motorcycle battery.

For those saying just use a jump box. If it was an urgent situation sure. But it's not urgent and having a fully charged battery is the gold standard here. Besides.....when you run a bike with an undercharged battery.....it makes the electrical charging system on the bike work harder. I don't want that to happen...lol....

I want a fully charged battery from the moment I turn the key until I'm done riding.

The power bank arrived today and I will use it tomorrow and report back.

Thanks to all who responded!
