What size power bank to charge CUx battery
Looking for help as despite having an ev bike electronics is not my strong suit!
I may have an issue with charging my bikes battery at work soon, the noise of the fan isn't ideal (in an office) and I think from a health and safety point of view it may become a problem.
So I'm looking for options to charge the bike in the car park. I use about 40% each way, so I'm looking for a power bank that would be capable of powering my charger for 1/2 a charge.
Am I right in saying the general power banks made for phones/laptops would not be capable of powering my charger?
What sort of power bank do you think I'd need?
@328isport you would probably better off running the bike on an external battery pack rather than trying to charge your existing battery from another battery. There will be a lot of losses via an inverter and then again through your charger. Even an inverter is say 85% efficient so you will already need to make up that 15% loss by increasing your battery size.
@LHK, thanks, are you saying I'd better with something like this?
If not if you could give me an example so i can try to get my head round it 🙂
It's a CUx, battery says 60V 30AH on it. Sorry so are you suggesting I basically run a second battery, so when the main is getting low then i switch to the second? Issue is with the CUx is I'm limited space wise, there isn't space to run two batteries as I think there is in other models.
@LHK no I don't run a top box, I have a small storage section under the seat which is big enough for my charger, I was hoping I could get a compact battery pack that I could put in there or in my backpack, tbh even a 20-30% charge would do, as that would see me home with around 40% left, I wouldn't want to get back with much less than that as find the performance drops off a reasonable amount.
In terms of a battery pack, am i right in saying the type designed for laptops etc would not be capable of supporting my charger?
