Back up battery

Okay, so I have been snooping round for a bit. Darn near ordered a back up battery from Ali Baba, but wanted to wait and see who can help here that actually have a e fat tire. Mines a Juiced with a 52v battery. Need a backup for on the road as I am trying to make sure I don't run out power somehwhere in hills. Please tell me what everyone does. Thanks
 
I've also wondered about a lightweight (with resulting in low range) backup to carry for extending range, but I've not found a solution yet...

I would also be interested in the answer. I looked at a spare battery and it was very expensive.
 
I have seen portable “power outlets” that were essentially giant power banks. You could carry one of these and charge your battery when not in use.

I am not sure about charging your battery while riding around and using it, but maybe that is a solution to be looked into...
 
I've been toying around with one of these DeWalt 60V batteries to use as an emergency ebike power source.

It's rated at 60V but I believe the cell configuration is the same as a 52V battery. It has a 12 AH rating (for 20V tools) which in theory would give me around 10 - 12 extra miles on my 52 V bike. At 3 pounds, it can easily be carried in a trunk bag or pannier. It's a bit pricey at $200 but still much cheaper than an OEM battery. In my case, I already have several laying around which I use for power tools.

The trick is constructing a connector / adapter cable to mate up with the connector on the bike. So far, I haven't had the time to work on it.

I posted this thread 2 years ago on the subject but haven't spent much time on it since:


Maybe over the winter when I won't be devoting my spare time to riding. :)
 
It would be great if we could get access to the electric car chargers that are dotted all around the country.

The short answer is, we do have such access. The topic was discussed in the last couple of pages in this thread:

Hi There. Is this information relevant to riders in the UK? Admittedly I am not the best at searching a topic on-line. But I can't seem to find any public ebike charging points in Scotland. Do any of you chaps know if I can buy an adapter. I don't fancy making a DIY one. I will probably melt my bike. o_O

Sorry, I didn't realize you are located in Europe. These sites may be of some help though:



Scotland uses the Type 2 CSS and CHAdeMO connectors which are different than those discussed in the thread I linked. An adapter to convert these connectors to the one on your charger may exist but it is likely you would have to make one yourself.

***EDIT***
This post go me thinking again about my backup battery idea. It turns out someone is marketing an adapter for the above DeWalt 20/60 Flexvolt battery:

Since I already have the battery, I ordered the adapter and wired it to my 52V Pedego Interceptor. It works well, giving me about a third the capacity of the OEM Pedego battery. On an average ride, this equates to around 18 extra miles. I tapped into the main battery connector inside the controller housing and ran the leads back to my rear rack bag.

So you are charging the battery with an extra power bank while you ride or while it’s in “rest”?

No, I'm using the DeWalt battery to power the bike with the OEM battery removed.
