How to test battery while IN THE BIKE

[Desdinova]

Does anyone have any hacks for getting to the battery terminals to charge, or jump, or anything more than putting a meter on it, without pulling the battery which is a Royal Pain !!

Maybe someone can share a picture of their battery compartment with the battery in?  I've only replaced the battery once, and replaced with what was there, but there is ZERO room and I'm wondering if maybe the wrong "style" battery is in bike and as I bought it new, I just never knew.  I mean seriously, it takes a bit of clever acrobatics and three hands to even take the battery out because you have to lift and hold it, to get to the terminals.  

I've rarely had an issue, but I thought while I need to do some trouble-shooting of the start issue, maybe a better make sure I have the right style battery in there while I'm taking it out anyway.

Thanks in advance.

Hi, the battery compartmentent is indeed rather small. That said, I just put two small crodile clamps on the poles to re-charge when necessary. 

 

EDIT: + clamp being isolated

@Desdinova, Here is an image of the battery/underseat with some modifications. There are "junction blocks" added behind each of the battery terminals to reduce the of ring terminals and add accessories. Others ( @Tomchri) have added "L"-shaped brackets to the battery terminals to bring the terminal stack paralell to the top of the battery and more accessible.

Also, the battery basket, in the factory location, stands the front of the battery quite high beneath the seat making the terminals even harder to access and allowing the seat to put pressure on the battery under the rider's weight:

 

Moving the front mounts of the battery basket beneath the subframe addresses this. Below, relocated battery basket in the foreground, prominent front corner of the factory position visible on the Rosso Mandello in the background:

 

P.S. - Another image with the battery basket in the factory position (front mounting tabs above the subrame) showing seat damage to the battery hold-down strap:

Here is a good discussion of the issues and several solutions:

I just bought an Earth-X LiFePo4 battery. Tiny. Powerful. Not that much more $ than the others and produced in Colorado by a company which makes FAA certified aircraft batteries. ANYTHING to lighten these beasts. And it provides flexibility in location for easier access to charging/monitoring, etc.

@Desdinova it seems you have recognised the value of this move. For anyone else, do this. It was recommended to me by a highly knowledgeable member of various German forums. Looking at the situation under the seat made it immediately obvious that this simple mod was very sensible and useful. If you haven't done it yet, do it soon.
