E-Sommet spare battery

[Dan31]

Been looking for an extra battery for those long trips out there.
Do you know where to get one?
I guess the smaller/lighter versión of 418W would be enough and more portable...

Pretty much any Shimano dealer can get you one, and lots of online sellers. You are looking at either the Shimano BT-E8010 Battery for the 504wh, or the BT-E8014 Battery for the smaller 418wh :

Thks R120...
Can we use this instead? BT-E6010
It can be found for around 400 quids, almost 200 less than its bigger brothers...
Looks like the connectors are the same but not the shape. Maybe we can use the internals and only switch the external box.

I don't know - I have always thought not, but can't give you a definitive answer

The 6010 doesn't look compatible with the mount the Esommet use, the 8010...
I found some info about the weights of the batteries:
BT-E8020 | 504Wh= 2900g
BT-E8014 | 418Wh= 2550g
Keeping in mind that there's almost no difference in retail price I think the biggest one is a better choice
