Has anyone successfully (or even tried) fitting an aftermarket battery pack to their bike?
Seeing as tec packs are so thin on the ground, how feasible would it be to make your own packs.. Eg there's loads of videos on YouTube with guys getting 36v packs by 10x5 configuration and getting 10.5-11ah like focus themselves.
Is there anything stopping me from purchasing higher capacity cells and potentially getting a 500wh(or even625🤔) pack on the downtube?
Apologies if this turns out to be a stupid question as I've very limited knowledge on the subject other than the above.
Appreciate any knowledgeable replies👍

I wouldn't think it's as simple as just plugging in another battery, I'd assume it would have to 'talk' to the bike computer etc...

I'm waiting patiently for the Trailwatts battery but not holding my breath if I'm honest :confused:

I'd like some clever person to see if the internal battery with, I assume 18650 batteries, can be upgraded to the newer higher capacity 21700 batteries :unsure:

That would be even better... Id love for a 625wh pack for the downtube or even a replacement internal pack too for long range bikepacking or big days out in the lakes etc
