E-Bike Battery Cell Replacement


It’s better than buying a complete new pack. Why? Because there’s a guy out there who will replace the individual cells. I’ve been quoted a price of £140 or a possible upgrade of £170 depending on how many cells and their configuration (series and parallel).

So i think what you have there is 10s4p battery pack or 10s5p
I will be able to make it like new 10s4p (13.6AH ) for 140GBP


or if it is 10s5p battery pack I can fit in 17AH ( 170 GBP )
( i will use Panasonic NCR_B ) cells
and each of my batteries will have a 2 year guarantee 🙂

And there’s also a bluetooth upgrade for £25, this will connect to your phone and it will give you precise data about the individual cells and the battery pack.

I can’t speak for other battery packs, but I know the packs from Halfords for their bikes start at £400 for a brand new pack.

So now my old pack, 3 years old, is getting a little past it, I’m really tempted to go for it, I’m just a little skint right now and I can’t afford it, at least not this month.

Just let Mat know The Bionic Cyclist sent you 🙂

Mat has also made me aware of the the other things he does:

Hi i can recell/Repair all type of batteries but i’m not doing flat type of batteries ( rear battery packs)( flat one ) or small bottle batteries ( which have 3x levels of cells )
also i have ready to use battery packs in blue thermo wrap ( with LCD /or Smart BMS ) 36V
+ I can make custom size ( Triangle/Rectangle battery pack ) 36V-72V (up to 3000W/5000W and more )
+ 36V custom battery for full suspension frame bikes
+ Just welded packs DIY (without BMS )
+ 24V – 48V Battery packs for Powerwalls / Campers / Chargers 1.5Kwh/2Kwh/3Kwh
+ 18650 cells for Sal

So that’s quite a range of different things in all.

GoPro Fusion Review

I’ve made a post on the forum and it’s not pretty, I like the hardware, it’s excellent. Unfortunately the software is a disaster. The camera has been available for over 2 years now, and gopro has done nothing to improve the situation, and they’re preparing a new 360 camera for launch. Unless they launch a new app for editing 360 videos that’s as good as the Insta360 One X app, then I can see this being a disaster for Gopro, and rumour is that they’re struggling to stay afloat.



This video shows how easy is is to use the Insta350 Studio to edit and reframe a 360 video. Sadly the Fusion requires three different types of software to acheive the same thing.

1. Gopro Fusion Studio to stitch the 2 cameras together (even on my beast AMD Ryzen 2700x, 16GB RAM and all SSD drives it takes hours and hours and hours just to stitch them.

2. Corel Paintsop Pro 2019 for Tiny Planet photos. £55

3. Adobe Premier for the video, keyframing and reframing the views. £20 per month for as long as you’ll use it.

The insta360 Studio does all this in the app that comes with the camera and for free.
