From the surrounding countryside it looks like a citadel perched prominently in the river valley surrounded by mountains.

I have been across the border into Switzerland on previous occasions but never stayed. After collecting my new batteries and on route to my next destination, I took the opportunity to visit Zürich and some of the beautiful lakes on my journey south

Approaching 8,000 miles on my wheels I am conscious my batteries are nearing the end of their life. Genny's power unit is a Segway, complete with a pair of 72v 5.2Ah Lithium-ion batteries. Getting new batteries is complicated as they are consider dangerous goods. The movement of lithium batteries is subject to regulation by the International Air Transport Association. Segway going bust has added further complications to replacing my tired old batteries
After loads of research I have purchased a pair of ultra high capacity (UHC) batteries from a clever man who makes them in northern Switzerland. These are new batteries made with the same technology but a more modern build with higher capacity cells. To get these batteries I needed to drive across Europe and collect them in person
As I'm up for a road trip and COVID is starting to settle, and having been doubly vaccinated the world is opening again for me. Packing my VW van with mattress, cooker and of course my wheels, I set off for a grand tour and to collect my new batteries
These batteries are built into refurbished cases and there is a trade-in on the old batteries. They are made with a bespoke battery monitoring system that works in a slightly different way but still relies on the standard Segway charging interface. The usual charge indication shown on the Segway infokey reports it's level based on the use of the battery and measured by a built in shunt. The following image shows Genny having used 1/4 of its capacity
The new batteries don't have that same shunt monitoring system and are more variable in how they report their level of charge however they have considerably more capacity. This is of course dependent on many variables like terrain and weight of load. I understand these batteries have powered a Segway i2 for over 92km which is easily more than twice the usual capacity of the standard battery. What I can say is that in my experience, I have been able ride for much greater distance than my old batteries would have taken me. There will be more on this in subsequent posts where I try these batteries on the Comino de Santiago
This graph compares the normal 5.2Ah (yellow), a newer releassed 5.6Ah battery (orange) and the new Swiss UHC batteries (blue) and indicates an increase in capacity of well over 200%
Delighted as I am with my new batteries I will probably revert back to my old ones till they finally die on me

Today I made 7000 on the clock with my Genny. It's actually probably more like 8000 as I had a long time with another Segway base unit installed but using the same batteries whilst my gearboxes were being restored.
I'm definitely getting less miles per battery charge but that is to be expected. Its not a lot less but I have a target that I would always meet on a familiar route where the first bar on the battery indicator would go. Nowadays that indicator bar falls about 400m short

Having purchased a backup Segway I have a spare set of batteries, however they are older and less capable of holding a charge despite having minimal mileage. My plan is to get a new set of non- standard custom batteries when Europe is open for business again after Covid.

I have found a company who specialise in all things Segway. The company is called PT Pro and they are based in Amburg Germany. They have been great at supplying various parts over the last year and I am starting to build a relationship with one of the engineers. Isn't it amazing that many Europeans speak fantastic English - puts us all to shame
PT Pro have a great website where they have many resources and are able to offer services that aren't available in the UK. Things cost a lot and postage from Germany seems to be expensive but they are quick to process your orders and parts arrive when they are due. There are many simple repairs and modifications that can be made by someone with very limited knowledge and simple tools. I have highlighted some modifications in my Genny Mods page
magnetic drain plug and gearbox oil. You will need one magnetic drain plug and 70 - 80ml of oil for each gearbox of which there are two on your Genny
PT Pro have have great information about the care and repair of Segways particularly in relation to GEARBOXES and BATTERIES, They can also sell new wheels and tyres as well as being able to repair those delicate buttons on you Infokey
Here is a picture of the corrosion on my Segway driveshaft after being sandblasted to remove the rust. The pitting will stop any effective seal leading to a loss of oil which is not a good outcome for a metal gearbox.
