I have RR5 with Tannus inserts.  I've had two flats recently (Front and back) and was just using the supplied inner tubes.  I would like some recommendations on replacement inner tubes.  I'm 26X4 tires.

Considering swapping out the Tannus for Mr Tuffy + flat out based on some posts i've read. 

Even if I swap out the tannus, still looking for replacement inner tubes.

OR do I have to match the inner tube size to the type of add'l protection (Tannus vs Mr Tuffy)

Thanks

I had the same issue.  I accidentally touched the charging port with the key and it stopped charging.  All I did was replace the 5A fuse and it's been fine.  Look at my name and see my other post about this issue. 

Now I carry spare 5 and 40A fuses.  Was a very simple fix. 

Have to appreciate the fuses built in - def protected the battery.

I've had my radRover 5 for about 18 months.  Had one flat two months ago and then another flat a week later.  Freak coincidence.  Flat #1 was a puncture, had to replace the tube.  Flat #2  I could not locate the puncture but replaced the tube.  Both repairs were done by certified bike shops. 

The first repair shop told me I was running my pressure too low and was told to keep it at 30 psi.  I ride several times a week.  Based on the Tannis site want to clarify the pressure Tannus recommends:

What PSI should I run:
Tire pressure is a personal preference depending on size of the rider and riding conditions. However, adding Tannus Armour does allow you to run lower pressure which gives better control, and comfort. We recommend starting out 5-10psi lower than what you normally ride and go up or down from there based on the ride feel you enjoy.

Does it compress after use?
The armour will compress some after it?s installed depending on the pressure of the tire. The higher the psi the more condensed the Armour will become. If you wish to keep the Armour as thick as possible then maintain a lower psi. You may also deflate your tire if you?re not going to be riding for a longer period. This allows the Armour to rebound back to its original size.

Anyway, it's been over a month since the repairs and i've been keeping the PSI at 30.  So far so good.

same thing happened to me today and brought me here.  Replace the 5A fuse on the underside of the battery.  I have a radrover 5 but I think the battery tech is the same.  Refer to the radpower site for pix and instructions.  I think the 5A fuse is to limit the charging amps (Amps IN) while the 40A fuse is to limit the motor amps (Amps OUT).
