Thanks Dick,

I appreciate the guidance.

If I stop a charge before it reaches the target capacity (be that 80%, 90%, or 100%) because of the need to set out on my home leg, will that compromise battery health eventually because balancing wasn't completed during the later stages of the charge?

I suspect that the answer will be yes.

I wonder then if it might be better to select a charge target that is less than 100% rather than cut the session short if choosing 80% or 90% would allow time to complete cell balancing and still provide sufficient charge to get me home?

Your a star!

Hi,

I am making regular longish out and return trips on my Radrunner where I need to recharge before setting back on the return leg. Sometimes I'm a bit pressed for time before heading for home, and I have wondered whether it is safe and technically feasible to 'rapid charge' the battery before setting off.

I have been using the 48V Advanced 300W Luna charger for some time now, which provides switched options for charging to 80%, 90%, or 100%, and for charging at 1A, 2A, 3A, 4A, or 5A.

My usual charge will be to 80% unless I am doing my long out and back trip. I also always choose to charge at 2A to match (more or less) the current that would be delivered by my origional / supplied RAD charger.

So I'm wondering; would it be okay to charge to 100% at 3A?

I appreciate that this could have a detrimetal effect on overall battery life evventually. I would be interested to know how quickly that might happen. But I'm more concerend about overheating and fire risk, and / or the possibility that the battery BMS would struggle to handle cell balancing at that current.

Wondering what you good people think?

I'm looking for a cover for my Radrunner.

The unusual dimensions of the runner has made Web searches a little difficult, so I was wondering if anyone can help with a recommendation?

Don't mind whether it's waterproof or not, light or heavy weight, I'd simply be happy to find something that fits.

Hi,

I'm new to the forum (a Radrunner owner) and I hope that I'm not posting on a topic that has been raised and excluded previously.

I have fitted an Eggrider v2 to my bike and I'm refining its settings presently. I would love to share experiences concerning how other Rad owners have used this non-Rad modification.

Would it be ok to post on this topic?
