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?
