But...
Isn't a slow charge the better way (healthier for the battery pack) to charge batteries?
At least that's the way it was with old school tech.
In the past, it's been... The faster you charge, the more heat there is, and the faster you wear the batteries out.
Yes, the but charge rate depends on the batteries. The lithiums I use on my electric bike are rated at a max charge rate of 25 amps and max discharge rate of 100 amps. They are 5AH batteries, and the safe usable amount is around 66% of capacity. So if I wanted to charge them to full using the max rated charge rate it would only take me 8 minutes.
In my garage I charge at 5 amps, which I would consider a slow charge. So say if you had a medium charge rate of 10 amps and a fast charge rate of 15 amps, you would still be well below the max charge rate of the batteries and within the safe charging limits no matter which option you chose.
