A non-RE question, but of at least peripheral interest, and I trust you.
In addition to my RE I have a Taiwan-made FlyKly electric scooter (FlyKly.com). It runs off a 48V 17Ah sealed lithium ion battery pack (assume it's 4x12V inside but I don't actually know) with a standard 3-pronged female plug receptacle like a computer monitor.
The charging adapters I have are 1.7A. I'd like to have a faster-charging adapter to carry with me for when I run out of range on the road, so i can do a full top-up in 2.5h rather than 5h. I'm figuring that 3A (which is less than 20% of 17A, which I learned as a rule of thumb) is safe.
It's easy to find a 3A adapter (I guess wheelchairs use them) but they all either say they're for sealed lead acid (SLA) batteries, or they don't specify.
I understand that the charging algorithms (whatever exactly that means) are different for SLA and Li ion. Can I safely substitute one of these adapters?
This is not a critical question. I don't use the scooter a lot. But I'd prefer not to destroy the battery pack or set the battery on fire by using the wrong adapter.
