Hi,
I got a handheld vacuum cleaner and its runtime is quite bad with the included batteries. So I was thinking, hey this will be easy, I can surely come up with something to upgrade it. But I found one problem.
My initial plan was to replace 4.8V NiCd with an 18650 batterypack (1S, 2S) and than either boost or buck it to the desired voltage. The problem is that the vacuum cleaner is running at 10 Amps so none of my small boost converters (rated for 2A) will do. I can get a larger boost converter, but thats kinda useless due to its size. I checked the motor and it is rated for 4.6V.
So is there an another good solution to get 4.6V from lithium batteries which would be able to handle at least 10A?
Thanks a lot!
