Review & teardown: PowMr boost 10A solar charge controller for Electric Bike

Full review and teardown of a PowerMr boost solar charge controller. It can charge any Li-ion batteries up to 84 Volts. My intention is to use it for my E-bike. How good is it? Let's find out!

Great video! This info is very Helpful to those who are looking for these specific explanations,
and it's also FUN to watch - to those with inquiring minds! *I don't use any of this stuff, but still watched!
Nice Job!

13:49 I suppose that you could inline a little on/off toggle switch to kill the charge on the charge wire
and/or power on the power wire.. But the features this has seems good enough.

1 question.. With the battery plugged into the unit w/ no power coming in to the unit..
I wonder if there could be a slight parasitic draw? *I've noticed that on a lot of gadgets I've tested in the past.

Nice in depth review. The functions and capabilities of this unit are quite good but it's a bit rich that you need to open the unit to correct a production problem. PowerMr has a habit of doing this to its customers, I don't know how they are still in business. May be their customers are tech-savie like yourself who can diagnose and fix the problems?

As usual good information on your videos.Question where can I buy this solar controller? Thank you

Are you sure the 10A means output? It could mean 10A max input. At least it means that way on for example the genasun boost I use.

mine does not charge. it said 0.0 amp charge. while the volt meter connected from solar to the booster said 40 watts. weird.

I went looking on Amazon for it but this model never showed up. What brand and where did you get it?

Charging current is not the how much it charge the battery, it’s actually solar panel max current…! User manual is made really bad.
