Rather than burning off excess voltage/imbalance as heat like conventional balancers, acrive balancers shunt power between cells of a battery so seem more efficient, as well as having higher balance currents.
Julian, instead of having 4 separate amp meters, why not just use a selector? You can use a simple 4-point rotary switch- analog. You can even set it up to handle both meters with one switch.
It doesn't matter. It simply redistributes the charge until all cells are at the same voltage. I think it's meant to enter a low power state when the pack voltage gets low, but I can't see how that's implemented. The touch switch thingy is useless though - it keeps switching itself off - best to fit the touch disable link.
I'm sure I'd much prefer an ammeter that sensed the positive rail rather than the negative rail - with ones like these, the shunt is in series with the power supply zero Volts/ground and the load, adding extra impedance in the load ground. Has anyone come across such a module?
Yea a post bag 🙂
woof
@@TheEmbeddedHobbyist SQUEAK to both of ya and Julian !!
I hear and I obey. The like button has been pressed - several times.
Yay welcome back Julian I love your channel, we both share the same interest hehe :)
Thank you :)
Wooooooo Postbag
I purchased exactly the same boost modules, same issue, marking on the rear was meaningless.
The boost converters are so good ive used them only need more
Love your talks on products. Can not wait till you do a video on that active balancer never understood what they do and are if they necessary?

a bag of post indeed.
Bags of post :)
@@JulianIlett but it could have all been in one postperson's bag. 🙂
5:43 The number of digits has got nothing to do with accuracy
Julian, what is the burden voltage of the ammeter please? i.e. When 1.0 Amps is running through it what is the voltage across it?
A video with only post items should be called Post Alone.
the official gnuwn store does not send his artikel to germany.
Postbag!
Julian how does that balancer know which battery technology it is connected to? Could that be the link near the connector?

Mummmm ... Boost converters .... yummy
can you make a video of your shelves and shelves of boards and meters and just general stuff you end up not using
I have thought about that. I'm having a clear out - I might come across some interesting items :)

ACS712 and similar hall effect devices can be put anywhere in the circuit, and have galvanic isolation.
@@JulianIlett Oh, that sounds good! Thanks.
@@JulianIlett Do you know of any ammeters that use this (or similar) Hall-effect sensor with a built-in (panel-mounting) display?
Vocoder?
Vocoder hush
Lack of space :(
