I am looking for a smartcharger

Postby Kevin91 » 22 Jul 2020, 11:52am

Hello, I have the 36V Powerbank 400 battery with 11Ah. I need a charger with 2A charging current. My current one has 4A. In the long run it will be too much for me. Can someone recommend a replacement charger?

Are you talking about a Bosch powerpack 400 battery or something else? In what way is your current charger too much?

Hi I have a Bosch battery.
I am looking for a charger with a lower current, as I have read in a study that the battery life is extended if you charge it with a lower current.

You need the compact charger:

I don't think you'll get a non-Bosch charger to work, there is handshaking between charger and battery.

Overfast charging certainly reduces battery life; how fast you can get away with depends on the exact cells in the battery.
I suspect that the 4a standard charger won't significantly reduce battery life (guess not fact).

You'd hope that with the exorbitant prices they charge that the standard charger would have a switch for slower charging.

ebay completed listings show it going at £65 to £75 used.

My wife found this new smart charger from the internet. Anyone here who has bought or used it? Can you share your experience with me?

See thread on Pedalecs https://www.pedelecs.co.uk/forum/thread ... ost-567710
There are plenty of cheaper multi-rate chargers, there may be features of this one that make it worth it for you.

It almost certainly can't charge a Bosch battery.

You may find a power controller that you can plug your charger in to reduce the power output. There were thyristor controllers for controlling the speed of motors or dimming lights years ago. Ive got a home made one from an electronics kit which gives me a variable speed on my electric drill Heres something that may be similar on flebay but you would need to do more research. https://www.ebay.co.uk/i/274343255407?c ... gIag_D_BwE

You probably don't need one that powerful. A plug in light dimmer may be a better solution. Cheap too at about £5
At the last count:- Peugeot 531 pro, Dawes Discovery Tandem, Dawes Kingpin, Raleigh 20, Falcon K2 MTB dropped bar tourer, Longstaff trike conversion on a Falcon corsa. :D

It's not a smart charger in the way that those in the know can relate to.
It might be able to charge to a set voltage but it can't balance individual cell voltages or read them unless a matched bms with BT comm's is also used. An unbalanced battery using this device creates more issues then it solves.

I saw a competition on Facebook about this. To participate, you just have to like, share and explain why you want the LiON.
Finally, mark two friends to be able to participate. Maybe I'll be the lucky winner. Can then test it for free.
