I saw on this picture that we should find a 29.V battery type 7S; it means 7x 4.2V units and with how many Ah ? Thanks.

I have enough place for a 25.2V 6S 4000mAh, will it work ?
I am not sure this battery is OK.
You need a battery with only two wire for charging and use .
I use this one
with this BMS:
and charger from marotronics.
 
OK, wow... I didn't planed such a monster; well.... the BMS is a good thing... now the question, where I will put all this thing in... .
 
I understood... this big battery is 3 x 7S/3,5Ah that are parallel connected => 3 x 3.5Ah = 10.5 Ah; it means, the BMS will control on each point, a group of 3 batteries and not one. I think about a 2x7S/3.5Ah =>7 Ah. it means a 7S2P instead your 7S3P.

I just found on amazon that the Matrix Mow 800 originaly, had a 4,4Ah battery. If I use a 7Ah battery, it will be quiet better than those 4,4Ah. To have the possibility to use the original battery box, maybe I will have to put the BMS out of the battery pack..... .
 
That is the original Batterie with bms

I saw those batteries, but I need only 2 connections that are in the same time for charging and for the Power PCB, it means, I have to change things on this batterie. Also, no garantie about the origine of batterie elements. Thisone from Fa akkuservice-dellinger sollt deutsches Qualität sein :) made in China but build in Germany.... Also 7Ah ggn 6Ah :D
 
Sascha did you only used the charger supply, and dismantled the original Charger PCB from the station ? Thanks.
 
Yes, i have removed the PCB from the Station and put the Ardumower Sender in it.
I want to used the LED's in the Station in a next Version with Bernards Wifi Station Sender.
 
Thanks Sascha, I'm on building Bernards Wifi Station Sender.
I have all the electronic parts; I have to order more PETG for the printer, but before installing it in the "box", I will test it.
 
Check that you have the correct INA3221.
Need to have common GND on the 3 channels.
I have connections between all 3 GND needed plots Bernard, thanks.

Well, I already need those resistors for perimeter wire but I don't know the correct value for now to obtain 1A Max on the loop.
