cherche prise pour se brancher sur la batterie neato D85

Messagepar narmo » Mer 17 Mai 2017 15:52

Salut à tous,

je cherche une prise mâle si je ne dis pas de bêtise que je puisse brancher sur la batterie de mon netao D85 car cette dernière à du mal à durer aussi longtemps qu'avant et comme j'ai un chargeur pour batterie de modélisme, je voudrais lui faire faire quelques cycles de charge décharge.

Pour ensuite brancher pour la charge, je dois utiliser quels fils e a batterie, le noir et rouge?

Merci d'avance pour votre aide.

Merci pour ton aide!
Par contre ce que je cherche c'est la prise mais en femelle comme celle qui est sur le robot et je n'arrive pas à trouver cela sur des sites français car ceux que tu me proposes font des envois à l'internationale mais le prix est très très élevé!

Sur alix express est ce que je peux trouver ou ebay car je ne trouve rien?

Alors après encore des recherches j'ai peut être trouvé cela :
http://www.ebay.fr/itm/PCB-Header-Conne ... 1950788720

J'en prendrai un grand pour avoir plus de 6 fils!

Par contre est ce que tu es sûr que c'est bien du 3 mm car quand je mesure avec un pied à coulisse je trouve 2.54 mm par broche?

The Digi-Key reference shows related parts. The shell and the pins are separate. The Botvac has female pins in the battery side connector shell (same on XV with Molex connector).
Digi-Key shows the mfg part numbers for all the related pieces; see bottom of the catalog page for links to other parts. Look for these on other sources using the mfg part numbers.
The connector inside the Botvac has male pins.
It is common for the parts used in products to be industrial supplies not available retail except at distributors such as Digi-Key. For large wholesale orders the shipping from the U.S. is not important. Many different connectors are made in many sizes so only some of them may appear at Ebay etc.

I do not understand what you are trying to make.

Use the pitch on the part at Digi-Key, as specified by the mfg. The mfg data sheet may be shown there, a link. My measure may be only approximate. Digi-Key will show all the different connectors and their measures, in the extensive online catalog for engineers. This part has been successfully used in Botvac repairs.

Database Octoparts.com shows all industrial distributors of many electronic parts, at least IC's. Check for connectors.

To connect something other than the Botvac to the battery, the wires can be spliced into additional lines to some other connector in addition to the Botvac connector.
Temporary connections can be made inserting hook up wire into the battery connector female pins. Wrap with tape.

The circuit board header connectors shown can be used to make connectors for projects. Use thin heat shrink tubing over the soldering of wires to the PCB pins. These headers male and female are widely available on ebay etc. 0.1 in. spacing standard. Same as solderless breadboard, perfboard for prototyping.
Many other types of connectors are available on ebay. Many are used in RC models and other electronic appliances.

Digi-Key "expanded description"
6 Position Rectangular Housing Connector Receptacle Black 0.118" (3.00mm)


i.e., Shell, housing only; pins separate, different types.

Mfg Data Sheet drawing http://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=1445022&DocType=Customer+Drawing&DocLang=English

The Botvac inside connector (using male pins, separate) https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/1445049-6/A30240-ND/684963

Male pins https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/1-794608-1/A100902CT-ND/2259571
Female pins https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/794606-1/A30305CT-ND/5891961

The tool for extracting pins is too expensive. Use a drill to remove wires, destroy old connector.

Some Botvac users damage the battery connector by failing to release the locking tab pulling it out, pulling out wires.

Header connector at ebay referenced: headers have thick square connecting pins which may not fit into the female Mate-N-Lock pins or could stretch them wider, not good for the standard connection on the AMP male pins inside the Botvac. Try them on a separate AMP female pin before using in the shell.
Note the battery connector must support 4 amps current so a proper fitting pin is required, otherwise excess heating may occur. Charger 2 amps but the running Botvac can go higher, as when climbing obstacles. The battery is a high drain type.

For an external charger, one method is use a connector of the kind which is on the charger, and splice wires into the battery wires. A thermistor connection is needed on the charger. What type of charger do you have? It must be for a 12v NiMh battery system. I used external chargers on the higher voltage XV batteries.
There can be an issue that the Neato thermistors are not the same as used by the charger; there are many different types with different resistance. You must monitor the charging process to insure it terminates properly, following the battery terminal voltage; the battery will heat up around 14-15v, you can feel it get warm. The charger must terminate or the battery will be damaged, over heated. Separate thermistors can be supplied with the charger, which you place in the battery pack yourself, in addition to the included thermistors. Good contact with the cells is needed for proper temperature reading. Compare resistance of the charger thermistors with the Neato thermistors using an ohm meter, check compatibility.

NiMh batteries are damaged by self-discharge in long shelf storage, shelf-life problem. Some will recover with a few runs of the Botvac, on its own charger. Others are irrevocably damaged and do not recover. Short run time is the symptom of defective batteries.
