Module battery management / charging with protections

Module battery discharge load manager with protections wondom

This ultra-complete module allows you to use 5x 26650 cells to power many types of electrical devices. It offers a considerable autonomy and large power while keepind a thin form-factor.

Built for a wide range of possibilities, the module is already equipped with an impressive array of connectivity for quick and easy integration.

The circuit controls the charging and discharging of accumulators with  safety regarding invidual overload / overdischarge of each cell.

Very versatile, the circuit is able to charge its cells from any DC power source between 5 and 24V which can provide at least 2 amps.

5 x 26650 Accumulators

Caution: batteries are not included

The module's cradle is intended to simultaneously receive 5 large capacity 26650 batteries. It is possible to use 5 x 5500mAh cell for a huge total capacity.

This configuration also achieves high voltages : the card will deliver 21V at full load.

The batteries must always be accumulators 3.7V lithium chemistry (4.2 full load).

Battery chemistries such as LiFePO4 (iron phosphate) are not suitable.

All traditional connectors in-circuit connection are already mounted. The connectors are already soldered and it only remains to choose the appropriate wiring to suit your needs.

input is found (charge) on a DC jack connector 5.5 / 2.1mm and a 4mm connector. The one and the other of these connectors arecompatible with all voltage ranges supported as input.

6 different connectors allow great native compatibility with most of the modules that may be connected altogether. Note that it is possible to simultaneously use multiples outputs to power many devices, provided that the overall load subjected to the battery module is less than 10A.

Danger accus : le produit n'est pas véritablement 5 à 24V - courant excessif
D'après la vidéo commerciale, Wondom a testé son chargeur sur des alims 5V, 12V, 19V et 24V qui sont des valeurs standard sur le marché. Ils en ont déduit que toute tension de 5 à 24V était acceptable. Erreur : le produit charge bien à environ 2A si vous utilisez une de ces 4 tensions.
Mais si vous êtes en dehors, ce produit va endommager vos accus ou devenir dangereux car le courant de 2A typique se met à augmenter dangereusementà partir de 12.5V pour dépasser 3,4 A à environ 14V. Au delà il recommence à baisser de 3.4A à 2A lorsqu'on passe de 14V à 19V.

Conclusion : ne surtout pas alimenter de produit de 12.5V à 18.5V car il ne régule plus du tout correctement le courant de charge des accus. Dommages aux accus assurés, voire risque de feu ?

C'est vraiment dommage car le produit est bien pensé à la base, l'universalité des connectiques, l'indicateur de charge, et ce look d'enfer en noir, mais certainement pas 5 à 24V

Ce produit doit être corrigé pour être 5 à 24V véritablement, ou alors il faut modifier sa fiche technique pour dire clairement de n'utiliser que 5V à12V et 19V à 24V, mais surtout pas la plage 12 à 19 V
