Batterie Lithium\u00ae<\/sup> Lithium Ion battery 12V-40Ah<\/strong> - LiFePO4<\/h1>\r\n

La batterie PowerBrick 12V-40Ah<\/strong> LiFePO4 (Lithium Ferro Phosphate) a \u00e9t\u00e9 con\u00e7ue gr\u00e2ce au savoir faire de la soci\u00e9t\u00e9 PowerTech Systems<\/a>, entreprise Francaise sp\u00e9cialis\u00e9e dans la conception de batteries Lithium-ion hautes performances.<\/p>\r\n\r\n

S\u00e9curit\u00e9<\/h3>\r\n

Cette batterie LiFePO4 12V-40Ah<\/strong> offre une grande s\u00e9curit\u00e9 par l'utilisation de cellules cylindriques en technologie Lithium Fer Phosphate (LiFePO4). En effet, elle int\u00e8gre un syst\u00e8me innovant de contr\u00f4le (BMS, Battery Management System<\/strong><\/a>). ce syst\u00e8me assure un tr\u00e8s haut niveau de s\u00e9curit\u00e9 \u00e0 l'utilisation. Le BMS contr\u00f4le et \u00e9quilibre constamment les cellules de la batterie. Il met en s\u00e9curit\u00e9 la batterie en cas de mauvaise utilisation afin de la prot\u00e9ger et d'augmenter sa dur\u00e9e de vie.<\/p>\r\n

La batterie Lithium PowerBrick 12V-40Ah<\/strong> est prot\u00e9g\u00e9e par un boitier ABS \u00e9tanche<\/strong> qui r\u00e9siste aux projections d'eau et \u00e0 la poussi\u00e8re (IP55<\/strong><\/a> ) pour le mod\u00e8le STANDARD ou IP65<\/strong><\/a> pour la version PowerBrick PRO.<\/p>\r\n\r\n

Remplacement direct des batteries au plomb<\/h3>\r\n

La gamme de produits PowerBrick\u00ae a \u00e9t\u00e9 con\u00e7ue pour remplacer les batteries au plomb. Elle offre une densit\u00e9 \u00e9nerg\u00e9tique \u00e9lev\u00e9e, tout en restant l\u00e9g\u00e8re et peu encombrante.
\r\nLes param\u00e8tres \u00e9lectriques du powerBrick 12V-40Ah<\/strong> sont compatibles en tous points avec ceux d'une batterie plomb AGM de 12V<\/strong> . Dans la tr\u00e8s grande majorit\u00e9 des cas, le syst\u00e8me de charge peut \u00eatre conserv\u00e9 et aucun accessoire compl\u00e9mentaire n'est n\u00e9cessaire.\r\n<\/p>\r\n

Attention : <\/strong>Cette batterie est une batterie de traction ou de servitude con\u00e7ue pour d\u00e9livrer des hauts niveaux de courants. Elle n'est peut \u00eatre pas adapt\u00e9e pour le d\u00e9marrage de moteur thermique.<\/strong>
\r\nSi n\u00e9anmoins vous devez d\u00e9marrer un moteur thermique, v\u00e9rifiez que le niveau de courant du d\u00e9marreur est compatible avec le courant maximal que peut d\u00e9livrer la batterie.
\r\nSi vous recherchez une batterie d\u00e9di\u00e9e au d\u00e9marrage de moteur, veuillez consulter la gamme de produit PowerStart<\/strong><\/a> d\u00e9di\u00e9e \u00e0 cet usage.\r\n<\/p>\t\r\n\r\n

Assemblage facile et modulaire<\/h3>\r\n

Chaque batterie Lithium 12V-40Ah<\/strong> a une tension nominale de 12.8V.<\/strong>Elles peuvent \u00eatre assembl\u00e9es en s\u00e9rie (jusqu'\u00e0 4 batteries en s\u00e9rie) et en parall\u00e8le (jusqu'\u00e0 16 batteries pour la version PRO).<\/a>
De part sa technologie, la batterie PowerBrick\u00ae 12V-40Ah<\/strong> peut s\u2019installer dans tous les sens (verticalement, couch\u00e9e sur le flanc ou la t\u00eate en bas).
\r\n\tLa tension de l\u2019assemblage final peut donc varier de 12V<\/strong>\u00a0\u00e0 48V<\/strong> (pour 4 \u00e9l\u00e9ments en s\u00e9rie). Cela correspond a la quasi totalit\u00e9 des applications pour la le stockage d'\u00e9nergie, solaire ou \u00e9olien, la traction de v\u00e9hicules, les batteries de servictude, la robotique, l'industrie, etc.
\r\nDans le cas d'applications sup\u00e9rieures \u00e0 75VDC, l'utilisateur doit faire appel \u00e0 du personnel habilit\u00e9 basse tension (BTA)<\/strong><\/a><\/p>\r\n

La batterie Lithium PowerBrick 12V-40Ah<\/strong> est id\u00e9ale pour les camping-cars, les applications marines ou de plaisance<\/a> , la robotique, la traction \u00e9lectrique, le stockage d'\u00e9nergie solaire et \u00e9olien, l'industrie, etc.<\/p>\r\n\r\n

Batteries \u00e0 faible empreinte \u00e9cologique<\/h3>\r\n

Cette batterie LiFePO4 12V-40Ah<\/strong> a \u00e9t\u00e9 con\u00e7ue pour remplacer directement les batteries Plomb acide ou AGM d'ancienne g\u00e9n\u00e9ration. Ces derni\u00e8res sont peu performantes et n\u00e9fastes pour l'environnement par l'utilisation de m\u00e9taux lourds et d'\u00e9lectrolyte acide.<\/p>\r\n\r\n
