Cependant, leur sortie de c\u00e2bles ne correspond pas toujours au porte-accu fourni dans le kit des camions Tamiya Europ\u00e9en (le porte-accu qui se place sous le ch\u00e2ssis). En effet, les accus Lipo ont une paire de c\u00e2ble de forte section pour le branchement de l&rsquo;accu au variateur, et un cordon de fils plus fins pour la prise d&rsquo;\u00e9quilibrage.

r\u00e8gles de s\u00e9curit\u00e9 pour les accus Lipo<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Pourquoi utiliser un accu Lipo ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">En comparaison d&rsquo;un accu Nimh, un accu Lipo pr\u00e9sente deux avantages:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1) Un accu Lipo ne s&rsquo;autod\u00e9charge que tr\u00e8s peu, contrairement \u00e0 un accu Nimh. Du fait d&rsquo;une chimie diff\u00e9rente, un accu Lipo ne perd pas de charge lorsque il est stock\u00e9. En fait, son autod\u00e9charge est tr\u00e8s faible, ce qui la rend n\u00e9gligeable. Comparativement, on consid\u00e8re qu&rsquo;un accu Nimh perd 10% de sa charge par mois. M\u00eame s&rsquo;il n&rsquo;est pas utilis\u00e9, un accu Nimh se d\u00e9charge donc de lui-m\u00eame.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2) Un accu Lipo fourni un courant instantan\u00e9 plus elev\u00e9 qu&rsquo;un accu Nimh. Un accu Lipo est capable de fournir un courant plus \u00e9lev\u00e9 sans faiblir (sans que sa tension ne chute). Sur un accu Nimh, si le courant demand\u00e9 est important, la tension va chuter et donc la puissance disponible va baisser aussi. Sur un tracteur simple, cela n&rsquo;a pas beaucoup d&rsquo;importance, si on tracte un faible poids. Mais lorsque&rsquo;on tracte un poids relativement elev\u00e9 (remorque benne, ou porte-engin) un accu fournissant la puissance n\u00e9cessaire est int\u00e9ressant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Par contre, un accu Lipo pr\u00e9sente un inconv\u00e9nient important: son utilisation doit \u00eatre faite de mani\u00e8re stricte. Un accu Lipo doit \u00eatre charg\u00e9 avec un chargeur adapt\u00e9, et dans le bon programme de charge, afin d&rsquo;\u00e9viter que la tension par \u00e9l\u00e9ment ne d\u00e9passe 4.20 volts. L&rsquo;accu doit \u00eatre charg\u00e9 avec son connecteur d&rsquo;\u00e9quilibrage connect\u00e9, afin que la tension de chaque \u00e9l\u00e9ments de l&rsquo;accu soit contr\u00f4l\u00e9e.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lors de la d\u00e9charge, la tension minimum de 3.3v par \u00e9l\u00e9ment doit \u00eatre respect\u00e9e.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Un accu Lipo mal charg\u00e9 ou trop d\u00e9charg\u00e9 va gonfler ( du fait de d\u00e9gagement gazeux de ses \u00e9l\u00e9ments chimiques qui se sont d\u00e9grad\u00e9s ) et il y a un risque d&rsquo;\u00e9clatement voire d&rsquo;incendie. C&rsquo;est ainsi qu&rsquo;il est pr\u00e9f\u00e9rable de les charger et de les stocker dans un <a title=\"Sac de charge Lipo\" href=\"https:\/\/www.tecnimodel.com\/accus-lipo\/3705-sac-de-charge-lipo.html\" target=\"_blank\" rel=\"alternate noopener\">sac anti feu<\/a>.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">&nbsp;<a href=\"https:\/\/tecnimodel.com\/blog\/trucs-et-astuces\/guide-d-utilisation-des-accus-lipo\/\" data-type=\"post\" data-id=\"30695\" target=\"_blank\" rel=\"noreferrer noopener\">Voir plus d&rsquo;infos sur les accus Lipo dans cet article.<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Contr\u00f4ler la d\u00e9charge de l&rsquo;accu Lipo.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Un accu Lipo ne doit en aucun cas \u00eatre d\u00e9charg\u00e9 de mani\u00e8re excessive. Ceci entra\u00eenerait sa destruction et des risques d&rsquo;incendie. La tension minimum d&rsquo;un \u00e9l\u00e9ment Lipo de doit pas \u00eatre inf\u00e9rieure \u00e0 3.3v (donc 6.6v au total pour un accu 2S). Il est donc n\u00e9cessaire que l&rsquo;\u00e9lectronique embarqu\u00e9e dans le mod\u00e8le permette de contr\u00f4ler cette tension et stoppe le moteur ou lance une alarme sonore lorsque l&rsquo;accu Lipo est d\u00e9charg\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Modules Tamiya MFC-01 ou MFC-03<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le porte-accu des camions rc Tamiya est pr\u00e9vu pour des accus Nimh 7.2v format stick.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Certains accus Lipo peuvent \u00eatre utilis\u00e9s mais une l\u00e9g\u00e8re modification tr\u00e8s simple du porte accu est n\u00e9cessaire.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pour ceux qui utilisent un module multifonctions Tamiya MFC-01 ou MFC-03, ces modules ne sont pas con\u00e7us pour contr\u00f4ler la d\u00e9charge d&rsquo;un accu Lipo. N\u00e9anmoins, ces modules fonctionnent parfaitement bien avec un accu Lipo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il faut donc ajouter dans le camion un petit module d&rsquo;alarme, connect\u00e9 \u00e0 l&rsquo;accu Lipo, et qui alertera lorsque l&rsquo;accu sera d\u00e9charg\u00e9.

Mais surtout, ce module est r\u00e9glable et va d\u00e9clencher un fort sifflement lorsque l&rsquo;accu sera d\u00e9charg\u00e9 et aura atteint la tension limite r\u00e9gl\u00e9e.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Variateurs Servonaut<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;Les utilisateurs de variateurs&nbsp;<a href=\"https:\/\/www.tecnimodel.com\/303-servonaut\" target=\"_blank\" rel=\"alternate noopener\">Servonaut <\/a>peuvent configurer leur variateur pour utiliser un accu Lipo (voir la notice livr\u00e9e avec le variateur). Ainsi, le variateur stoppera le moteur lorsque l&rsquo;accu sera d\u00e9charg\u00e9, ce qui \u00e9vitera de l&rsquo;endommager. Sur les variateurs S20 ou M20+, ce r\u00e9glage se fait par un petit cavalier. Sur le variateur S22, ce r\u00e9glage est automatique.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il est cependant conseill\u00e9 d&rsquo;utiliser aussi un module d&rsquo;alarme comme indiqu\u00e9 ci-dessus afin de contr\u00f4ler l&rsquo;accu Lipo \u00e9l\u00e9ment par \u00e9l\u00e9ment, pour \u00e9viter qu&rsquo;un \u00e9l\u00e9ment ne se d\u00e9charge de mani\u00e8re importante par rapport \u00e0 l&rsquo;autre. En effet, les variateurs qui contr\u00f4lent la tension de d\u00e9charge d&rsquo;un accu Lipo ne contr\u00f4lent que la tension totale et pas la tension \u00e9l\u00e9ment par \u00e9l\u00e9ment. Ce module d&rsquo;alarme est donc une s\u00e9curit\u00e9 additionnelle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Autres variateurs<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Il convient de v\u00e9rifier pour chaque mod\u00e8le de variateur s&rsquo;il int\u00e8gre une s\u00e9curit\u00e9 de d\u00e9charge d&rsquo;accu Lipo.
