This makes the charger widely applicable for various brands of e-bikes &#038; fat bikes. <\/p>\n<p><strong>Fast charger 4 amps<\/strong><\/p>\n<p>The 4A (4 amps) designation indicates the charging current, or the speed at which the battery is charged. In practice, this means a 13Ah battery will take just over 3 hours to fully charge. <\/p>\n<p>Check beforehand if your battery is suitable for fast charging. Charging with a higher amperage can lead to extra wear and a shorter battery life if the battery is not suitable for it. <\/p>\n<p><strong>Reliable quality as originally supplied<\/strong><\/p>\n<p>This charger is produced by Sans, the OEM manufacturer that supplies chargers for various European e-bike brands. This means you are choosing a charger with the same technology and reliability as the chargers standardly supplied by bike brands with their batteries. <\/p>\n<p><strong>Why a 42V charger belongs with a 36V or 37V battery<\/strong><\/p>\n<p>Although the battery says 36V or 37V, an e-bike battery is charged to approximately 42V when fully charged. This is because the lithium cells in the battery are each charged to 4.2V: 10\u00d74.2=42. Therefore, 36V &#038; 37V batteries in this category use a 42V charger.  <\/p>\n<p><strong>Charging e-bike batteries &#038; extending lifespan<\/strong><\/p>\n<p>How you charge and use an e-bike battery has a major impact on performance and lifespan. By handling charging and storage smartly, you prevent unnecessary wear and get the most out of your battery. <\/p>\n<p>Read everything about e-bike battery charging and battery management <a href=\"https:\/\/rap-webshop.nl\/en\/use-and-management-of-the-li-ion-bicycle-battery\/\" target=\"_blank\" rel=\"noopener\">HERE<\/a>: Battery Management<\/p>\n<p><strong>Charger not working? How to identify the problem <\/strong><\/p>\n<p>Does your charger seem to have stopped working or is your battery not charging (properly)? In many cases, it&#8217;s not immediately clear whether the problem lies with the charger or the battery. Causes can range from a faulty connection (RCA plug) to a problem in the battery or a malfunction in the charger itself.  <\/p>\n<p>Not sure where the problem lies?
