Do you know that person who never charges a battery without sitting right there, watching it? Neither do we.
E-bike and power tool batteries charge for hours, often overnight, when no one is around. The weekend is coming and the batteries need to be full next week? The instructions are clear. Even clearer is that no one follows them.
When safety and convenience compete, convenience usually wins.
We can’t prevent battery fires, or predict when they will happen, but we can stop them easily and reliably.
