Product description

Lithium batteries protect themselves: when the voltage drops too low, the built-in BMS switches the battery off and ordinary chargers can't see it. This charger detects that state, wakes the battery gently, then charges and maintains it.

Good for

  • Sport bikes with lithium batteries
  • Snowmobiles
  • Jet skis with LiFePO4 upgrades
  • Race and track cars
  • RV and camper house batteries
  • Lightweight starter batteries

Is it the right one?

Look at the battery's own label. If it says LiFePO4, lithium iron phosphate or lithium-ion, this is the right charger. AGM, GEL or flooded batteries need the Lead Acid Smart Charger.

How it works

Three steps in the fall. Nothing to do until spring.

  1. 1

    Connect it

    Attach the output lead to the battery: red to positive (+), black to negative (−).

  2. 2

    Plug in USB-C

    Use a USB-C PD or QC power source: a wall charger, a power bank or a vehicle USB-C port.

  3. 3

    Leave it

    It charges the battery to full, then switches to maintaining. Leave it connected until the season starts.

Running lead acid instead?

Keeps a stored 12V lead acid battery full all season, then hands it back ready to start. Clip it on, plug it into any USB-C charger, and walk away.

Questions before you buy

Can't find your answer? Ask us and a real person will reply.

Which charger do I need?

Check the label on the battery. AGM, GEL, SLA, flooded or "maintenance free" means lead acid. LiFePO4 or lithium means lithium. Both chargers are 12V only.

Can I leave it connected all season?

Yes. That's what it's for. Once the battery is full, the charger switches to maintaining and only tops it up as it drains.

What USB-C power source does it need?

Any USB-C charger or power bank that supports PD or QC fast charging. Most modern phone and laptop chargers do.

Will it work on a 6V or 24V battery?

No. Both chargers are made for 12V batteries only.

What vehicles is it for?

Anything with a 12V battery that sits for weeks or months: motorcycles, boats, jet skis, snowmobiles, ATVs, RVs, classic cars and lawn tractors.

Do you ship to Canada?

Yes. We ship across the United States and Canada.
