BS Battery BK20 3-Bank Smart Battery Charger & Maintainer (Lead Acid & Lithium)

Regular price ¥37,700

If you've got a garage full of bikes, the BS Battery BK20 Smart Bank keeps three batteries charged and maintained at the same time from one wall-mounted unit. Each of its three channels works on its own, so you can have a 12V lithium battery, a 12V AGM battery and a 6V vintage battery all hooked up at once, and each one gets the right charge.

Every channel automatically detects lead-acid or lithium (LiFePO4) technology and uses an adaptive charging algorithm, so there's zero risk of overcharging. A Force mode can recondition a deeply discharged lead-acid battery or wake up a lithium battery that has gone "dead" after being run too low, which saves a lot of batteries that a standard charger would refuse to charge.

It's built for home garages, shops and dealership storage, and it can be wall mounted to keep cords off the floor.

Key Features

  • Three independent channels: charges and maintains 3 batteries of different voltages and technologies at once.
  • 2 amps per channel, 6V or 12V selectable.
  • Auto-detects lead-acid or lithium on each channel.
  • Zero overcharge: adaptive 10-stage charging for lead-acid and lithium (LiFePO4); lithium batteries get no float stage and charging stops when full.
  • Force mode: reconditions low-voltage "dead" lead-acid batteries or wakes up "dead" LiFePO4 batteries.
  • Safe: spark-free connection with reverse polarity, short circuit and internal overheat protection.
  • Easy to use: connect and forget.
