Betso SB Charger Smart Battery Charger and USB PD Source

Ultra-compact, the Betso SB Charger charges 14.4 V 2054-style smart batteries and also works as a 100 W USB PD power source.

It charges at up to 4 A (65 W), taking a battery from 30% to 90% in under an hour and from 5% to full in under two hours. The charging current is set from 1 to 4 A in 1 A steps: 4 A when time is short, 1 or 2 A overnight to go easier on the battery. The charger never exceeds the safe limit the battery’s maker sets, and it detects and recovers deeply discharged batteries.

Its USB-C port also works the other way. With a battery inserted, the SB Charger becomes a USB PD source of up to 100 W, at 5, 9, 12, 15, or 20 V. It can feed a power distributor with a USB-C input or charge other gear.

A sunlight-readable OLED display under Gorilla Glass shows the charging state, the set current, the time to full or empty, and the battery’s voltage, temperature, and cycle count. Two RGB LEDs show power and charge status. The charger watches the battery’s temperature as it works, and its fanless, CNC-milled aluminum body runs silent.

It runs from the YDS-PD065A power adapter or any USB-C adapter, from 9 to 18 V DC with the SBCC-XLR cable, or from a vehicle’s 12 V outlet with the SBCC-CAR cable. Set in a DS-2S or DS-4S docking station, several SB Chargers become one multichannel charger.
