This is a SKYRC E455 50W 4A Multi Chemistry Charger.

As the successor to the e450, this compact and handy charger offers more convenience. Because instead of an imprecise switch to select the charging current, this can now be selected simply by pressing a button. The integrated balancer adjusts the charge current for each individual cell individually to charge the LiPo battery to 100%.
The selection and the charge status of each individual cell itself are displayed via the LEDs. So you really always keep the overview. And with the included XT60 connector, you also get the assurance of always having the most common battery types connected correctly.

1. Compact, easy-to-use charger
