Ultra Power UP100AC Plus 100W 10A 1-6S Multi-Chemistry Charger

The Ultra Power UP100AC Plus is a single-channel 100 W balance charger with a built-in mains power supply, so it runs straight from a wall socket or from a DC source. Up to 10 A of charge current covers everything from 1S whoop packs to 6S batteries for 5-inch freestyle and long-range quads.

Key features

• Wide chemistry support: LiPo, LiHV, LiFe and Li-ion packs from 1S to 6S, NiMH/NiCd from 1 to 15 cells, plus lead-acid (Pb) batteries.
• Balancing and storage: individual cell balancing during charge and discharge, and a storage mode for packs that will sit unused.
• Adjustable terminal voltage: set the lithium full-charge voltage between 4.18 and 4.30 V per cell; delta-peak sensitivity is adjustable for NiMH/NiCd.
• Battery meter and memory: built-in pack and cell voltage checker, and 10 stored charge profiles.
• USB port: PC control and firmware upgrades.

Specifications

The 100 W ceiling sets the real charge current on bigger packs: a full 6S pack (25.2 V) charges at about 4 A, which is 1C for a 4000 mAh battery, while 4S packs (16.8 V) can take nearly 6 A. If you charge several 6S packs per session, a higher-power dual-channel charger will save time.
