Ultra Power UP-PD2 30W 1-4S USB-C Multi-Chemistry Charger

The Ultra Power UP-PD2 is a compact smart balance charger for 1-4S LiPo and LiHV packs that runs from a USB-C source or a 9-20 V DC supply, which keeps it useful away from a mains socket. Its channels charge independently at up to 30 W and 2 A each, a good match for whoop, toothpick and 3-4 inch quad batteries.

Key features

• Adjustable current: 0.1-2.0 A per channel, so small 1S packs and larger 4S packs can both be charged at a sensible rate.

• Balance charging: 200 mA balancing keeps cells level as the pack fills.

• Colour IPS display: shows real-time voltage, current, capacity and temperature for each channel.

• Protection: over-voltage, over-current, reverse-polarity and under-voltage cut-outs, plus a built-in cooling fan.

• Other chemistries: also charges NiMH, NiCd and lead-acid (Pb) batteries.

On a full 4S pack (16.8 V) the 30 W limit holds charge current to about 1.8 A, which is 1C for an 1800 mAh battery. For 6S packs or faster charging of 5-inch batteries, choose a 100 W-class charger instead. Use a power source that can supply the combined wattage of every channel you run at once.
