A range of compact, convenient USB-C LiPo/LiIon battery chargers, perfect for feeding hungry batteries.
We've spent quite a lot of time at Pirate HQ over the last few weeks figuring out ways to charge up batteries for our Badger 2040s, and we've come up with all sorts of horrible solutions. Good news though - you won't have to make do with dubious bits of left over prototype, because we've made some straightforward, small LiPo battery chargers that are just the job.
LiPo Amigo Pro is a bit larger and has some additional tricks up its sleeves. It's got two JST-PH connectors so you can charge your battery and power your device at the same time (and switch seamlessly between USB and battery power). It also has a power on/off button and extra built in battery protection.

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- LiPo
- A LiPo (lithium polymer) battery is a rechargeable lithium battery widely used in portable projects because it is light and compact. LiPo cells need correct charging circuitry and careful handling to stay safe, so equipment that supports LiPo generally includes charging or protection hardware suited to that battery type.
- MCP73831
- A lithium battery charger chip used to safely charge a single-cell LiPo battery. It matters because it lets the board recharge a battery from USB or another input without needing a separate charger module.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
