LiPo Amigo (LiPo/LiIon Battery Charger) Pro

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.

(batteries are sold separately).
