    Works well with Heltech V3 meshtastic device

    Purchased the 1100mAh variant to use with Heltech V3 device. It works and charges well. Great value for the price.

    Soap dispenser rechargeablle

    Great product! And customized per my request. World class customer service.

    Quad copter battery

    Wouldn't work in my drone. I think the problem was on my end as I probably didn't order the correct battery. Unit would shut down when full throttle was tried. No fault of the batteries, I suspect. Will talk to Rokland when time permits

    Great for Lily go LoRa32 modules

    Plugs right in to the Lora32 boards and powers them up. 2000mah only slightly wider than the board itself so you can still package it up very compact and have long battery life. Now just need to come up with a 3d printable design to house it.
