Battery Energy Estimator 300
Better Embedded Engineering
Mfr. Part #
BEE 300
Product Description

The Battery Energy Estimator 300 (BEE 300) is a battery life estimation meter which is a key tool for every IoT engineering team. When developing a battery powered device it is necessary to measure the current consumption in order to estimate the battery life - the BEE 300 is the ideal low-cost tool to accomplish this. It provides clean power to the device under test and continually monitors the current consumption.

Additionally, The BEE 300 incorporates a microprocessor that rapidly takes samples of the current signal and accumulates these values that represent the energy drained from batteries along with the elapsed time. With this data, the BEE 300 system then calculates the estimated life the device can operate on the defined batteries. The BEE 300’s ease of use will have you up and running in just minutes!

Why GroupGet?

As with any hardware product, minimum order quantities are required to achieve a reasonable cost point. This project will provide the seed funds to make minimum orders to the factory to keep the manufacturing costs low. We would also like to use this opportunity to gain field exposure and user feedback.

How it works

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds. Please see our FAQ page for more details on our billing process.
