EnBo PU technical details

Tech details

From the beginning, electric LEGO® models have been powered by AA or AAA batteries.
So far we have used alkaline or NiMh batteries, but each type has its drawbacks.

Available battery solutions for the Technic HUB

Alkaline Battery

Advantages:

  • can be cheap (if you don’t play much)
  • can have very strong ones
  • easily accessible
  • can be reused in other devices because it is widely used in electronics

Disadvantages:

  • not so cheap if you want quality and power
  • the output voltage drop may be significant under heavy load
  • non-rechargeable, disposal generates a lot of waste
  • capacity varies greatly depending on the price
  • It can’t stand really high currents

NiMh Rechargeable Battery

Advantages:

  • rechargeable many times
  • withstands high current demand
  • can have very strong ones
  • easily accessible
  • can be reused in other devices (if the lower output voltage is not a problem) because it is widely used in electronics

Disadvantages:

  • battery charger required (additional cost)
  • pretty expensive
  • lower output voltage (1.2 V) compared to the alkaline battery (1.5 V)
  • The output voltage drop may be significant under heavy load

Let’s see what we have to offer with the new EnBo PU battery

The current design addresses the following disadvantages:

  • fluctuation of the output voltage under high load and during ageing
  • easy recharging with commonly available solutions
  • large capacity
  • retain the original appearance

Technical Specification:

  • Stable 9V output up to full discharge
  • Easily handles 5A power demand
  • The included batteries are 2040mAh 18500 cells with a total capacity of 14.6Wh
  • USB-C charging port for 2A fast charge
  • Built-in battery protection for overcharge, over-discharge and overcurrent

To keep up the good progress I need financial resources so i just have to focus on the project I’m running. Here’s a link to my Patreon if you want to support me: Become a Patron!
