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.
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
