Building My Laptop Battery Power Bank
So about 3 months ago, I bought a new laptop. Asus GL502 (Republic of Gamers). I was not quite impressed with the battery life, BatteryInfoViewer Software shows it has lost about 15% of its battery health. Purchasing a new one was not an option, at least for now.
So I set out to building a Powerbank for the laptop, with the option charging phones when needed. So below are the pictures before, during and at the end of the work.
The initial plan was to build a 24v system, then using a dc to dc converter, step it down to 19.4v that my laptop would need. While waiting for the parts I ordered from china, I built the 24v battery pack (6S8P).
One arriving and during test, I discovered the 300w DC to DC converter was faulty in a way. It would only boost the voltage and not step down. So I change the plan, I do not have the luxury of starting dispute, initiating returns etc. I change the plan from a 24v system to a 12v system and boost the voltage from 12v to 19.4v. So my battery pack is now 3S16P, 12.6v.
Some drilling, grinding, soldering, etc works that had to be done. I still plan on reverting the system to 24v in the future, but for now, I will use it this way. Wow I'm currently making a laptop power bank this is a really helpful piece |
