In the video, the narrator investigates whether it's better to DIY or buy a solar battery charger for LiPo/Li-ion batteries. The narrator emphasizes the need for the charger to adapt to constantly changing solar radiations and also the need for it to have capabilities to easily connect to projects as a power source. After thorough testing, a commercial option was found to be satisfactory, but it was lacking some important features such as sufficient battery protection, no boost converter for stable 5V output and absence of MPPT functionality.
Furthermore, the narrator constructed his own DIY solution using an IC called CN3791 from Consonance Electronics. The narrator praises the DIY option for its versatility, added protection features and higher efficiency, despite the lower cost-effectiveness and time-intensive assembly. It's a clear and in-depth review that gives viewers an idea of how solar battery chargers work and what they should look for when sourcing or making one. Based on the video, the DIY option proves to be the winner.
