← Return to Browse Topics PageI wanted to share with you my wiring of a battery bank for the system I am working on. The system is one that was started some time ago by the homeowner/prepper. They got swindled by a man/huckster giving out false information about solar systems. The short story is this…the folks ended up with a…
“PWM” – Pulse Width Modulation is the most effective means to achieve constant voltage battery charging. PWM regulation tapers the voltage according to the battery’s condition and recharging needs. PWM has recently surfaced as the first significant advance in battery charging.
note: I started working on this article back in 2017 but due to the “crash” it got put on hold. I finished this article over the last couple of weeks. What I was looking for in a AA & AAA battery charger was two-fold, ability to charge AA & AAA batteries; 1) using 110vAC power…
note: article first appeared September 2015 I’ve never seen anything so conclusive in all my testing of gear. I mean it was crystal freaking clear what the outcome is. Here’s the short of it: So, the bottom line is…only use AAA batteries when you don’t have any other battery option available. What my testing showed…
Article first appeared August 2015 There are times, especially with electronics, that you want to use AA batteries but to do so would give you and “over voltage” situation that would burnout those sensitive electronics. Well, there is a solution…dummy batteries. Briefly, these are battery “look-a-likes” but are not actually batteries. They pass current through them but…
Article first appeared in June 2015 I am a huge Baofeng UV-5R handheld radio fan! Yes, it is a Ham Radio, but it is also much, much more and I love the little radio. It is a dynamo! The radio is a great size, packed full of features, reliable, and more than anything else EXTREMELY affordable.…
This article was first published in late 2017 and subsequently lost in the website crash. I was unable to retrieve it, I had to rebuild it from my notes and scattered bits and pieces. This article is the result. Comparison/Evaluation of Rechargeable AA Batteries – Eneloop vs. Tenergy Panasonic BK-3MCCA4BA Eneloop AA Tenergy Premium AA…
