I deal with DC system quite a lot.
Very familiar with lead acid and AGM batteries charging and discharging characteristic, be it for boats house bank or for remote area use where in remote area , the generator run only 12 hours a day and the other 12 hours on batteries>>inverter for vital communication gear.
I never measure Gopro the way I measure other remote installation and I am new to lit-ion battery. I hate small connectors...
I know my dive light uses Panasonic protected 18650 battery. I have no idea that a GP battery internally has that circuit board
...great info Brite, many thanks.
One thing for sure, batteries best not to be charged more than 50% of its rated capacity. Its a common rule. The internal chemistry doesn't like fast charging.
I don't know how Lit-Ion is rated for its MilliAmp Hours but for deep cycle lead acid or AGM batteries this is a very important factor. I have not bothered to read much of Lit-Ion as its is still too expensive compared to lead acid and AGM which can take more abuse, for my work.
A C20 car battery ( cranking battery ) if rated at 100 amps hour is because 20 hours discharge ( hence C20 ), if we use it at C8, its probably become a 75 Amps hour battery or so, assuming we ignore the C8 application should be better served with deep cycle or traction battery. I am wondering how is Lit-Ion capacity is being calculated, what C rating actually ? For cameras and high power diving torch, the Lit-Ion is being sucked at C1 to C2 ...incredible.
I also do not know if Lit-Ion is best served with smart 3 stage charger like used for lead acid/AGM. The final 15% to 10% acceptance charge is so true and not many people knows this. Again I do not know if Lit-ion will suffer same fate as lead acid plate sulfation if the 100% true complete charging can't be practiced. In remote installation using lead acid and AGM, this last 10-15% is the pain in the a$$ in terms of time wasted compared to bulk charging and generator running time.
I never had the chance much to read on intelligent charging of Lit-Ion battery, compared to available smart ones for lead acid/AGM.
Brite, any tips for me ? I will Google it for sure but you probably can teach me more and faster....
