CarlS,
What would be the most suitable battery type for those like me diving mostly in 3rd world remote areas where power supplies spike and are intermittent? Ive heard that lead acid has an advantage in these conditions.... any truth to that or recommendations?
Thanks,
A Chanster
Hi, My suggestion would be Nickle Metal Hydride(NiMH). These cells have a much higher power capacity to weight and size than SLA batteries. It is true that Lithium Ion has a even higher capacity than NiMH, Lithium Ion are more delicate when it come to charging and can be damaged more easily, physically and electrically. You can also very easily setup a solar charger for your battery pack with inexpensive flexible solar panels from catalog stores like Northern Hydraulics. Solar cells give a low current output, which is the best way to charge NiMH batteries to get full capacity and a long life.
Please let me know if you have any other questions.
Best Regards, Carl
