Until they get more main stream and cheaper, I'm good with the current types. Will probably buy another set of 6's when the old ones die.
I don't get the "special handling" excuse or they are too complicated to charge. They are easier to take care of than a lead acid battery.
To properly care for a lead acid battery:
Add in temperature compensation
Occasional equalization charge
Don't discharge less than 50%
Each manufacturer has specific charge voltages to get the most out of the battery.
Oh, and don't forget to top up the electrolyte
They are hard to overcharge but you can boil away the electrolyte.
Watch out for the self discharge rate while in storage.
Keep them ventilated... not in your trailer.
If it comes with a good BMS (battery management system) you can't over charge or discharge the battery.
Charge at specified voltage and ramp down the current until full.
Charge or discharge to 50% capacity if it is going to be stored for a while.
Most good programmable chargers will be able to handle lithium batteries, if you program them properly, but I would expect as soon as they become popular chargers, converters, and solar controllers will come out with lithium specific profiles
Do you find taking care of your cell phone battery more difficult than your rv battery or car battery? (Not directed at anyone, just making a point)
I do agree that cost is still prohibitive and my lead acid batteries work just fine for now but lithium is or will be a great alternative.
