Not Lithium Polymer, looking at Lithium Iron. The LiPb batteries are fussy also, though not as much as LiPo. Also in most applications a LiPo would be cycled a lot ( notebooks - RC toys - cell phones ), whereas I am considering the main purpose to be a reserve battery that hopefully will not be used regularly.
The LiPb will work OK with a normal boat charger, but for best life there is a custom charger. http://shoraipower.com/chargers-c43 I think in "store" mode it keeps the battery at a specific partially charged point.

Must use a special charger which does a controlled discharge and then equalizes the cells - and you cannot discharge them beyond a certain point - they die.

I have a Costco group 31 deep cycle that I use for house and starting the Atomic 4. In reserve is a group 24 AGM that is intended to only be used to start the engine if the house battery dies or in an emergency to get home. I have considered saving some weight by making the AGM the house battery and keeping a LiPB battery as the backup. http://shoraipower.com/lfx36l3-bs12-p130 550 cranking amps, 36 amp hour equivalent, very slow self discharge rate and only 5 lbs. With the racing requirements of sealed batteries for any new units ( older ones are grandfathered ) I will be into a Gel or AGM at a minimum. For my use a single 70 AH house is all I need, and a suitable reserve for safety does need to be another 80 lb AGM. Also, in light use the LiPb may last a long time.
