FF Battery question (ryobi Lithium Ion?)

[Harry Hill]

There are big differences in Lithium technology. While Lithium Polymer will charge to 4.7 volts per cell and discharge at a more even rate Lithium Ion charges to 3.3 volts per cell and hold a steady level longer but will fall off rapidly without warning. LiPo drops evenly but cannot be allowed to fall below 3 volts per cell or will be ruined and cannot be recharged. Both take a dedicated charger. Both can be partially discharged and recharged without damaging them and will take over 1000 charge cycles. LiPo is highly volatile and if damaged will burn with a white hot fire, not a good thing on a boat. Probably the type of battery that was on the dive boat. I use LiPo because that is what I own but if I buy another battery for my kayak it will be LiIon.
