Hello Nick,
How long are you looking to float charge the cells? Our batteries have a very high shelf life (due to our very low self discharge rates). They will only self discharge about 1% / week. So they can be kept on a shelf through an entire season if need be.
Back to the question at hand. Yes they can be float charged. There is no designated amperage to set you will want to use whatever amperage is needed to maintain 3.6V / cell. A charger with a float setting that can be adjusted to 3.6V / cell should work nicely.
Please let me know if you have any other questions.
Brian
