David,
Find yourself a good electronics hobbyist who understands charging
circuits,
it should be a simple job to tweak the regulator voltage so it fully
charges
your LiFe battery, (provided the circuitry is not encapsulated or potted)
however if you do this then CLEARLY mark it as modified because it will
potentially kill SLA batteries after a short time, if you were in the UK I
would
offer to look at this for you, however posting it to and from the US is
impractical.
Ben.
