Hey goes guys... time to test the water...

First considerations on a battery charger?

The boat electrics are well set-up for extended anchoring independent of shore power. There is little need for engine charging and when it is required maximum benefit is gained through the smart charger and high output alternator. Equipment includes:
•Link 2000 battery monitor system
•separate heavy duty engine battery (1 YO)
•four Trojan T-105 6volt 235a/hr house batteries (4YO).
•Balmar 100amp alternator
•Alpha smart charge alternator regulator
•two Kyocera 136watt solar panels
•Mark PV Solar regulator
•Excelsior 1100 watt (3000 watt surge) inverter
•RCD protected 240volt power points (x4) and 2 shore cables with three plug solutions to meet most international needs
•electric and engine heated hot water cylinder (copper with stainless outer).

Short of solar and the engine, there are no provisions for battery charging whilst at berth for extended periods of time. I plan to utilise the deiso heater which pulls a fair bit of DC current apparently and would not lend itself to long-term at berth.

Ant suggestions on hooking up a mains charger to the battery bank?

Notably I think I (really a leccy) would be required to extend the 240 system closer to the batt for starters. With all the other equipment as above is it a job outside the scope of a DIY person or would the instruction manual cover the likes?

Thoughts? Good links?

Cheers...
