AGM Adventures- Update

If there is no harm to the battery from getting that 55 instead of 27 amps, it is not an issue. If there is harm from that, then in theory I would have to use a 25 amp converter or else get a second battery to bank them so the 55 amps is shared 27.5 each.

Or I could not use the converter at all when on shore power for the weekend and just run the batts down till home again. Or I could use my 2 amp charger as the converter for when away. it would help a little bit after the power came back on, sort of.

I've been reading and re-reading this thread in it's entirety and think I now understand the issue of AGM battery charging temperature compensation - i.e. not overheating what is intended to be a normally sealed battery and not blowing out the vents from excessive pressure. Since I too am now planning on a single AGM to power my camper and on occasion power my 1000 watt inverter It seems I have all the more reason to be happy with my recently acquired CTEK Multi US 7002 charger ... with a maximum charge rate of 7 amps there's no way it's going to overheat the AGM regardless of ambient temperature, which in itself probably explains why this charger doesn't offer temperature compensation. The fact it will take much longer to fully recharge the battery is irrelevant to me as I'd be recharging once I get home instead of using a genset while still camping. BFL - you mentioned that one rep you spoke to also mentioned the CTEK, maybe it's a solution for you as well. FWIW, I haven't modified my trailer at all, just simply turned the crappy WFCO off and use the much more capable CTEK instead. :B
