Nice, be pricey for shipping for me though.ewinters wrote:Well is a Brazilian eBay equivalent: (Fonte Modulo Eltek Flatpack2 Retificador 48v 3000w 56a
That's good to know. I need 88V from two series.ewinters wrote:I'll charge through an adaptto controller, so no mods required.
There appears to be some differences straight off and looks like several years difference in age, to the modded unit shown.ewinters wrote:I took some pictures from the inside so the people that can read chips may tell. Is all the same for me.

I did similar, but I insulated the metal casing with electrical tape first. Haven't used it yet, still waiting on the last few pieces for my build.ewinters wrote:My solution for the connectors, epoxy and insulating tape, a DIY classic. It is only touching the back panel, so it can be removed.
So can you put a different supply is series, say a 24V variable output bulk power supply and vary say from 20-30V, to give 57.5+(20-30) V 77.5 - 87.5V, charging 22 - 24S lifepo, or 19 - 21 lipo.ewinters wrote:I read somewhere here that you could connect in series with a charger, that way the amps will be limited by the charger (voltage will be increased though).
Sweet, Thanks.eTrike wrote:You will be limited by the current of the weakest supply.
Thanks for your reply. Is your grey Flatpack2 the HE version as in the photo posted above?dgh853 wrote:I have tried to set the default voltage on grey twin fan Flatpack 2 2000 with no success. The commands for setting temporary voltage from the black single fan models work OK but it seems the permanent voltage change does not work.
I have no prior knowledge of CANBUS programming either, so I'd like to be sure it is possible before purchasing a CANBUS adapter. From your comments it sounds like this power supply should be suitable for permanent programming, so I will likely take the plunge.Merlin wrote:from the 3000w flatpack theres no "newer" version.
it is "HE" just for his 3000w and size.
double fan, 3 times louder also without load.
but absolutley nice 3000w on same size of an FP2 HE (2000w)
about programming i cant help. never had one. rare pieces out there.
