I wish they had a battery that would work for me
I have a unique electrical system. Due to all electric air conditioning I need 24 volts and a lot of charging capacity so my system is built with 2 odyssey 680 batteries in series to make 24 volts.
I tried using a plane power 24 volt 70 amp alternator but that was not enough. The AC alone pulls close to 50 amps resulting in a discharge when operating at taxi RPM.
The next alternator size available was the new Plane Power ALT-FLEX which is capable of 150 AMP at 28 VOLT. This thing works great for my application. It is just loafing but here is the deal.
The EarthX batteries have a maximum charge rate that you are not to exceed. In the case of the ETX680 the maximum rate is 60 amp. Even the ETX900 is not enough it has a max charge rate of 80 amp. The only time this would be a problem is if I ran the charge down (
Like the scenario that happened to Vic ) and then started charging the drained battery, the large Alternator would initially charge the battery at a higher rate than specified and could cause a failure (not sure what failure mode. explode? Fire?). Make sure you match your components with your charging systems.
