Top up batteries faster with plug-in charger in-parallel?

Push the boost button to get four hours at FULL THROTTLE.

See page 2 & 3 of the manual

Usually the battery -charger- will back the WifCo down to sheer uselessness.

60-70 amp battery chargers are not cheap. But you may be better off buying a 100-amp model (BFL13 has a lot of experience with doing this). Maybe he will chime-in. Then chop the WifCo when using the charger.

The WifCo makes a good bench 13.6 volt power supply and little else.

If you have the 68100, it has a button on the front to select bulk

If not, then another charger will not hurt anything, but the battery will not get anything from the WFCO after its voltage goes past the WFCO's voltage. After that, the only amps you will get is from the other charger that does go to 14.x volts.

I have a 100amp PowerMax that also has PF correction, and it does bulk at 14.8v. I run that and my VEC1093DBD together (also 14.8) and get 140 amps constant (no tapering) until battery voltage reaches 14.8 when tapering starts in the absorption stage.

You do need a generator can power all the chargers at once though. My Honda 3000 can do a total of 130 amps of non-PF corrected Vector chargers, or it can do 150 amps of the 100 PF corrected plus 50 more amps of Vectors.

The only way to get a 90% charge on the deep cycle batteries in a three hour time period without gassing out battery fluids is to use 14.4VDC for two hours and 13.6VDC for the remaining one hour...

I believe I have read where some of the guys that live full time in their trailers do just that with two or three VEC1093DBD Portable smart mode chargers in use in parallel...

I would just get a good quality smart mode 40AMP Battery Charger like the B&D VEC1093DBD and just plug it into the generator and direct connect to the disconnected battery terminal to charge them back up in the three hours until you can replace the WFCO products...

I wired in a PRD9260C 60A Smar Mode charger in the same daisy chain battery feed line on my setup and then just turn on the proper circuit breaker to use either the WFCO unit or the PD9260C unit. My PD9260C has the double DC CONNECTOR to allow for daisy chaining the 4WG DC cables. My WF-8945 was brand new and I hated to just throw it away so now it is used as a standby unit. When camping off the power grid I totally use the PD9260C which goes into smart mode charging when you want it to...

My wiring setup looks like this using both the WF8945 and the PD9260C...
