I like your battery setup, but I think I go through too much fuel in the spring and summer to power my pump with tool batteries. What I have been doing lately is leaving the 30a charger on the large lead acid battery while fueling. The pump runs faster than normal, and the charger goes to float voltage immediately after the pump shuts off. Do you think I am risking damage to the pump motor doing this?
Don’t think you are hurting your pump motor. Low voltage more of a concern than charging voltage.

Pumps usually have a duty cycle. The Vevor pump is 10 minutes. That’s 110gallons. I tested for 5 minutes and drained less than half of a 5ah dewalt battery recirculating back to tank. In theory could dispense the whole 107 gallons on one battery pack. Don’t have power in tractor shed so the rechargeable battery trick works well. Can easily switch to battery clips and use tractor batteries if needed.

From an engineering perspective would like to see data of actual under load voltage and amps these battery converters deliver with this application. An incorporated digital voltage gauge would be a nice feature.

I doubt you'll damage the pump for the short period of run time it takes to fill a tractor tank.

I was doubtful about the capacity of these 5AH tool batteries at first. I was surprised to find I could empty that 30 gal. barrel and still have half a charge left. I have a couple of 12AH batteries I use in my mower, and was prepared to use one of those but the 5AH work just fine.

I don't usually leave the battery on the pump in the unheated garage. I take one off the charger in the shop and put it in my pocket if I need to pump fuel. I treat the pump just like any other cordless tool.

I may get one of those tool battery converters for my 20v DeWalt batteries. 30 gallons is quite a bit more fuel than I would have guessed a tool battery could pump, with power to spare.
I did have the lead acid battery left over from my truck, which was removed from service at 50% capacity.
Glad to hear I'm not likely to damage the pump by leaving the charger on.... one less thing to mess with!

That is impressive performance. I would not have guessed that much fuel could be moved. Thanks!

There are versions available with battery gauges/voltage meters, but as they aren't built in to the battery, I would not place much trust in the capacity. Bottom line is that I am not sure it buys you much extra information.

All the best,

Peter

In most cases, these transfer pumps don't have to lift or pump fuel to any great height. The pump tank is usually at or close to the same height as the tank you're filling. The actual pump amp draw is usually far less than it's rating.

Even if a 5AH battery wasn't sufficient for how much you pump, have a spare handy just like you would with a cordless tool. Most of us with cordless tools have more than one available.

I did some research and asked around here as well. I'm probably going to go with the Winco 15k. I'm still researching a type of quick connection for it. My transfer switch currently has a 50A twist lock, wouldn't be enough for this one under heavy load.

The WinCo comes with a 60A plug to go into the generator. Just add it onto the cord from the transfer switch (assuming the switch can handle 60 amps).

The transfer switch can handle 200A. It currently has the 50A twist lock on thr bottom of the box. Easy to swap, but I'd rather not have a cord hanging out of it all of the time. I was researching what I needed to do something similar, but I got distracted with other projects.

Winco 10kW. Three houses, barn requires mobility. 0.56 gallon per hour with the B26.

107gallon tank just put into service.

Even with best precautions, running a generator inside is risky. Do have a Miller Bobcat welder/generator in the shop, exhaust routed outside. Run with garage door open and fans running when operating. Always risky.
Anyone interested in the 58 gal version of the Vevor fuel transfer tank, Amazon has a Cyber Monday deal going for 20% off:

I also have a 200A xfer switch (inside the basement). I wasn't able to source a 60A female outlet so I simply have 30' of cord hanging on a hook outside the basement wall that will reach the tractor when needed.
