Semper Fi from another Shellback. Marine Corps UH-1N pilot - 1977 - 1988. Great video. Ordered my Lipo battery from Palmetto yesterday and plan to retrofit this weekend if it arrives on time. I will do the fiberglass floor , ratchet the battery in and Dremel the hole for the gauge. Great tips and advice.
@@StewBernard Welcome aboard shipmate! I recommend not mounting the gage with the bracket so you can unplug it before you start mowing. The gage tends to blow out when there is a surge when you go yo engage the blades. That is what I do with the new replacement gage I got. I might find the power wire and splice in a toggle switch to turn it off before I mow.
The battery gauge stopped working after I engaged the blades. I contacted Palmetto and they send me a replacement, free of charge. Unfortunately, when I installed the new unit, it happened again. I searched the Palmetto website and other online sources, and a clear explanation to me has not been provided. Have you determined, what is causing the problem? The lawn mower has plenty power, but I would be nice to see a battery status. By the way, it does come with Bluetooth connectivity, and it is not working as well. I will delete the app and reinstall to determine if that would work.
@@saltyshellback It appears to me as an assumption, when the motor and the blades are engaged, the battery gage is short circuited in some way. I will contact Palmetto and request another gage. Will you do any modifications to allow you easier access to read to gage, instead raising the seat and taking a reading for each mowing? Also, have you tried the blue tooth feature?
I just received a kit thru Palmetto and it included a replacement step down transformer. I called them because it is not shown in the instructional video and apparently this is a new addition to the kit because the voltage is too high and frying customers battery gauges.
@@chrisflynn4063 same problem, got the same "fix-kit". Not sure how to install.. if you have already done your's, could you please show the rest of us how you did it
@@safriedrich1631 Long story, but i am still working with Epoch battery to figure out the correct wiring. from what i've learned, you will want to use the existing OEM step down transformer/reducer because it has an additional green wire that the "fix-kit" reducer does not. This green wire appears to provide power to the key switch. I unfortunately went thru the process of removing the OEM part and am now waiting on a replacement to finish the job. Will update when i know more.
@saltyshellback Thanks for the great video. I am about done but the one question is around the “blue wire splice”. At 11:52, It looks like your did not cut the original wire before the connector, rather after. I am OK either way, just want to be sure I am seeing/doing it the way you did. And can I assume it’s 16 gauge wire? Again, thanks much (from an old Army Cobra jock)
@@EricAnderson-j7l I've slept since then so I can't remember exactly how I spliced the wire😄 I think I used either a bullet connector or blade connector to hook up the spliced wire to the original connector in one end and put an eyelet connector on the end that goes to the battery. Tip: DO NOT MOUNT THE GAGE! Leave it loose in the hole and disconnect the gage before you start mowing. The gages seem to stop working when you start the mower blades because of a power surge.
@@saltyshellback Got it. Question was more about before the connector or after (as that’s what it looks like in the video). Seems kind of crazy that you need to plug and unplug. I think I saw something else where they had a kill switch or something.
Thanks for this! Quick question... how big is your property? I've got a little over 2 acres. Looking to change my RM300e to Lithium and trying to estimate how far that battery will go.
@@saltyshellback OK, thanks! My 2 acres includes some slopes as well and that may eat up more power than your property but I never try to complete it all in a single day anyway.
I literally tried to install new lithium batteries in my Ryobi rm300e this week but ran into an issue. They’re a total of 4, 12V batteries but after hooking them up in series push 53V. When I try to start the mower, the lights flash then everything dies. All the wiring and 100amp fuse are good so I’m guessing it’s the contactor. Is there something you did to get the BMS to not shut down since in your case you have pretty much the same voltage?
@@elviejo565 I'm not sure what could have happened to your mower. I know that there were a couple of original connectors that had to be rewired to the new battery. I think the blue wire that went to the old charging port connector has to be wired to the end positive terminal of the series of batteries.
Watch the video at 11:52 it shows what the blue wire that goes to the positive terminal looks like. You have to make a jumper wire with an eyelet at one end for the battery and I believe a bullet type connector on the other end.

Interesting! They are getting popular!
@@eltenda I like the electric mower because it's much quieter and cleaner to keep up with...when it's running right 😄
Ohm my God! I love watt you did! I dont want to speak -ly so I’m going to leave a + comment. I got a charge out of this video.

That video was epoch.

I have a Black & Decker 20v string trimmer...=)

If you still have the problem it could be due to current inrush causing the bms in the batteries to turn off. Do a search for Ryobi precharge circuit
What is the measurement of the battery compartment?
@@Papa_Aurelio Not sure.
