A few weeks ago I stated that I intended to add a 7th battery to my 2002 two seater. This is the result. Three/four miles of extra range. Lots of acceleration. 42 MPH but limited to 38. The last 4 MPH EATS!!! range, True 22 miles range on turf mode flat ground.@ about 30 MPH TECHNICAL 2002 2 seater 8.9 gearbox 21" diameter fat tires on 10 inch rims (205 65 10) 7.5 RFF Black Motor (My Mods) INWO Spoof. (I asked INWO to make me a modified Spoof to allow 2 more volts thru to better balance controller usage algorithm) I have the program set to 1 instead of 3 at present but it still alarms too soon. 31MDC batteries from O’Rilleys (trolling motor/sweeper batteries 105 AH. I charge 6 with the Zivan 7th with a cheapo. The Zivan will charge 7 batteries to 85/90% Total cost $115 Rodney ---

That’s nice, where did you put the 7th battery? That is a cheap upgrade from someone that want’s a little extra speed. Are you using an MM from David as well? ---

Battery is in the trunk. T2 controller Magic Magnet is not required.

Rodney, I am not following you on the spoof stuff. Is that required to add the extra battery? I would like to add the range, not the speed but didn’t know how to do it. Rudy ---

@Old_Houseboater measure your spoof so I can send a corrected one. I don’t remember what you have. Seems that 12v would be perfect. ---

> [@Old\_Houseboater](#): > > I have the program set to 1 instead of 3 at present but it still alarms too soon. two questions: 1. I’m assuming this is a pre-set program in the controller? If so, which controller is in your vehicle? 2. Still getting alarms? Third question not related to the programming: 3) think this is doable with the sock 5hp motor and 10.35 gears (I think the '02 longbed had 10.35 gears - I have to verify - I could have it backwards). Running the same battery as you, but from NAPA auto (#8231) as the O’Reilly batteries out here are Interstate made in Mexico w/ sub-par quality lead. NAPA still has the Dekkas. Not looking for 42 mph, hell, I’d be happy with 32. 35 I’d be ecstatic. Thanks ---

I think that #1 is Ok for now i installed a volt meter so it doesnt really matter. In a message dated 5/22/2019 3:49:00 PM Eastern Standard Time, [electricforum@discoursemail.com](mailto:electricforum@discoursemail.com) writes:
