trojan t-45 vs deka gc10 for range increase

beach cart

I'm new so please correct if I am wrong. I have a lifted 36v 2007 txt with deka gc10 new batteries. I am getting about 6 -7 miles on a full charge, or better explained, I head home when the state of charge meter goes to orange from red with 3 tics left. Will going to t-45 or deka 45's increase my range alot. What else can I change to increase range. Speed is good 27 tops with standard motor. Standard brakes are ok, but are the mechanical rear disc's worth it

New batteries are only about 75% of their potential. Full power can take up to 20-50 cycles. Do you mean T145? That's a big battery. It holds about 10% more that the regular T105, so you would see another 3/4 mile according to your info....

27 mph from a 36v cart?? Dang, thats great.

Do a search for what guys are doing to improve performance on these things. They clean connections on the batteries & the electronics, install bigger gauge wires, check water levels in the batteries, check voltages on the pack, etc.

Not many guys using Deka batteries in this forum... that I've seen. But I work for a big restaurant supply outfit that has a ton of electric forklifts & pallet jacks.... machines that have to carry tons of weight for 8 - 10 hr shifts day after day. And Deka is used a lot.

Good luck. Hopefully one of the sparky experts will jump in with more specifics.

I am still learning all the parts and have been riding on streets only, it is street legal and tagged, there is a blurring amount of info on motors controllers etc. distance between charges is my main thing, but want to learn more.

t-145 is what I mean and from my research so far its between the trojans or us batteries same amp hour

Scotty probably has empirical data on the difference in run-time between T-105 and T-145 batteries and I don't, but the published difference in discharge minutes between the two is 30, which is 26%.
(@ 75A Rate: T-105 = 115, T-145 = 145, Deka GC10 = 105 and Deka GC45 = 145)
Your cart is obviously drawing a lot of Amps, so the Peukert effect is high, but even with a factor of 1.6, you ought to get about 15% more run time.

Technical gibberish aside, 27 MPH tells me your tires are over 25" tall or you are revving your stock motor over 4,500 RPM.
Care to share a little more information about the cart?
Is it a PDS or Series?
What size Tires?
What Controller?
What gauge cables?
What is the battery voltage is before and after.
Is 6-7 miles one way or round trip?

Even if it is one way, 14 miles on a full charge seems like a mighty short distance for a full charge to me, but my cart is a stock PDS that only does 18 MPH. YMMV.

Like Scotty said, you won't get your batteries up to full storage capacity until they have been broken-in properly.

Also might be that your charger isn't actually fully charging them.
What is the battery voltage 6-12 hours after the charger shuts off automatically? Should be 38.2V or so.

Be patient, the fog lifts after a while.

Your cart moves at about twice the speed it was designed for, so it travels about half the distance that was designed into it.
To travel further, you have to carry more electrical energy with you. (In the form of chemical energy stored in the batteries) and/or increase the efficiency of the transfer of electrical current from the battery to the motor.

Bigger cables, solenoids, controllers, F/R switch (if it is a series cart) and a more efficient motor are about all you can do for efficiency.

How much stored energy you carry is determined by how big and/or how many batteries you can stuff into the space available.

Going from a 36V system to a 48V system would give you more speed and range, but the range part only if you increase the number of 6V batteries from 6 to 8. The higher voltage make the cables and components more efficient because less current is needed to do the same amount of work, but you still can't get something for nothing, you gotta have the battery storage capacity to get the range.


Flip a coin.
Seriously, there isn't all that much difference between them. EZGO installs Trojan Batteries in their carts, Yamaha installs US Batteries.

Personally, I would add up all the shipping charges, recycling fees, taxes, fuel burnt to pick them up and return core, etc, and go for the lesser expense.

YES! Best money you can spend on a cart in my opinion.
You also need, new wires, new controller, new batteries (48 volt upgrade), new soleniod, new F&R switch, new volt meter, lift kit, new wheels and tires, voltage converter...

Hello, my name is Scott and I'm a cart addict.

That is a good speed for a stock controller and wires on a stock motor. I would see what the charger is doing when it's charging stay with it and watch it over the full cycle. If you are driving the cart everytime till it starts blinking this may damage the battery over the long haul. New batteries getting deep discharges doesn't promote long life for the battery. On a good set of T-105 trojans I have gotten over 20 miles at Myrtle beach SC on flat ground all pavement riding. Running 23" tires @ 24 MPH.

My controller, wires and motor are stock. Have a Jakes 6" lift kit installed. Had gears changed to 8-1 from stock, the tires are 22.5" atv height 10.5 rims.
The charger is stock ezgo auto shut off. The speed was checked using a GPS handheld which could be off by ?. Used the driving a car behind me MPH test.

First thanks to all of you for all the replys, I have read the forum a couple of months before joining, and just riding after work is the best. Best toy I have ever had.
