I'm guessing you saw Jerry's post on GCMod? We paired it with a Navitas 5kw AC kit.

It runs pretty well. The same cart with new Trojans went 0-20mph in 5.9 seconds. After installing the RoyPow pack it ran 0-20 in just over 3 seconds. Major power boost however its not as powerful as a diy lithium setup. The RoyPow pack is limited to 250amps discharge. If you go over that the pack shuts down to protect it.

It's a pretty good buy, if I wasnt as electrically inclined as I am I would definitely consider it. It comes with a 5 year warranty too.

Yea thatís what Iím referring to.

I could figure out how to do a DIY kit I just donít have the time.

Looking a doing this lithium setup with a 5kw ac kit also.

Will have 25Ē tires and want at least 20 mile range with enough torque to go through mud climb ditches without bogging down.

I just wondered if anyone has actually purchased any from him before I send him $1800.

You'll easily check all those boxes with that setup. After a little tuning we were able to get it to pop a 6in wheelie on 23in tires.

AC kits dont provide the low end torque that a DC motor does but they have great mid range torque. Pulling hills and such wont be an issue.

It takes a while to get those packs in. The one he is running took 4 or 5 weeks to get.

250amps discharge? What would the discharge amps be for a normal 6 8v watered pack

Depends on the batteries capacity and quality but 500-600 plus peak amps is do able probably more in some cases.They wont sustain it but in quick bursts like accelerating they can.

That is a good price for lithium though I would like to have it just to cut the weight down. When these batteries go i am switching to something like this. I know this would void the Warranty but there has to be a way to eliminate that safety that limits the amp rate or some way to increase it. I am trying to keep up with the lithium talk here so i am prepared when the time comes. So far i think this is the best option for me. I watched some if the lithium builds and its way over my head. Thanks for the reply

When you do this, you might want to try it on your stock DC motor and controller before spending coin on the AC setup. You may find you like the performance on DC. Plus if you do the AC conversion later you'll know separately what performance improvement was due to the lith pack and what was due to the Navitas.

I bought the 300 amp alltrax and still run the stock TXT48 motor on my 57.6v lith pack, with 23" tires I can pull a big fat wheelie on flat pavement without issue. The most I've pulled in the very limited logs I captured was something like 289 amps on accel. With the weight loss you don't need as many amps to accelerate.

Good idea.
Thanks.

Picking up a 2 year old Beast 48 golf cart this week, it has a 600amp Navitas controller and 15.9hp D&D motor.

Will be getting lithiumís around tax time.
