Pete and his team are here to help. Here is a new thread related to the Delta Q QE they made for Ezgo/Textron over the years. If you are looking for a replacement you can follow this link to the product page. Replacement ChargerAll Heated Up!
Ezgo Golf Cart Battery Charger 48V Powerwise QE Fits Rxv TxT I received charger very promptly and it looks to be in good condition. I charged cart batteries with it and did notice it got hot. It appeared to be charging ok. Green light was blinking. I don’t recall the original one I had getting that hot. Is that normal? John John – Thank you for your recent order… Just wanted to drop you a line to answer your question and address your concerns. All battery chargers will generate heat. So they do get hot. It is usually related to how hard they work to charge up the battery bank. The harder they need to work ( The longer they are charging the hotter they will get ) If your batteries where quite low because you where without a charger for a spell it just needed to run longer than usual. Keep an eye on it for a few more times to be sure once back in the normal use. Only other scenario is if the batteries are quite old and eventually become stubborn about taking a charge… In this case the charger will just keep on charging until the batteries reach a certain voltage or the automatic charger timeout – commonly a 12 hr feature. Power On… Pete Why is My Charger Making Clicking Noise Pete: Why does my charger make a clicking sound every few minutes? It’s plugged into power, but not plugged into the cart. I have it placed in a sheltered area, but the sun was shining on it this morning. Thanks.– paulmdavis
That is the metallic sound of a relay clicking as it tries to make a connection with the cart. If not plugged into the cart I do not recommend leaving plugged into the wall. This will help avoid the charger from being fried via a lightening strike or getting a power surge from the wall which in the event could /would cause damage to the charger.

Have 2 red flashes on charger. New batteries
Rick – Good day! Thanks for your inquiry. 2 flashes represents voltage issue. either to low or to high. See link below to another blog article about such lights.

Sometimes when installing new batteries “If just done” Installer will forget or over look connecting the little wires which go to the charge recptacle on the golf cart, hence not connecting to the battery bank. So being when you plug in the charger to the cart – it does not know it is plugged in as it does not sense voltage. Double check the wiring cart side.
Check the voltage at the battery bank 48 volt – then check at the receptacle. You should have the same exact number at either location and tell us the circuit is complete. the only other thing in the charge circuit on the Ezgo is the (Temp Sensor) ” The little black box on the negative wire about 1″ in length”… which if blown need to replace the whole receptacle and wiring to the batteries as Ezgo does not offer the temp sensor separately.

After 48 volt powerwise reaches full charge, can it discharge battery leaving it plugged in?
Chuck – The technical answer would be Yes, but realistically you would never really notice it… The parasitic load that charger places on the battery bank would be way way below an amp…. At the standard discharge rate of lead acid batteries at 10% monthly you would never know it… This is where a smart charger like the new Summit Series chargers from Lester come in handy should you be a seasonal visitor or cart sits in storage for long periods of time… It will turn itself on and off and regulate itself without human input or action if left plugged in to cart.

I just put sealed gel batteries in my cart. I have the EZ Go Powerwise QE charger. I have a total of 48 volts. I there any issues with the gel batteries? Any settings required?
Thank you for your inquiry…. Yes I would recommend a smart charger that you can program specifically for GEL. These types of batteries have different characteristics then a regular flooded battery…. and proper charging will allow you to experience the performance and longevity they advertise. That little Delta Q QE charger is not the greatest charger in the world… Just a cheap solution the bean counters at Ezgo came up with to give away with a cart sale. Check out the new Lester Summit II Series Chargers or even the higher end Delta Q Chargers…. depends on if you want to keep the current set up – Charge port or if you would like to mount charger onboard so where ever the cart goes the charger goes with it… https://batterypete.com/chargers/golf-carts/
Hands down considering all the options I think Lester has the best charger on the market again with the Summit II models… and they have the industry best 4 year warranty

Just replaced 4 12 volt batteries. Wanted to give a charge to the new batteries. The LED on the EZGO cart near the charge receptacle gives no indication and the charger gives very faint rapid flashing green light. Did I miss something. Cart seems to run fine.
Harry – No Worries… Sounds like the charger is charging properly, though sometimes the LED light goes out on the cart side receptacles and will not flash anymore. Also see this issue sometimes with aftermarket chargers that replace the OE units. Even though they might be better chargers and better for the batteries… no always compatible with OE equipment. You should be fine, as long as you see the charger lights flashing on the charger. You can always confirm the charger is working if you do a basic touch test after 30 minutes to an hour of plugging it in. If it is really working the charger will be hot to the touch.

I have a E-Z-GO Powerwise Qe charger. Just replaced the 4 batteries, drove the cart, went to plug it in to charge and the charger flashes 6 red lights. Everything I’ve read is saying to get a new one… thoughts?
Chris – Yep…. They are not the best battery chargers. 6 lights usually means internal fault. What can you expect when they give it away with a cart. I recommend the All New Lester Electrical Ezgo 48 Volt Golf Cart Battery Charger. By far the smartest and best charger on the market. Plus it will take care of your batteries even if you went on a 4 month vacation. Comes with a 4 year manufacturer warranty.

I have a E-Z-GO Powerwise Qe charger. The Powerwise Qe charger LED does not light up – nothing. I’ve tried just plugging in the charger to different AC outlets, that I know work, and the LED does not come on. No LED when plugged into the golf cart batteries or when unplugged from the golf cart batteries. I tried to see if there was any voltage on the output of the charger using a multimeter but no voltage appears on the meter – don’t know if that will work without a load. Is there something else I can check? Will the LED light when plugged into AC outlet but not the battery load? Is it time to get a new charger?
Thanks for the help!
Sounds like the charger is shot…. You should be able to see a light when charging but will not otherwise… usually we will plug all in and then check voltage on the battery bank of the cart to see if the voltage changed from the resting voltage….. Though cannot check the voltage coming out of the DC side cord as all these chargers need to sense voltage befoe they will apply amperage if working properly. Lastly these are not the best chargers in the world not even close actually … Ezgo gave these away when you purchased a cart… so cannot expect much from something that was given away….
Pete recommends the new Lester Summit II charger as they are just awesome and come with the industry best 4 year manufacturer warranty. Purchase one today and save $339.00 Free Shipping!
I have the 48V QE Charger and often leave the cart charging overnight. Is this going to drain my batteries quicker or is there an auto shutoff for the charger?
Troy – Always put the charger on the cart after use… to ensure the batteries are fully charged for the longest possible service life of the batteries…. And yes of course all new style chargers have an auto shut off…. The charger is only looking for voltage achieved – once that number is reached the charger shuts off.

Question about PowerWise QE 48v battery charger. Three to four seconds after plugging the charger into my cart a clicking sound (like a relay powering on and off) eminates from the charger and the green light flashes in unison with the clicking. What going on?
Pete thank you for your inquiry…. The golf cart battery charger is basically sensing voltage once plugged in and a relay clicks internally to start the charger…. All new style chargers have to sense voltage before they will turn on and start to apply amperage…. The green flashing light is indicating it is charging…. once charge cycle is complete it should go solid.
Pete’s team
The charger (relay) continues to make the clicking sound every second or so and the green light comes on every time it clicks. I don’t think it is charging.
David – yes you are correct the charger is trying to cycle thru but is faulting out for some reason…. Might need a new Golf Cart Battery Charger…. Checkout several product brands here… https://petesgolfcarts.com/chargers-batteries/chargers/

My Powerwise QE 48v charger does the same thing as Pete’s but the green LED never comes on steady and I don’t think the bats are getting full charge.
1st time owner – green light when I put the charger on (48V EZGO ) – howwill I know when it is fully charged and will it stop charging on its own.thanks
I just purchase E-Z-Go cart battery charger 48 volt how was QE fits rx-3 txt I put it on charge for the first time on Monday and after a while the red light came on and said it was a default to read your manual well I do not have a manual so I wonder what I can do it’s a new charger thank you
I recently bought a 2015 ezgo golf cart & it came with a charger, Power Wise QE model # 9174810. Does it have an auto shutoff feature after the battery is fully charged?
I have a 48v ezgo qe charger it blinks green long and short then goes solid,when i test the battery pack it’s at 38v and all batteries read individually around 12.71 to 12.89 is the charger going bad
Another question when i plug the charger into my cart first should the charger blink at all
Just put 4 new 12v batteries in my cart. The Power Wise QE will blink green once then 2 reds from that point on. I tried my neighbors Power Wise QE and it works fine. Is mine repairable?
No real info here – everything Pete answered can be read on the outter cover of charger.
Are there any replaceable parts inside QE2 ( diodes, capacitor, etc. )
Surely there are replaceable parts such as diode, resistors and such. Though we do not service used chargers. You can try to reach out to several OE or aftermarket re-manufacturers to rebuild units. But by the time you get done shipping back and forth and paying for the repairs – it makes more sense to just purchase a new charger – better brands and quality readily available for roughly the same amount of money. But New product with warranty – so really a no brainer. Checkout our complete line of golf cart battery chargers from numerous manufacturers here…. Currently I would say Lester Electrical is back on the top of the mountain with the new Summit series II line of chargers. Also comes with the industry best 4 year manufacturer warranty.
