Check the Amp Draw Before Converting to Lithium Golf Cart

When looking to convert to Lithium Batteries DO NOT just look at Volts and Amp Hours. Check your golf cart's Amp draw and the max Amp output the new batteries can handle before buying new batteries.
Here is us testing the Amp draw on our golf cart.

This should be the top of RU-vid. Cool live testing of how to understand the big picture

Following up as I see there is a new comment. I have not had any problems since the installation last year. I used the Epoch 36v. I do not have stock tires but they are not big either. I did a few tests on flat ground with four people on the cart and punching it and no issues.

My concern was going up an incline. On a flat plane with two passengers my cart will consume 150 to 180 on acceleration and settle around 50 continuously. I have a configurable bms and have it set to protect after 5 seconds at 300 amps. 400 amps will trigger it in 1.5 seconds. 500 amps instantly shuts it off. I’m running 16 lifepo4 40ah 10C continuous discharge cells. I get around 8-10 miles on a full charge. Some would argue that’s not enough. I find it to be plenty. The kicker is that I can charge the pack from 0% to full in about 90 minutes which is never really the case. I usually run the pack down to 40%-50% then charge it up to full which only takes a half hour or so. If I’m going on a long ride I bring my ecoflow and charge it in between stops.

What battery did you use? Programmable BMS sounds necessary.

@@sunnyhillfarm I made my own with 16 lifepo4 40ah cells in series. The cells are rated for 10C discharge or 400amps discharge continuous. Though I’m only discharging around 1C or 40 amps with normal cruising speeds.

Sounds as if you need a minimum 96Ah LiFePO4 3x 48V 32 Ah. Add a 4th 32Ah batt if necessary for 128Ah.

What battery did you buy? I have the same concerns.

@sunnyhillfarm Год назад

Signature Solar 48v EG4. It did NOT work with my golf cart. "battery technician have informed me that the clamp meter used in the video does not detect inrush current, the amperage draw is happening too fast for the clamp meter to measure it and a clamp meter that can measure inrush current would need to be used for testing." I will not be trying to convert this to lithium now. Signature Solar was nice and helpful, but I don't think my golf cart is able to do lithium (at least any on the market I've looked at)

@@sunnyhillfarm dang it, I have an EZGO with a similar lithium battery and it throws the BMS into protect mode if I do any hard acceleration. My Trojan are shot, so it was nice to get it running again but disappointing to find it cutting out when the protect kicks in 🥲

@@healeydave Yes, I lost $200 shipping my lithium batteries back. I'm still running on my old batteries that only go 2 miles. I'm trying to convince my wife to let me convert they whole system to navitas or something...

@healeydave 2 месяца назад

@@sunnyhillfarm To be honest if I’m careful, the cart already flies better than it ever did and I don’t need any more power, plus I’m not really interested in doing all that work. Oh, I just remembered, I installed a personality plug years ago to try to get more speed out of the old stock system. I wonder if toning that back down will help with the amp draw?

@healeydave 2 месяца назад

UPDATE: Took the damn cover off the controller and noticed I had already removed the personality plug, Doh! I did run the cart around there garden again though and it works really well, its just when I push it hard, its obviously exceeding the max current draw of the BMS which engages Protect mode. Returning my battery is not an option but I did pay a very good price for it, so my Plan B is to use the cart carefully until I can get a 2nd battery. If I connect that in parallel, I am thinking the current draw will be shared across both batteries and hopefully solve the problem. Its a bit of an over kill solution and I imaging my range will end up being insane but its still the cheaper option than having a battery lying around that I have no other use for.
