Re: Anyone tried RoyPow lithium kit yet?
I'm headed that way this weekend. Do you have any in stock?

Make certain to have the OEM State of Charge, SoC, meter installed with the battery. The existing lead acid battery SoC meter is mostly useless as the power/voltage curve is linear to near the end of the battery's capacity. I also have ran the numbers on the 60 to 65 mile range OEM claim and based on the meters reading vs. miles travel the claim is accurate. |

Re: Anyone tried RoyPow lithium kit yet?
Anyone have any updates on lithium upgrades after using them for a while?

Re: Anyone tried RoyPow lithium kit yet?
I've been running a RoyPow lithium for several months on my EZGO TXT. I have a stock motor, Alltrax 500 amp controller (programmed to 460 amps), 1/0 gauge cables, and I am running 30 mph on 22" tires with great torque. Real-world range is 16-24 miles (with sound system, lights, and other accessories) depending on driving style and terrain. I previously had Trojan T-875s and would get 8-13 miles on a full charge down to 48.5v-18.4v.

Range is dependent on numerous factors, but as another data point to your 16-24 mile figure, my test produced 44 miles. Conditions were: Onward cart, 23" tires, Navitas 600a controller / AC 5KW motor, Speed capped for test at 22.5mph (70% of mileage for test was at that speed - rest was stop and go - no tire chirping acceleration - just "normal" neighborhood driving). All paved roads / paths. No hills. One person onboard. 100% charge to start. Test end just as last bar went out (per-cell voltage still in a "safe" state at that point). This was a cool weather test during winter (around 60f) - warmer weather will increase range slightly (and that has proven to be the case for me). I tested carefully and recorded voltage at each "drop" of a SOC bar on the RoyPow SOC meter, and drove the same way for the entire test (test completed all at one time). With temperatures in the 90s where I am now, my range is around 5 miles / bar under similar speeds / conditions to my original test, where then it was around 4.4 or so. You can search back for a very detailed report I posted around January or February of this (2020) year if you want to learn more about range and driving conditions when using this battery. If you go WOT everywhere you go you'll go less far. If you stick to stock speeds, you'll go farther. Drive with some of both - well, somewhere in between. As an aside, I did some basic tests before I changed to the Navitas AC system, and at test speeds in the low 20s it used less watts per mile than the stock Club Car motor / controller did, so not sure how Alltrax DC motors / controllers fare. I would assume AC drive is likely somewhat more efficient at all speeds, but I only tested for this in the low 20s - it may be less of an advantage at higher speeds, or have none at all - Not sure. |
