Sariel Posted December 23, 2020 Posted December 23, 2020 I have recently got my hands on Ni-Zn batteries, which can be considered a compromise between standard alkaline batteries and the Ni-Mh rechargeable batteries. Long story short, they can be recharged and still offer a LOT of power. I was able to get 10 KM/H out of my modded 42124 with Ni-Zn batteries compared to 7 KM/H with standard alkaline Duracell batteries. More details: Quote
1gor Posted December 23, 2020 Posted December 23, 2020 Interesting video; did you try to test batteries with PF motors? Quote
Sariel Posted December 23, 2020 Author Posted December 23, 2020 No. I expect the results would be pretty much the same as with the motors I've tested. Quote
1gor Posted December 23, 2020 Posted December 23, 2020 Probably since L and XL motors are practically the same with different suit... Quote
blondasek Posted December 23, 2020 Posted December 23, 2020 Awesome. Gladly I can buy them in the country I am living currently. Now I need only to wait for Buggy to be released. PS. out of topic, did you think to change the gearing as now you have more power? Do you think it may work on this batteries? Quote
2GodBDGlory Posted December 23, 2020 Posted December 23, 2020 I have ruined a PF IR receiver by powering it from a 9.6V hobby battery. Is there any chance that these Ni-Zn ones, also at 9.6V, would also cause damage to receivers? Quote

Do you think it may work on this batteries? Yeah, I suppose with Ni-Zn batteries there may be some leftover power to try a very slightly higher gearing. I'm not going to test that though, I'm focusing on using these batteries with the LEGO rc buggy motors. Quote
sirslayer Posted December 25, 2020 Posted December 25, 2020 I've been using NiZn for over a year and the only gripe I have is that out of 24 batteries, 14 of the are still usable after 1 year time.. depending on the brand, (some are really bad) some batteries will stop holding a charge after 6 months time.. There are some tricks to revive them in the Youtube webpage.. My understanding with the Powered Up and Gen 1 IR receiver have a 10.1 volts limitation but with my experience with the higher voltage didn't affect performance or harmed my Lego electronics. Use them with caution.!! Quote
aeh5040 Posted December 26, 2020 Posted December 26, 2020 Very interesting. It would be nice to see a comparison with the 9V mains train regulator also. Quote
cammellostanco Posted January 31, 2021 Posted January 31, 2021 Just installed NiZn batteries on 42099, WOW, what a difference compared to NiMh. Let's see if the hold many recharge cycles and also let's hope I do not overstress the motors. Quote

cammellostanco Posted February 13, 2021 Posted February 13, 2021 Hi, I was using lithium before, the NiZn are stronger. Also, my Energizer lithium report 1.5v, while NiZn 1.6v Quote
