Posted December 23, 20204 yr 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:
December 23, 20204 yr Author No. I expect the results would be pretty much the same as with the motors I've tested.
December 23, 20204 yr 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?
December 23, 20204 yr 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?

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.
December 25, 20204 yr 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.!!
December 26, 20204 yr Very interesting. It would be nice to see a comparison with the 9V mains train regulator also.
January 31, 20214 yr 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.

February 13, 20214 yr Hi, I was using lithium before, the NiZn are stronger. Also, my Energizer lithium report 1.5v, while NiZn 1.6v
