Advice using a NiMH tamiya 7.2v 4500mah battery for the Hobbywing 1080 esc

[stevo1810]

Hi,

I'm new to the forum and new to the RC crawler scene and have purchased my first crawler the Carisma sca-1a.

I am looking at upgrading the ESC to the Hobbywing 1080 as it has the option of the PWM frequency change to get rid of the noise at low throttle. I am wanting to keep the battery and use a 4500mah 7.2v NiMH tamiya connection and change the connector. It says it is compatible but I have only read and seen people using lipo batteries but the NiMH batteries seem safer and more suitable for me.

My question is will the NiMH battery perform fine or will there be a big difference if I did end up using a lipo battery? Has anyone used the ESC with NiMH batteries?

Thanks

Welcome to RCC! The nimh battery will be fine, however the top speed and run time probably will be shorter. Just be sure to check all esc settings with the included programming card. I'd use an XT-60 plug on it, as the Tamiya plugs don't make good electrical connection, get loose quickly and can overheat and melt the plugs together.

Thanks for the quick response
I'm in the UK and it seems the only NiMH battery with a xt60 connection is a USA Venom.
I think I will just bare with the tamiya connection and see how it goes.
Thanks

Soldering irons are pretty cheap. You don't need a fancy one, a 40w weller pen will do fine for this hobby. Mine gets plenty of use to justify the expense.

I've watched some videos on YouTube so I'm some what of an expert now (joke) seems easy enough so will just change the connectors on the battery.

One question, for charging could I still use a NiMH only charger? And use an eBay adaptor plug from male xt60 to female tamiyay? I assume it shouldn't really change much apart from how they are connected?

Yes, just use whatever charger you already have. You're exactly right, connector types don't matter as long as the power flows with the correct polarity.

And just to reiterate - when you set up the esc, make sure it's set for NiMH and not LiPo or you will have issues..


PS
LiPos aren't nearly scary as dangerous as the internet/media makes them sound and they really do perform IMMENSELY better than NiMH. You'd be well advised to plan on making the switch when the NiMH batts you already own expire (generally about 2-3 years max).

I have a venom 6cell NiMH battery pack that is 20+ years that is still working

I use a 3000mah NIHM and get well over an hour trailing time. I'm also running the 1080 esc and love it.

Enjoy, jjp

Just a little tip/reminder. If you haven't seen it on any of the threads on the forum, be careful not to let the 2 battery leads touch each other and short across the battery. Seems like more than a few people have done this. Remove 1 lead from the connector and tape it up. Then remove the 2nd lead from the connector. Solder the 2nd lead to the new connector, remove the tape from the 1st lead and solder it to the connector. If you are going to shrinkwrap the soldered joint, don't forget to put the shrinkwrap on the lead before you start soldering. Once in a while I still forget to do this, in too much of a hurry to get it done.
