RcHov Posted February 20, 2022 Share Posted February 20, 2022 (edited) Hi All, Been following the forum for a couple of years, and so far all other posts have managed to answer my questions. Could I power an engine heater via 2 x 7.2 v NICADs/NIMHs? I’ve got a 7.2V 1800MAH NICAD and a 7.2V 3600 NIMH (used for a rotoshart) so wondering if they would power the heater ok if connect them in series, after making a Tamiya to XT60 converter. Cheers!

Fred barlow Posted February 20, 2022 Share Posted February 20, 2022 I wouldn't, you have 2 different capacities and 2 different cell types, but depending on the voltage spec of the heater you could get another NiMH pack the same as you've got and series them up 1 Quote Link to comment Share on other sites More sharing options...

I've got a 2S lipo too, so either go with anither lipo or NIMH pack, but rather go with NIMHs as less volatile. Cheers again Quote Link to comment Share on other sites More sharing options...
