Andy I am using a ETX900 in my Legacy that is 8 years old and I would like to replace it. Do you make a direct replacement Sodium battery for the ETX900 and how much would it cost and what is the delivery time?

Do you need the same dimensions ? or, is there some extra space ?
Do you want more Ah ?

Yes I need the same size as the ETX900 case. I have the battery mounted in a aluminum battery box that is an exact fit for the PC680 size battery. The same amp hours or more than the ETX900 has. Thanks

Hello. I would like to research a possibility to change to sodium Ion battery for my 360 as well. I currently run an EarthX ETX680C. Do you have a similar battery replacement for it? Unfortunately it has to be the same size as the EarthX battery because there is simple no more space for a battery behind my panel.

Height and width limited

well, unfortunately, there is nothing that will fit those dimensions.
Does it have to be behind the panel ? doesn't seem to be the ideal place for a battery for easy access.

Do sodium Ion batteries have to be larger than the others?

To answer your question: I think it is the most reachable place on my plane. I use the rear of the plane often for NOS tanks, hence I didn't want the battery be in the way or in danger of a heavy tank falling on it or hitting it in the loading process. Regarding easy access to charge, I have that covered by installing a quick coupler to give it easy power on the ground. And yes, it is cumbersome to reach when servicing, but I can take the battery in and out when the glareshield is removed. BUT isn't EVERYTHING cumbersome to work on on these small planes? That's why we love them. They are sooo snuggly.

yes, Na cells are bigger than Li cells, thus more space needed . I suppose the battery could be split into two parts....

Unfortunately it has to be the same size as the EarthX battery because there is simple no more space for a battery behind my panel.

Erno: How about using this space:

That's where my header tank lives, Bob. I couldn't put a piece of paper in there after the header tank is installed. These airplanes are very small and we keep trying to put more and more stuff in them. I sorta hit the limit already, or will soon. Some water injection still has to fit in somehow, and perhaps a smoke system. We want to look cool after all..
