Help!
Pressing a Li-Po battery to make it fit?

Below is an e-mail conversation I had with a customer support representative from http://toysheli.com.

The two 7.4v 600mAh battery does not fit into the battery compartment of the Avatar YD-711 helicopter. The length of the Li-Po is suppose to be 40mm or at least should be less then 46mm but I measured it and its closer to 48-50mm. I attached some pictures of the Li-Po next to the Avatar battery compartment and with a millimeter ruler. If you have ones that fit please measure it properly that it will fit and ship it to me otherwise I would like a full refund. I waited patiently for one month and got it today (9/19/14) and was very disappointed that it does not fit. Please respond promptly with full refund or exchange (only if it fits!) and if you want a return please sent me a label because this is a seller product issue and not a customer change of mind return.

All sellers responses are within 6 hours of my original email and the third response ask me if I could press it to make it fit (“make it a little shorter”). I am new to Li-Po batteries and pressing on it seems to be a bad idea to me because from what I know they are sensitive to any damage like dropping them on the floor. Is what the seller asking me to do wrong or is that ok to do?

So, does anyone have an answer? Pressing the Li-Po to fit a reasonable request from customer support or is that a very bad idea and why? Since I believe its not a good thing but I have no concrete facts about that please provide expert knowledge so I may respond with conviction. Thank you for your help.

It's a very bad idea to squash a LiPo to make it fit.

The reasons are (1) you may damage some of the connections if you squash the end where all the wires are, and possibly even short-circuit something and, (2) if you squash the cells themselves you are highly likely to damage them internally.

At best, you'll shorten the life of your battery; at worst it'll go up in flames due to a short-circuit or internal damage.

Thanks again Abenn. I will respond to the supplier with the information you provided here.

It's really hard to find a replacement Li-Po for the Avatar YT-711 and when I found it I made the order with this supplier. Too bad it didn't work out though. I have a hard time finding a good supplier for this replacement battery, does anyone know of one that has it?

The original battery is a S2 7.4v 600mAh mini JST L: 40 H: 17 W: 25mm
The battery compartment fits battery size within 45x17x28.
