Three days ago…running with all bars lite. Slowed down and all bars go immediately to the red and into turtle mode…error code 15…low charge. Recharge and all fine until….  
Today…after a mile. Immediate stop of electricity and immediate no power. Beeping sound…error code 88 very lightly in display….could barely see it .  
Seems more electrical than drive.  
Thanks

**an update…li let it sit for an hour or so and problem went away. I guess overheating was the cause. Now the question is why overheating**

Well…when I couldn’t find error code 88 in any gem publication. The error code I found was for a treadmill…ooops. But seems to hold true

It would be helpful if you provide some details about your car.  
Year,  
Batteries,  
any mods?

When was the last time you did a full battery check-up?  
How old are they? Properly watered? Balanced?  
Are all your connections shiny, clean and tight?

That is usually what causes power glitches like the one you describe.

For example- This is NOT a pic of a clean battery connection.

Here is another example of why you should _ **at least** _ lift your seat for a look around every now and then.

Gem is a stock 2005 with 26k miles. Current engine replaced 3 years ago. Controller rebuilt 3 years ago. Batteries arm new 4 years ago. Shocks last year… all else stock.
