The only issue with lipo batteries is not to let them discharge below a certain voltage as once they are discharged completely they are usually dead.

Let me guess. No one knows the value of that "certain voltage". loll
I thought the opposite, that lithium you could discharge completely and these things would never die.

I used the Battery Tender BTL35A480C and Battery Tender 022-0198LI Green Lithium Junior Battery Charger in my LGT race car. The 480 has plenty of power to start your engine a several times in a row. However don't leave it without the charger more than during the day at the track. I left mine for 4 days once in the garage and the ECU drew it down to zero. Luckily it was undamaged other than I had to hit with a more powerful battery charger, the little battery tender charger wouldn't kick off the charging.

The ECU? It was still on when the engine is off?
The only thing I leave on is my cluster LCD displays (2 values are showing with a very very low brightness that I almost can't even see). Doesn't draw much and I charge it every week. I also have a kill switch which kills everything.

Using the same battery, only 30 miles of driving but many starts, no issues.
