I meant to say the battery charged in 5 hours on sunday night. Today i got the mmeter and checked the battery voltage...

I didnt word it correctly.

A tender will not bring a battery to a full charge once it’s been discharged. You need a charger to do that. Personally I use the NOCO Genius chargers to charge and maintain my batteries.
 
I used this actually.

I would pull the battery and take it in to get it load tested. If you have a Batteries Plus nearby they will be able to help you out with that.
 
There is a big difference between lithium ion and lithium IRON batteries. Lithium iron are smaller, much lighter (Under 2 lbs vs 10), self-discharge at a very low rate, are not affected by the vibration of a bike, do not overheat like lithium ion, and last forever. I’ve used Shorai batteries in 3 bikes and each one lasted 10+ years. One was in a bike I rarely rode and started the bike right up after 4 months with no maintenance charging. When my R18 original battery gives up the ghost I’m putting in a Shorai.

I’m glad that someone has had good luck. I’m just sharing my experiences here.
I look at it like choosing between a Toyota and Ford. Some people have good luck with their Fords but just about everyone has good luck with their Toyotas.
It’s simply comes down to the averages and Lithium batteries and at the bottom of the reliability chart right now. Hopefully it changes soon because they definitely have done advantages.

Some info on reliability of LiFePo4 batteries:

The issue is not the number of cycles or wearing out. On all three lithium batteries that failed, it was the BOS component that failed.

I was addressing your statement that lithium batteries are at the bottom of the reliability list. All 3 of your BOS failures on lithium ion batteries? LiFePo4 batteries do not have a high failure rate for the BOS or any other component, you must just be very unlucky.

Yes, they were all Lithium iron batteries, one Shorei an two NOCO.
Batteries are what they are. But when one of these goes out it’s done. There is no charging it and no bringing it back. You cannot even start it with a jump pack. To me that’s simply unacceptable.
 
Wow, you must have extremely bad luck. I’ve had 3 Shorais and each one has lasted over 10 years. I hope you find something that works for you.
 
LiFePo4 BMS failures are usually caused by overcharging. (Less often undercharging or operating in extreme temperatures) Did you try resetting the BMS (sometimes works)? If that doesn’t work You can replace a BMS much cheaper than replacing a battery.

Well, at least they’re replacing it. I hope it’s only batteries you have such bad luck with, that’s some bad battery juju.
The FTR is currently in storage. But when the battery arrives I’m going to run over and install it make sure it’s not another turd.
