Lester summit 2 over volt fault

[Malachi]

My charger is giving an over voltage fault. I have it on profile 22252. This is what the profile selector chose for me on the app. I know US batteries normally have a higher full voltage than others. Has anyone else experienced this?

What is your battery pack voltage?

With my 1st cart a Star Sirius 48v ac I had ordered Crown crv 6v 220ah.
My cart came with a Lester Summitt II 650 w. The profile for this was the 22259 according to the Lester app.. The Lester Summit II would remain
on the phase 2 charging 67-68 volt endlessly cycling thru this portion
of the charging cycle...finally it fried my agms. Fortunately my dealer
came through for me and credited me back. I ordered the Crown crv 260ah
agms along with a Dual Pro Model Eagle Pro 4818i charger with a specific profile for my then new agms.

It only took 4 months for Lester to fry my 1st set of agms... I do not
trust Lester chargers...

My 2nd set of Crown agms are now 1 year 3 months of use. In combination
with the Eagle Pro 4818i my agms are great. Even after almost 30 miles
of riding they don't come anywhere near fading or gasping. They get put
on charge nightly every night and a log kept.

I did upload my Lester's charge log to Lester...hopefully they have corrected
their profile's algorithm.

My Eagle Pro 4818i can be left charging even when I am away on a trip.
This charger will bulk, absorption, finishing stage and if plugged in for
1 month will automatically perform balance-equalize charge stages.

I thank God for His help with this!!!

The Lesters are throw away if they fail ..the Eagle Pro is field serviceable.

This has been my adventure trail ...and share this to hopefully shed some
light with regards to your post..

Wish you well Malachi

Happy cartin'

My batteries are us2200. I have 8 6 volt 232 ah. It pulls up the correct batteries in the app for the charger. It just goes to over voltage fault after a while. It charged my 6 T875s just fine.

Thanks Malachi...my Lester started messing up with identical symptoms
as you mentioned earlier then went south from there taking out my first
set of agms....just keep a watchful eye...keep a charging log ....

Just a reminder the profile maybe correct for particular battery...but the
profile algorithm maybe inaccurate with respect to the actual battery
requirments.

Hopefully things will turn out ok ...

Happy cartin'
