2015 RXV Battery Replacement

[wingnut2000]

Right now I have 6 trojan 8 volts probably around 3 years old. I have tapped and drilled 2 battery post on the 2 main batteries already to because the batteries bulged the other ones almost off. The SOC digital meter drops to 60 and 70% fairly quick after riding so I am thinking its about time for a new set but i havent been pleased with the trojans. Honestly not sure something the cart has caused the weak performance or my expectations were too high. What batteries would you recommend? A drop in lithium or Crown batteries or something else?

I did some load test going up an incline the other day and it read

At rest I showed 49 v on my hand held meter
going about 5mph it dropped to 44v mid ways up then about 42v at the top
at rest on top 48.5 volts.

I am very partial to the Crown agm ...maintenance free....bms worry free.
From what I have been reading for the most part new lithium or modified
to lithium don't come close to the range I get from Crown agm 6 crv 260ah.
True the cycle recharge life said to be shorter...but not necessarily so
with a good charger and charging at the end of each "duty cycle"...long
life is expected.

I use a Dual Pro ...Eagle Pro 4818i bulk, absorption, float and will equalize
balance charge...can leave on charge when you want to store during the winter.

My 6v x 8 agm very 630 lbs heavy...yet my ICON I40 hits 29mph and will
hit 25 going up hill....

I run 15 to 25 miles and my cart never slows down...with 98-99% soc still
available..

The issues with lithium from what I read range from bms issues, reliability
price issues, a lack of local reps....and though lithium boasts of long warranties...after some years in service...will there really be any warranty support...?

Should you choose Crown agms the Eagle Pro is a must and set up for the Crown agm..I had a very very bad experience with the Lester Summitt 2
650w charger ..I did use the 22259 profile...but it managed to cook those
batteries. My dealer came through for me and credited them for a new
pack.

There are some success stories with lithium...but not enough for me
as of yet

Best wishes deciding..

Happy cartin'

FWIW I'm going to buy US 8VH ATB for my six 8 volt conversion when I can locate the needed battery tray. From what I've gleaned here this US battery has the highest amp hour rating for any FLA 8 volt. $170 each at the nearest dealer.

Thanks. I'm going to get a front basket like that one day. Looks like some nice hill country where your at. I hunted deer in Newark, Ohio few years back.

I replaced my Trojans with U S batteries. Had slightly better specs and slightly less cost.
Two years in happy with them.
