Battery Life Saver test

crash test dummy

as some of you know i am going to be installing a BLS system, Battery Life Saver, on my cart for testing and evaluation

i received the BLS from BatteyZombie for this test with the understanding i would give an unbiased opinion of the results

so here we go ...
the BLS i got was the BLS36A, for 36v carts that are charged often, the BLS36N has an automatic low voltage cut off for carts that are not used daily

all BLS systems use power form the battery pack to work , the 36a comes with an on/off switch if desired to cut power to the unit
here is what i got
BLS36A retail $139


WHATS IN THE BOX
BLS36a unit
on/off switch
12 page owners manual
BLS sticker



BLS36A comes per-wired with 36" of red and black wire and 5/8" ring connectors
switch is heavy duty on/off



so now its time to install it

but first i am going to get readings from cart and post them as a starting point

we are in a rain delay

Looks you're being very thorough Crash- great! Have fun and happy buggying!

. . . are you starting with "good" batteries or trying to rejuvenate "marginal" batteries that BLS claims it can bring back to 100%?

crash test dummy

I am starting with Trojan T-605 batteries date code K0 which = 11/2010



the pack voltage is 38.2v after full charge and 10hrs rest



i tested all batteries and recorded results average 6.3v



i then load tested each battery all tested in the good but on the low side



finally i tested water in batteries all had a good reading but low @ 1.275 specific gravity



will be checking weekly i have recorded all results in a journal
next the install of the BLS

i miss spoke in video i hook red first and NEGATIVE last ..DOH !!!
ez install



so now we wait and see

I'll be watching crash. I've wondered about these units.

i would say they are "good" ...the 38.2 reading is at 100% charge and the Specific Gravity of 1.275 is good also -- i have good run times and GPS @ 11.5mph on flat smooth road

I posted this in another string and moved it here after ordering the BLS 48N:
I will install this unit and track the results over time as well.
After reading this thread and with the camping season finally upon us I decided it was time to do a good check of the batteries on the cart we bought last fall, here is the disturbing data I found. 06 Precedent hooked to a Power Drive 2 charger most all winter. Checked water levels every 6 weeks but did not have a volt meter hooked up. Voltage checked from the Red ( positive ) and Black with White strip wire that would go to a volt meter.
First it seems odd to me that I read 35.2 VDC (prior to switching the run tow switch to run). Switched to run I read 49.7 VDC I cleaned all the cables and restarted the charger. After the charger shut off with no bleed down time of the float voltage was at 51.2 ,After 12 hrs 50.4 Here are the individual battery readings and hydrometer cell readings prior to restarting the charger.
5/12/2013
Bat #1 12.51 VDC cells 1.250 1.260 1.275 1.276 1.250 1.200
Bat #2 12.69 VDC cells 1.260 1.250 1.262 1.262 1.275 1.280
Bat #3 12.52 VDC cells 1.280 1.280 1.270 1.275 1.200 1.200
Bat #4 12.58 VDC cells 1.300 1.270 1.230 1.270 1.250 1.175
So I am assuming that these batteries are not the good batteries that the seller claimed they were. With these reading however what could I try to do to get some use out of these until such time as I can afford to replace them.
Ordered BLS-48N 5/13/2013

thats great !! a 36v and a 48v test

Will be glad to provide the results also how well this works with the low battery shut off.
