    Need Advice on Equalization and Battery SG (unusual)

    It seems to me.....like that batteries refuse to take a charge. They show the proper voltages (which means little) but the SG (which means EVERYTHING) shows a totally different story. Can you slave in 2 other batteries (known good batteries) to see how they perform?

    Whats a good 48v battery charger

    I bought a 48VDC 120 amp for emergency situation. It worked fine when i tested it out. I run it with a 9500 WATT harbor freight predator. I think the Honda Wannabe is the weak link here....

    Weak cell issue solved!

    my bad......i never said you made you own cables......but when i look online i see the R/C chargers and they say cables sold separately. I haven't seen any 1 gauge cables.....thats all. I have to make a lot of my own cables out of 4/0 welding cable. Nothing wrong with making your own wiring.

    Weak cell issue solved!

    do you make these 1 gauge cables yourself or do they come with the charger? Is the output voltage adjustable in .1 volt increments? i have to find one that runs on 120vac and outputs 2.6vdc at or near 100 amps for a PB battery

    Weak cell issue solved!

    Mine Hindle runs continuously at 2.6 VDC outputting 13 amps. (it is rated at 10 amps, but will output 13). Ideally i'd like a charger that outputs 100 amps at 2.5 / 2.6 volts. What is the gauge of the wiring that carries 2.6 vdc 100 amps to the battery?

    Luke, I owe you an apology and more than that, I am impressed. How low does your battery normally discharge. Is it normally discharged 70% with a 30% charge left.

    Forklift (Industrial Battery) consistently weak cell, problem solved

    About your question on how often I boost charge the weak cell. In the winter my battery bank doesn't see a lot of sun so it doesn't charge properly every day. I think this erratic charging takes a toll on the weak cell more than the others. So in the winter, I boost charge every month or...

    Forklift (Industrial Battery) consistently weak cell, problem solved

    Hi Ralo. It maxs out at 2.6 VDC. at 10amps (although the meter sometimes shows 13 amp). I have a 1500A/H battery I am trying to boost charge with this charger soooo the charger is overmatched, but it works for me. For me, being off i grid, my battery usually charges every day. In...

    Weak cell issue solved!

    I can charge all 24 cells of a 48VDC,1500 A/H FLA battery at 61-63 vdc OR I can charge a single 2 volt cell at 2.5 to 2.6 vdc. I can and do, do both, Tell me specifically, what i am doing wrong? Tell me how I don't know how to EQ a battery? Tell me how to its wiser to use a "R/C hobby...

    Weak cell issue solved!

    BTW. It doesn't take a rocket scientist or 25 years experience to charge a battery, whether its a 2 volt cell or a battery made up of 24 individual 2 volt cells. It take the right equipment and a limited amount of knowledge. My post was simply to let people know that there is an alternative to...

    Weak cell issue solved!

    Thanks for the input. I am wanting a 120 vac input (not 240) and 2.6 vdc output, Until i get, one ill settle for the 10amp battery charger I currently have as it works

    Id love 30 or 40 amps............the 10 amp charger works, but with a 1500A/H system, it is severely overmatched

    Better yet. just tell me the error in my ways. I have a 48 volt battery made up of 24 individual 2 volt cells. 23 of the cells charge just fine. One cell is delinquent........and it lags in Voltage and SG. Please explain how I am to EQ the battery. I know I can apply 61-63 volts and...

    Forklift (Industrial Battery) consistently weak cell, problem solved

    I EQ at 62.5 volts for 2 hrs. (48 volt system) and my batteries never go above 90 f. Also, my batteries are in my basement in a vented containment vessel environment (around 55-65 degrees in the winter, 75-85 in summer) They never get cold..so to speak. I used to EQ more often but...

    Hi Luke, I run electrical heaters. I did today. It was severe clear and my solar array made 66kwh. 30 kWh went to recharge the batteries and 36 went to the 4 ea 1500 watt heaters and a 6000 watt dryer. Normally i use 26KWH daily (about a constant 1100 watt draw). without dryer or...

    Need Advice on Equalization and Battery SG (unusual)

    I have an electric dryer and and a electric oven and electric stove (go ahead and shoot me...i deserve it). I say that because trying to charge the battery daily in the winter....and running the dryer...and oven and stove, can be be very challenging. Are you trying to run a whole house?

    Need Advice on Equalization and Battery SG (unusual)

    OK.....your system is equal to 130 AH at 48 volts. My system is over 10 times the capacity. That isn't meant as a dig,,,,,just a fact. What are you running with this system. I run a 2500 square foot house.. with a wood pellet stove and a couple of propane heaters (very low wattage to heat...

    Forklift (Industrial Battery) consistently weak cell, problem solved

    Ralo, where are you located? I use it when the SG difference reaches 3 points. As a matter of fact i am using the 2.6 vdc charger right now. How many A/H is your battery?

    Need Advice on Equalization and Battery SG (unusual)

    Luke, Were the batteries used? What is the A/H rating of your 24 volt system? How deep of a discharge do your batteries normally experience daily? To be accurate I have a 1500A/H 48 volt solar forklift battery that are discharged about 25% daily (still 75% left in battery). I absorb...

    Here is a Enersys HUP battery brochure, HUP is another forklift battery adapted to solar. I wish i could have afforded HUP batteries. Anyway, HUP has good literature about their battery. BBI.....not so much.

    Forklift (Industrial Battery) consistently weak cell, problem solved

    Sorry, I equalize at 62.5 volts for 1.5-3.0 hrs, Depending on what the SG at the start of EQing. As for Bulk......I take whatever mother nature will give me. I have a 14400 watt array, but on a sunny day, 12000 watts is a more realistic bulk charge........12000 watts is 218 AMPs at 55...

    Actually there is nothing to get. A battery charger IS a purpose built power supply designed to charge batteries. I never thought of charging 1 cell, with the power provided from the other 23, but that is what is happening here. Essentially, I am robbing peter to pay paul. Peter was...
