I live off grid in Upstate NY. I have a 14400KW solar array, 4x Midnight solar charge controllers, 2x8048 Outback radians and a (1500 A/H, 6000 lbs,) 48 volt BBI "forklift" battery. and a 30KW Isuzu diesel generator I was having issues with one cell always being 6 points lower (SG 1.22 vs...

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...

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...

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.

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....

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?

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...

BTW.....one of us looks like a total moron and 1 of us doesn't. I'll take my chances!!!

Hello there, I have a summer time absorb voltage and a winter absorb voltage. My winter time absorb voltage is 58.8 vdc for 3 hrs my summertime absorb voltage is 58.4 for 2 hours. I float at 54 volts in the summer and 55 in the winter. My batteries rarely go under 75% depth of charge...

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...

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...

Luke.....is your total system only 260A/H @ 24VDC? Only 2 12volt batteries?

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?

https://www.forklift-battery-charger.com or buy a used single phase one on eBay

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...

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?

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.

I live off grid and have a 48 volt, 1500 amp hours battery. It is comprised of 4 each, 12 volt, 1500 A/H forklift batteries, in series. One of the 4 is giving me issues and i was thinking of changing it out. I am looking at installing a 12 volt HUP battery but the HUP is 1600 A/H. My...

your battery is a 1275 AH battery.....isnt it? 85 X 15???? If that is the case....127.5 amp to 255 amps

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...

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.

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...

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.....lets compare apple and apples. Please bear with me. My home, no matter the size, has a energy star fridge and freezer and LED lights. I have a pellet stove that draws 120 watts and propane heaters that draw 26 watts. I have a heat pump type hot water heater. Even If i dont use...

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...

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

Couldn't agree with ya more.

if anyone knows where I can get a power supply that puts out 30-40 amps at 2.6 vdc please send a link

School me!
