Allison Transmission leak

My 2000 Safari Sahara has a couple of small leaks in the bolts. One on a drain bolt and another one on the bolts on the front. Suggestions? Just try to tighten them up a little?!App4bDOKyF9rhpdm2RoynmqQQz86aA?e=smgJnq height=600 width=800!App4bDOKyF9rhpdlr_3oxZcPblIVig?e=2tIrZX height=800 width=600

RE: 2004 Cat C7 Charging LifePo4 battery bank

Not an expert but there have been prior posts that typically alternators will not sustian their maximum ratings without damage which is basically what you want with that amount of Ah. But not sure what you mean by 1200A - Are you planning for 1200 Ah? Suggest you get the model number and contact the mfg. Well, by 1200 amps I meant 1200 usable amps. 6 280 amps batteries. 15kw in the 12v system. I also have 28kw in a 48V system to run all the 110-220 with a split phase. This 12v battery bank will be for storing the solar and running the 12V side of the house. If needed, I can run 110V through the inverter (which I might be upgrading to a low frequency inverter so I can run ACs with the 12v batteries). I have a 6kw inverter generator that I can use to recharge both banks at a 90% efficiency, if I ever need it, wich I don{t believe I ever will. I am getting rid of my diesel generator. I am done with the smell, noise, maintenance and ineficiency. With what I get from selling the generators I can do all of this and more. Now I have to find a way to control the flow from the alternator or install a timer on the batteries so the charge intermitently.

RE: LiFePO4 - SOK or Renogy.

My only concern would be temp protection, but you mentioned that is not an issue. If that is the case, I bought LifePo4 280Amp cells on Wish shipping from US $270. I am sure you can access it from Canada. There is also cells in Amazon. They are all the same cells you can find in SOK and the other batteries. Throw in a BMS and make your own battery. I am making a 1200 amps temp protected BT conected for under $1500

RE: 2004 Cat C7 Charging LifePo4 battery bank

Map40, I wish I could help more, but I am currently still in the research phase for a client. There are available DC-DC chargers that both create the correct final voltage for charging LiFePo4 batteries and limit the charge current drawn from the source. It is a single unit. There also should be a BMS Battery Management System with the Li unit to keep it from hurting itself or others. As said, this is a study in process on my part. Matt Thanks for the reply Matt. I got that part covered. The batteries are managed by their own BMS which can charge them dirvectly from the alternator feed. All of that works and so far I have 340 amps installed and they work great. My concern is: Will the alternator take the workload? The old Lead acid setup was 300 amps to recharge in the worst case, but when you talk about 1200 amps, the alternator will NEVER rest. Wil it last?

2004 Cat C7 Charging LifePo4 battery bank

I am upgrading my battery bank to a hell of a lot of capacity (Around 1200 amps). I know that if this was a gasser, the alternator will die young if it has to charge the bank. How good is the alternator in the Caterpillar? Will it take sustain maximun capacity constant? Otherwise I need to find a way to regulate power or connect and disconnect the banlk ontermitently. Thanks!

RE: Wire gauge for a 200 ft run on 30 amps or 50 amps?

:)3% for voltage drop. Hopefully, Old Biscuit is indicating copper wire and not aluminum. Direct burial or are you going to put in conduit? :S I was going to have the GHana Dancing Pallbearers to do the burial :)

RE: Wire gauge for a 200 ft run on 30 amps or 50 amps?

advice. Thank you for that, I cringe whenever I see this and it reminds me of the state of education in America. No, no, don't go blaming the state of education in America. Here is the problem: I speak 6 languages and use them frequently, so my phone and computer do not know what I am writing and the autocorrect wants to commit suicide every time I chat with somebody different. You should see it when I go from Spanish to Cantonese...

RE: Wire gauge for a 200 ft run on 30 amps or 50 amps?

3% Max Voltage drop for that 200' run Otherwise you will have Low Voltage any time the supply voltage drops below 115V 50A #1AWG 30A #3AWG Do NOT scrimp on the wire size........... Thanks and thanks for the advise!

RE: Wire gauge for a 200 ft run on 30 amps or 50 amps?

Thanks! What would be an acceptable voltage drop? 5%?

Wire gauge for a 200 ft run on 30 amps or 50 amps?

Anybody has a good calculator for wire gauge? I need to do a wire run of 200ft buried wire. I can do 50amps or 30amps. Any advise will be greatly appreciated!
