I can make you battery cables, generator cords, any size, any gauge cords, any battery cords ends, see my projects pictures! Can charge batteries with my truck very fast, I call it transfer power.
I have built a charging system that can charge 6 AGM 12 volt batteries and charge the batteries full, running the roof air conditioner 15000 BTU and running the fridge 400 watts at the same time pulling 2,300 watts off the batteries on my 5th wheel RV going down the road, running on a 3,000 watt pure sure wave inverter, will charge the batteries in about 15 min. and have power to spare, I will have more pictures for you soon.You can call me at anytime. 616-392-3037
Lonny regardless how many amps you have available to charge batteries, you are limited by the design of the battery - dictated by the batteries internal resistance.
For a standard Flooded Lead Acid battery (something you will probably run into the most) "The maximum recommended rate is C/5 (a charge rate in amps of one-fifth the overall battery capacity in amp-hours), but only when the cells are between 10 and 85 percent state of charge (SOC). After the cells reach 85 percent SOC, then a C/10 is the maximum. After cells reach 95 percent SOC, between C/20 and C/15 is recommended." www.homepower.com/articles/solar-electricity/equipment-products/ask-experts-battery-charging-rates
Trying to force too much current into the batteries too fast will result in a surface charge, where the batteries appear full but are not. This can even damage your customer's batteries through overheating and warping the plates. Be sure and research the various battery designs and their charge rate capabilities carefully if you want to start a business as you suggest, so you don't end up being blamed for damaging someone's expensive battery bank. The reason smart chargers were invented was to charge batteries at an optimal rate, filling them completely without damage. Good luck to you in your business venture.

I have talked to Odyssey batteries technical service, they said they charge the batteries with 320 amps in 15 minutes, they also said I was doing everything right. I would not do this on a wet cell battery, it would boil the cells in the batteries, I would not recommended this on a wet cell battery, my batteries are 4 years old and still working good.

As a spectator on this subject, I will watch with great interest. I am constrained to point out that Chip's referenced link is from 2006, aeons ago in todays rapidly advancing battery technology space. Those guidelines could well be still valid today in certain circumstances. Lonney's idea may well have viable science behind it or practical documentable evidence, he's promised videos so I look forward to seeing them. Not saying either is right, but it is very interesting. Can't wait to hear other perspectives from other battery systems "experts" on here.
On the surface, Lonney, it looks very interesting. Your other projects look well executed also.

Oh, I'm charging 6 batteries, you have to divide the batteries into 6 that means 6x30 amps, so 30 amps per battery is how it works, the batteries will only take what they want.

AGMs have very little internal resistance, especially the spiral wound types like the Optima, Hawker Genesis, etc. I have an Optima and a Hawker Cyclon (a helper battery for a high current electric supercharger) in my car. They can be charged 5 times faster than a typical FLA battery (c/2 - c/3). Lithium batteries can also be charged very rapidly and efficiently, however they are sensitive to charging at low temperatures and overcharging. 30 amps on a 100 amp/hr battery is c/3.3 which is perfectly fine for an AGM, but too high for an FLA.
Some types of batteries can be charged much more quickly than others. I'm just advising to know what type of battery you are dealing with before deciding on a charge profile (charge rate and time for different phases of the charge cycle). If the battery gets hot (warm is normal) during charging it's a good sign that the internal resistance is too high for the charge rate. Modern charge controllers monitor battery temperature and adjust the charge rate to the optimal level automatically, preventing damage to the battery bank from overheating. Just tell it what type of battery you have and let it do the job it was programmed for - simple as pie.

When I was charging the batteries, battery cable or battery never reached over 100 degrees with a Laser temperature gauge, AGMs never need to charge over 15 volts, they come up very fast, when they reach 13 volts after they sit for sometime, about 2 hours, after that I have not seen any changes, they are fully charged, you see batteries charge faster under load, the batteries see a load and the voltage regulator thinks the batteries are not charged so you get a faster charge all the way up, the regulator will not stop charging until the batteries are charged, up, up and away 100%, I watch the amp gauge on the negative wire start to go down, power goes in the red and comes out the black, you check the negative wire for your amps, it's about 5 amps more different from the red, it's all about the testing. I scare myself what I find. My secret is out now, don't tell anybody!!!!
