I doubt anyone is interested, infact someone said the other-

I doubt anyone is interested, in fact someone said the other day in another place that I had been chased away from here. Nothing is further from the truth. This week is the first time in a year I have had time to breath and relax for me.

As some know I care for a lady with Asperger etc and help boaters, I visit boaters on average twice to three days a week and have gone from one end of the country to the other to see boaters in trouble plus have in the last year installed approximately £50,000 worth of LiFePO4 systems, BTW that is the trade price which is what the boater pays. It been a lovely year I have not made a penny which was the target, cannot bear HMRC, and there are a few boaters out there who are happier with their electrics and understand them a bit more than when I arrived..

Tomorrow a new year starts and Thursday or Friday a 450Ah LiFePO4 system arrives to be installed on a boat on a boat next week.

If you want the LiFePO4 to last and give of their best life etc, don't subject them to high charge levels, it shortens their lives and don't full charge them, both things the BMSs do not cope with or control. Keep their rate of charge to about 50A per 100Ah, OK it lengthens the the charging time, but does not stress the batteries by causing a temperature rise of 20C/30C  On one boat I visited the charge level was so high the BMS was stopping charging as it was taking the batteries over the maximum 50C. Not good for the batteries nor the alternators.  I am aware of several alternator being burnt out by being worked to hard when kept at high level of charge for the alternator for over an hour or so.

Somewhere I think someone has posted that LiFePO4 stay at the same level of the charge and do not reduce the level of charge as the batteries charge. Up to a few weeks ago I would not have argued about it, but a system had a funny fault in the control system and the only way to check the fault was truly cleared was to recharge the batteries from 50% discharged. The rate of charge was reducing all the way through the charging cycle. Not anywhere near the rate it reduces with lead acid and at approximately 98% charged was still giving 25A into a 300A bank. Now I will hopefully be able to repeat the exercise on larger banks and see if it was something else that was affecting the current drop. Maybe the Starter battery which later was proved to be faulty, so needs more actual with big banks.

Look after yourselves you crazy lovely lot
