Have you amended your charging voltages when you changed from AGM to Lead Acid ?

With AGM  the float charge should be between 2.25 and 2.30V/cell (summer temperatures may require lower voltages). Whilst flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell), 

 

Permitted development rights of navigation authorities :
Town and Country Planning (General Permitted Development) Order 1995
British Waterways  Schedule 2 Part 17 (Development by Statutory Undertakers),  Classes B, C and D

 

Permitted development rights such as those in Part 2 (Minor Operations), Part 3 (Changes of Use) and Part 4 (Temporary Buildings and Uses). Part 4 includes the ‘28 day rule’ under which land may be used for any purpose for not more than 28 days in any calendar year, subject to certain limitations.  

 

You are of course correct but my understanding was that as "A Statutory Undertaker" they had additional/different GPD rights.

.

Yes I think they do in order to carry out necessary works.

Either way C&RT are exceeding their powers & are contravening Planning Law by allowing 5 month winter mooring permits for 'residential use' of the canal bankside.

There are one million answers to the question.

 

The one and only true answer is that given by C&RT (IN WRITING)  when you ask them.

Actually The Town and Country Planning Act 1990 specifies 28 days in any Calendar year so BWML aren't quite there yet. The issue is that it will need a few test cases to determine whether residential use of a leisure mooring is enough of a change of use for any planning authority to take action. There was a case on the Driffield Canal, sorry don't have the case number, which found that the use of two moorings as residential did not sufficiently change the use of the 70 berth marina to require planning permission.

I do not understand the logic in this. The time it takes to recharge a bank or battery from a given source is dependant upon how many Ahs were taken out so given the same charging regime the bank size should make little difference to how easy they are to keep fully charged. That is unless you decide to go longer between charges but then it is your use that has caused the problem, not the bank size.

 

Nick's figure of having a bank size of about four times the discharge between charging periods is a good guide but if you are talking about 440 Ah or 550 Ah (say) then remember the lower the discharge as a fraction of capacity the greater the banks effective capacity courtesy of Mr P. In that situation I would always go for a slightly larger bank.

Just the thoughts of a simpleton.

If you use 100 amps from a 200 amp bank, the SOC is at about 50%

If you use 100 amps from a 400 amp bank, the SOC is about 75%

You still need to replace 100 amps

A bank at 50% SOC will accept a higher charge rate than a bank at 75%, so, assuming using the same charging method a smaller bank will in fact charge quicker than a larger bank.

Right or wrong ?
