SOLD Victron BMV700 + 3 Duracell DL115 Batteries

[Reto]

I have just been upgraded by the wonderful team at VanBitz to Lithium Ion leisure batteries and needed a new BMV712 monitor so now have a 2 year old (as new) BMV700 with all cables and shunt for sale. Open to offers but VB suggest £70-75.00
I can obviously arrange to post this at cost.

I also have 3 x Duracell DL115 deep cycle Leisure batteries (spec here https://www.batterycharged.co.uk/duracell-dl115-12v-115ah-leisure-1244733.html ) They are 2 years old and again in very good condition but obviously far too heavy to ship so would need to be collected from me here in Malvern. Again open to any reasonable offer either with Victron BMV700 or separately.

Why the new monitor?

Why the new monitor?

Going under Victron's advise, the 702 and 712 monitors detect what is called "Middle Voltage". This gives a more accurate read of both large battery banks and also Li Batteries (being multi-celled).
Please see quotation from Victron below;
" Midpoint voltage monitoring (BMV-702/712 only) This feature, which is often used in industry to monitor large and expensive battery banks, is now for the first time made available at a low cost, to monitor any battery bank.
A battery bank consists of a string of series connected cells. The midpoint voltage is the voltage halfway along the string. Ideally, the midpoint voltage would be exactly half of the total voltage. In practice, however, deviations will be seen, that depend on many factors such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacities and much more.
Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or cell. Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery. Please consult the BMV manual for more information ".

Hi Nick. Thanks for providing the answer! I know you did explain all that to me at the time but I would never have been able to cover off so informatively. Must sit down and read the manual one off these days!!
By the way - delighted with the fantastic job you guys did ..as ever ..thanks again.
