    We want to increase the leisure battery capacity. Its was a new van in December. The battery has only been used on EHU for one week and several weekends.

    We have a Varta Hobby 90AH leisure battery and think our cheapest option is to buy another one to double the capacity. Its under a bench in the dinette so there is plenty of room but will need a new tray and clamps.

    I understand about keeping battery age and capacity the same - is our battery still new enough to do this and if we do it will the charger cope?

    We are also thinking about installing a battery monitor like the NASA BM 1 to monitor usage and battery status. Is this a good idea?

    We want to do more wild camping and hope to run the standard van bits and pieces and TV (12v) and Sky (on small inverter) and also charge laptop intermittently. All our lights are now LEDs. In the longer term we will need to consider something like B2B charger or solar but at the moment will be relying on driving and occasional EHU.

    All comments and advice welcome - thanks in anticipation! :thumb:

    You have a perfect plan, just do it.

    I would have expected a vent from battery to outside.

    We get a good 3 days out of one battery but no sky box.

    Hi

    We fitted the NASA BM-1 monitor and it is brilliant. Gives peace of mind as you know exactly what is going on with your leisure battery's. :thumb:

    I just wish there was a suitable one for the chassis battery (they say the NASA is not suitable). :Sad:

    I felt like that until we got back from Carmarthen and found that my Leisure batt. would not run anything off the 350W inverter-even though the BM-1 was saying 105% charged and showing in excess of 14v. :cry:
    I took the inverter back to Sterling Power and it checked out ok-M/H is now going in on Wed to be checked over-will post results on here.
