    Default Bluenova two or one

    Want to replace the 2 deep cycles in my Cheetah with either 1 x 218ah or 2 x 108ah. Any thing I should keep in mind?

    I have one 200ah Sunsol battery. You will be happy and much cheaper than Blue Nova. Contact Byron at Sunsol solar.

    Perhaps just the length of the 218ah battery, it is listed @ 552mm.

    Is your battery charger lithium ready?

    With two batteries you can,

    1. Leave one at home, to save weight, if two are not needed for a short trip.

    2. Have a backup if one fails on a trip.

    3. Do bush welding by connecting them in series (24v).

    4. Place them at different spots in the vehicle for better weight distribution.

    Don't know what you pack under the bed in your Cheetah, but in general 2x 100 Ah sized batteries fit that space much better, since you can put them side by side, then it's much like the footprint of a case of beer.
    A single bigger battery like a 200 Ah actually wastes a lot of space since it's like 2x 100 Ah batteries next to each other in their length, so it basically takes up half of that compartment if you have it positioned front to rear of the van. If you can find a bigger battery which can fit in side to side of the van it can work, but I doubt it since the wheel arch is in the way.

    With the 108 Ah Blue Nova's you can't interface the BMS's of the batteries together, so the 2 going out of balance might be a problem, however I have no experience here, so in terms of this a single bigger battery might be better again, then you don't have to worry about balance, you don't have to worry about parallel cabling or fuses etc.

    Maybe also look at the Blue Nova 13V 2K mini HP, it's only 154 Ah though.

    120A/H @15kg vs 108A/H @50kg. Keeps 2 fridges running happily. Fits behind the backseat.Click image for larger version.

    Lifepo4 cells with box home made to fit behind the Cruisers backseat. This is only a testpack/prototype I slapped together. Once the rattletest is done and passed, the first production set will be built, but without battery poles but rather with Anderson plugs as well as a digital battery monitor.

    Hi BruceHun,

    Do you perhaps have images of the SunSol-E battery installed and feedback?

    I will take pics and post.BL installed it for me. All i can say so far is that it is a brilliant battery. Check under BL mods.

    I can't help but go back to this little saying from my days in the army "two is one and one is none" quite often having a redundancy plan is of more value than efficiency.

    I do travel with a blue nova 82ah in my battery box as well as my car has a second battery.

    same can go for battery charger, water pump, mppt etc. do you carry those as spare as they are also only one?

    I have a Flexopower 444 as my back up which has battery charger and MPPT built in, I am thinking about a water pump but the Fortuner only has 70k on the clock.

    Similar to me. I meant water pump for camping trailer though.

    Sorry I made the assumption on the water pump but it seems that we agree on the principle. If there's a potential fatal flaw in your set up think of a back up plan.
