Using the ULTRA POWER Charger It is possible to charge & balance 2x Batteries packs up to 12s in size at the same time...
SO for example if you have 2x Electric Boards in your collection, (lucky boy) if they are both running a single 12s pack (i.e. 2x 6s 22000 mAh HRB Cells in the MONSTER Box or 6x 2s HRB 10, 12 or 16000mAh in the Underboard Battery Tray or the BEAST box's) then you can fast charge & balance 2 x Boards at the same time or if you only have 1x Board but you are running 2x 12s packs (i.e. 4x Zippie compact cells fit directly into the Monster Box using a Graupner charger you can only charge 1x 12s pack at a time so you will need double the time to charge 2x 12s packs if you have 4x Zippies cells unless you purchase another Graupner charger so you can then charge both cell packs at the same time - if this is the option you have selected, then it is also possible to boost the speed of the charge of your 2x Graupner chargers by placing a Booster charger before them) then this is the deluxe charge for you.
This charger is terribly expensive but it is everything the 2x Graupner chargers with a Booster box option tries to be. It can charge incredibly fast up to 15A, it has an internal booster with amp adjustment for charging & Balancing all kinds of cells. The best part about this charger is that you simply plug it in & it knows the cells you have, Its possible to mix up the balance cable connections when plugging in for the first time but it alerts you to this &you simply swap over the cables & it knows... (best practice is to mark the balance cables so you know in the future which one goes into which port without having to exchange them each time for guessing wrongly lol) simply select the amount of Amp charge you wish to put into it by pressing the select button (a low 2A charge will balance your batteries beautifully but will take a long time to do, where as turning the charger up to 15A will give you a fast boosted charge, which is great if the weather is amazing & you cant get enough riding on that day but its not good practice to fast charge your cells all of the time, so only fast charge when you don't have time to wait for a nice balance charger, but selecting a low to mid power option on a regular basis will keep your cells in the best operating conditions),
The ULTRA POWER Charger is not supplied as standard with Balance extension cables or XT90 Cables to plug into your batteries. We have acquired some Balance extension cables and have also made some nice 30cm TRAMPA Silicon charge cables with XT90 connectors on to make charging with the ULTRA POWER Charger to be really easy & fiddle free. The Cable kit is available at a discounted price when purchased with the ultra power charger, however the extension cables can be purchased anywhere on the internet and its not rocket science to make your own extension cables if you have the time to do this & will of course save you a few quid in the mean time.
