This GRAUPNER ULTRAMAT Charger is capable of Charging & Balancing all cells up to 12s in power. The Ultramat 18 charger is used by the TRAMPA team for charging all of our decks that use Zippy Cells for power. The charger comes with a UK or EURO Plug for wall plug in connection, XT90 Jack leads & 2x 7 pin adaptor plates which allow balancer cable connections from 2x batteries from 1s to 6s using JST Connectors.... As the Graupner is our suggested charger for the Zippy cells this charger is somehow incorporated into the design of our Battery Boxes so using this charger is nice easy to connect, it is reasonably fast to charge whilst it balances (looking after) your cells at the same time and you dont need to remove anything in order to charge as the cells are all snugly secured away in one of the amazing Carbon fiber boxes, which as it so happens have been designed special for this style of charger & easy charging... :-)
12s power is the perfect amount of power to be pushed through any of the TRAMPA Electronic products (12s should only be applied when using the very special TRAMPA VESC6 speed controller). When 12s power is pumped into the VESC6 you will be able to experience the kind of riding performance everybody is talking about. Do not push more power than 12s into the VESC6. Using a XT90 Battery harness cable kit to connect 2x 6s batteries together will double the battery power resulting with a 12s Battery WITHOUT Any soldering or Welding!!
So as you now know, to achieve 12s power requires a minimum of 2x 6s Batteries (it could be more cells if you were custom making your battery or if you were achieving 12s from 6x 2s, 4x 3s or 3x 4s cells as they can all be harnessed together to make 12s power... but then you will most likely need an additional balancer cable harness or more chargers to charge/balance each cell individually if you want speedy charging), so for efficiency & simplicity we base our 12s power on the use of 2x 6s cells as generally speaking there are many good priced nice performing chargers put there which also have the ability to balance your cells to prevent failiure of the cell, already on the market are capable of charging up to 2x 6 cells at any 1 time,
which maximizes efficiency which in turn means less chargers & (of course if you are making a custom battery you will need a BMS complicated system & Soldering skills) so you either need 2x 6s Battery chargers or 1x charger that is powerful or large enough to charge 2x 6s batteries at the same time to reduce charging times & this GRAUPNER ULTRAMMAT 18 charger is the charger TRAMPA is currently recommending of using capable of charging 2x 6s cells at any 1 time, so if you are running 12s made up from 2x 6s batteries, using this graupner charger you can charge both 6s cells at the same time.... :-)
As well as suggesting our customers find the best performance through using custom cells to make custom battery packs & BMS (Battery management systems), this all gets a little complicated for the majority of our customers, so for ease of supply & speed of installation as plugging in the 6s Cells means no welding or anything messy like that, as well as achieving excellent performance & fabulous range, TRAMPA is strongly encouraging the use of the ZIPPY Compact 6200mAh 6s 40c Lipo Pack with XT90 connectors in on any of the Boards in TRAMPAs range that use either the 12s BEAST BOX or 12s2p MONSTER BOX, as these high power 6s Cells not ony fit perfectly into these custom made Carbon Fiber boxes, but the lids & sides of the Boxes have been CNC'd allowing the wiring loom to flow beautifully inside, further enabling the battery balancer cables to poke out of the rear or sides of the box, whislt most importantly allowing the Charging XT90 connectors to push tightly into & fit perfectly into the precision cut holes in the lid, which are secured int position by the use of s simple ZIPTIE, allowing for simple but very strong KEY connection for turning your board on or off & allowing a really easy plug n play to charge both 6s cells at 1 time when using this Grauper charger
sit perfectly, further allowing Lug holes for the XT90 Connectors to fit into & be secured by a simple ziptie
