Sur Ron 72v 55Ah Dominator EVO Battery 15 kW Atom Controller

Description

Did you ever get sick of seeing mods just skyrocket in price? We wanted to supply a tough robust reliable controller and battery option that wouldn’t break the bank (too much). A kit that gives the standard bike with the standard motor, real usable performance without all the bells and whistles and extra costs that comes with stuff you really don’t need or want. Does a REAL rider need wheelie control? Does a real rider need a big display to say how much power he is using (should be looking at the trail) or a gazillion different power modes? We think not.

The controller bolts straight onto your bike and uses the original LBX display that gives Eco and Sport mode. The only difference is sport mode with a 72v battery will hit 70+mph and lift the front wheel any time you want (3 times power over standard).

The controller does have a very basic app, which is primarily used for the original set up: motor tune – throttle tune and battery set up. Its a bit fiddly so if you don’t want to do it, we will! We can remote onto your bike free of charge via a remote session (via your mobile device with you controlling and your phone). Think of the kit like this, the same set up you had a before (no gimmicks), just loads MORE power.

A standard Sur Ron has around 1500Wh of range. The Dominator EVO is 3960Wh. That’s over DOUBLE the range!!!

For the Dominator EVO battery, just like its other brothers in the Electron Cycles battery List, we have used the best, super tough, 316 marine grade stainless steel casing, powder coated inside and out, it has the big ANT BMS, two QS8 6AWG cables and pure copper sheet connections. Supplied with a high power bike side loom and fused high power cable.

We don’t make a huge amount of money out of these, but all the same same, buying as a Kit (battery and controller) we have shaved the price down even further.

Description

Exoskeleton /Casing

We have upgraded the casing to marine grade 316 stainless steel, so absolutely no rust issues here! Super tough and powder coated inside and out. Designed not to rust in salty sea water.

Connectors

The main Sur Ron battery to controller and battery to bike connectors we use are a 2 x  QS8 on a heavy duty 6 AWG cable. This allows higher power flow and less resistance than a standard cable and connector. We supply a free upgraded high power loom with the battery.

We supply the bike side power loom to replace the original power loom that goes through the circuit break, and an additional second fused cable that runs up beside the breaker. Their simple to fit, just add the two red positive lugs on to the controllers positive terminals (piggy back.) Then fix the two negative black lugs of the two looms, to the negative terminals on the controller (piggy back)

Voltmeter

This Sur Ron Battery does not have an integrated voltmeter.  We supply a voltmeter that nestles in your battery lid.

Domestic Electrics

With our replacement high power bike side loom, all your bike accessories are still powered. Some believe that not using the circuit breaker on the second fused loom, that goes direct to the controller, removes the safety of the circuit breaker. However, all our batteries have a full working BMS and the non circuit breaker loom is protected by the inline fuse we include. Any power shorts or irregular current and the BMS shuts down or the fuse blows.  This is much more sensitive and accurate than a mechanical breaker (you may note, for example that the Sur Ron Ultra Bee does not use a circuit breaker and relies on the BMS alone).

Fitting

Fit the high power cable we provide to directly replace the OEM cable that came with the bike. We supply the battery lid spacer and aluminium hinges. The second fused loom we supply, goes direct to the controller and piggy backs the first loom.

Battery Charging

First time charging is VERY important. Always connect the charger to the battery with the charger powered up at the mains first. This will stop a “Connection Spark”. The battery needs a “Balance Charge” on first charge. Please charge for 12 hours first time.  Always charge your battery in a safe place and never unsupervised.

Charger Included

This Battery will not work with a Standard Sur Ron Controller

Regen & High Power Set Ups

Running regen on high power set ups can cause damage to both the controller and your battery. The motor can give massive power spikes if the motor is quickly turned into a generator from wheel spin and re-engagement (wheelies, jumps, hitting pot holes hard etc.). The battery is designed to give high power and BMS mosfets struggle to suddenly have such a large reverse current fed into them.

We have seen well known third party controllers give damaging current as the controllers become unreliable under reverse polarity caused by their regen settings. “Motor Off” and thumb regen should be set low or better still turned off. If you are running extreme power like 20+ KW (250A, regen must be turned off. Failure to do so may invalidate your warranty.
