This is the big power daddy of our Dominator Battery. Smaller (range wise only) but able to pump out EXTREME power. We wanted to make a slightly more cost effective battery with almost identical performance with only a small sacrifice to range, but a huge price drop of around £500 GBP.

The more resistance, the more heat they produce, until they start to damage. So with this low resistance, they are able to supply enormous amounts of power without over heating. We wanted to make a slightly more cost effective battery with almost identical performance with only a small sacrifice to range, but a huge price drop of around £500 GBP.\u003c\/p\u003e\n\u003ch3\u003ePower\u003c\/h3\u003e\n\u003cp\u003eSur Ron Battery 72v 20s 3600Wh 50Ah Vengeance V2 40Kw power as limited by the 550A (peak\/burst for 10 seconds) by the Ant 550 BMS.

This reduces heat, transfers load more efficiently and keeps the connectors from overheating.\u003c\/p\u003e\n\u003ch3\u003eDomestic Electrics\u003c\/h3\u003e\n\u003cp\u003eThis means all your bike accessories are still powered. Some believe that not using the circuit breaker direct to the controller removes the safety of the circuit breaker. However, all our batteries have a full working BMS. Any power shorts or irregular current and the BMS shuts down.  This is much more sensitive and accurate than a mechanical breaker (you may note that the Sur Ron Ultra Bee does not use a circuit breaker and relies on the BMS alone).\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecifications Sur Ron Battery\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eSame physical size as our 72v Dominator Battery\u003c\/p\u003e\n\u003cdiv\u003eWeight 19.2KG\u003c\/div\u003e\n\u003cdiv\u003eCells 21700 (220) Molicel p45B equivalent\u003c\/div\u003e\n\u003cdiv\u003eBMS set at 550 Amps Peak.  Full battery protection including over discharge (shorts) over heating etc.\u003c\/div\u003e\n\u003cdiv\u003eEach cell with additional individual wrapping for added protection.\u003c\/div\u003e\n\u003cdiv\u003eAdditional layers of fibre board, Kapton tape, heat shrink.\u003c\/div\u003e\n\u003cdiv\u003eStainless steel 316 grade sealed casing\/exoskeleton with internal\/external powder coated to give maximum protection and insulation.\u003c\/div\u003e\n\u003cdiv\u003ePure copper sheet connections.\u003c\/div\u003e\n\u003cdiv\u003eBluetooth BMS giving individual series condition with balanced charging (We do not recommend altering our settings as may invalidate your warranty).\u003c\/div\u003e\n\u003cdiv\u003eAn integrated cord handle for lowering the battery in and out.\u003c\/div\u003e\n\u003cdiv\u003eCharging port via an XT60 connector.\u003c\/div\u003e\n\u003cdiv\u003eBattery lid hinge extenders for Sur Ron.\u003c\/div\u003e\n\u003cdiv\u003eHeight 375mm to top of lid not including handles\u003c\/div\u003e\n\u003ch3\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe battery uses two sets of discharge cables. One to fit the original bikes connector (for Talaria we supply an adapter so it can also fit a Sur Ron too). The second goes to an additional cable that we provide that is fixed direct to the controller. This enables the power to be fed “In Parallel” increasing the electrical flow, reducing resistance and reducing harmful heat. It shares the power delivery and takes the strain away from the original loom. These must be connected in a specific order (simple instructions supplied).\u003c\/p\u003e\n\u003cp\u003eFor those using a Torp Controller, Torp do not like direct power to the controller via your second cable.  You can either not use the additional power cable we supply (we do not like to remove these as often buyers transfer batteries to another bike) or, if you are worried about your Torp warranty, you can request one of our 2 into 1 convertors in the checkout notes.  Details of the adapter can be found here:\u003ca href=\"https:\/\/electroncycles.com\/product\/two-into-one-converter-qs8-supra-d6-talaria-oem-any-combination-available\/\"\u003ehttps:\/\/electroncycles.com\/product\/two-into-one-converter-qs8-supra-d6-talaria-oem-any-combination-available\/\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eCell Specifications\u003c\/h3\u003e\n\u003cdiv\u003eSize: 21700\u003cbr\u003eChemistry: INR\u003cbr\u003eNominal Capacity: 4500mAh\u003cbr\u003eNominal Voltage: 3.6V\u003cbr\u003eDischarge: 36A Continuous per cell Max 45A\u003cbr\u003ePositive: Flat\/Button Top\/Tabs (please select)\u003cbr\u003eRechargeable: Yes\u003cbr\u003eDimensions: 21.1mm x 70.4mm\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eConnecting To Bike\u003c\/h3\u003e\n\u003cp\u003eWhen connecting the battery to the bike and to avoid a spark, turn the red trip switch on the bike to off.
