The Vengeance V2 – MaleVolentlyPowerful!

Sur Ron Battery 72v 20s 3600Wh 50Ah Vengeance V2 40Kw. 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. Extended warranty!

Cells

There are 220 cells in this battery and all have internal resistance. 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.

Power

Sur 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. We have spent several months testing and evaluating the cell we are using and so confident we are extending our cell warranty to 18 months for this battery.

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.

Connectors

The main Sur Ron Battery to controller connectors we use are two QS8 connectors with 6 AWG going direct into the controller and a second smaller 8 AWG QS8 connector with a free high power loom that goes via the red trip.  We use two sets to share “parallel” the power. This reduces heat, transfers load more efficiently and keeps the connectors from overheating.

Domestic Electrics

This 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).

Fitting

The 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).

For 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:https://electroncycles.com/product/two-into-one-converter-qs8-supra-d6-talaria-oem-any-combination-available/

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”.  Always charge your battery in a safe place and never unsupervised.
