Sur Ron Battery 81.4v 22s REALLY ROCKS!

Why? Because a electric motor spins so many times per volts. More volts, more spins (RPM), more top speed. But here is the geeky and cool bit (literally). Amps create heat, so the less amps you use, the cooler stuff runs (heat kills electrical components as the heat literally melts soldered contacts internally, insulation burns off and glues melt). When you increase voltage, you need less amps to get the same amount of power. For example, a 72v battery running at 200 Amps gives 14400 watts but if you use a 81.4v battery at 200 amps, you get 16200Watts!!! So if you want to run cooler then drop your amps back down to 176A and your still hitting the same power. Or just keep the amps the same and go waaaayyyyy faster !!!!!!!!! Also, field weakening be turned down, once again.

This battery has the same power density of its  brother the 72v Dominator. They are extremely similar batteries, just reconfigured. The Dominator has a touch more brute force, while this battery is more refined.

This is a Sur Ron Battery 81.4v 22s 4070Wh 50Ah Trojan for 21Kw High Power Long range Battery, si  capable of peak 21kW power (450A peak discharge until cut off on mosfet temp protection).

20kW continuous at 250A discharge run continuous load until cut off on mosfet temp protection.

Our premium battery just got better!!! We swapped out the brilliant Molicel P42A and upgraded to one of the most long range cells money can buy: The class leading Samsung 50S 21700 cylindrical steel jacketed cells (no puffy cheap pouches here). These cells give almost 20% more range and can supply high amp draw, your controllers require.

We then swapped out our standard 330A BMS for a special order 400A BMS. This means these batteries can now continuously supply 250 amps and burst to 400A. This new super high output power can now handle bikes with the extra powerful: Sotion, EBMX and KO motors; yet keep the standard OEM Sur Ron motor running for huge long rides.

We then upgraded the casing from stainless steel 304 to marine grade 316 so absolutely no rust issues here! Super tough and powder coated inside and out.

The main Sur Ron Battery to controller connectors we use are the same type as used by Sur Ron but we use two sets to share “parallel” the power. This reduces heat, transfers load more efficiently and keeps the connectors from overheating.

The Sur Ron Battery 81.4v 22s 4070Wh 50Ah Trojan for 21Kw High Power Long range. The cells are genuine branded cells specifically designed for high output discharge and sustained high drain. Other inferior cells (pouch) used in cheaper packs simply can’t deliver like these.

Our last and most recent upgrade is to supply one direct set of discharge cables to the controller via a high capacity QS8 connector using very large 6 AWG cables (this reduces internal resistance and heat build up) and a separate second set of discharge cables using the original 8 AWG cable via a Supra D6 connector to the OEM loom via circuit breaker. 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.  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. However these must be connected in a correct order (simple instructions supplied).

Torp do not like direct power to the controller (your second cable), so please just do not use the additional power cable. We do not like to remove these as often buyers transfer batteries to another bike.

Same physical size as our 72v Dominator Battery

When connecting the battery to the bike and to avoid a spark, turn the red trip switch on the bike to off. Connect the older original power cable and then turn the red trip to on. Then connect the new power leads. Removing the battery has no special order.

Charging: First time charging is VERY important. Always connect the charger to the battery with the charger powered up from the mains. This will stop a “Connection Spark”. The battery needs a “Balance Charge” on first charge. Please charge for 12 hours first time.

Charger NOT included

Please note, Lithium batteries are considered hazardous and due care and attention should be taken. Although these cells are in wide use, and professionally manufactured in a purpose built factory; because of the power of the battery, we strongly recommend that precautions are taken. We do not recommend charging inside the family home and charging should be supervised. We take no responsibility for misuse. These batteries are thoroughly tested (full discharge and charge cycles at the manufacturing stage and also pre-delivery). These are not DIY or amateur built devices.

This will not work with the original Sur Ron Standard Controller

* Warranty, due to the nature of use of these devices (off road) manufacturer warranty is limited to 12 months from date of purchase of  the battery. Any damage the result of water ingress, alteration, may void warranty. Failure comply with the correct connection procedure, may lead to damaged to the BMS and connection plugs and will not be covered by warranty. This includes shortening of cables and changing connectors. It is the owners responsibility to proof against water ingress and not use in unacceptable very wet conditions, or use direct water from hose/washers.
Warranties are not transferable. We do not warranty second hand goods.
We reserve the right to slightly modify or change this product without notice.
