The build list is like a dream: Reliance RS50 (242 cells used) cells. These are the very best and most uptodate, highest performaing cells on the market.  Made with pure copper sheet connections. The Hybrid BMS is an ANT 550 BMS (250A\/550A). The exoskeleton case is made from stainless steel 316.\u003c\/p\u003e\n\u003ch3\u003eCells\u003c\/h3\u003e\n\u003cp\u003eThere are 242 cells in this battery and they all have internal resistance. The more resistance, the more heat they produce, until they start to damage. The Reliance RS500 is classed as the worlds premier cell for low resistance for a high power density (Ah). So with this low resistance, they are able to supply enormous amounts of power without over heating.\u003c\/p\u003e\n\u003ch3\u003ePower\u003c\/h3\u003e\n\u003cp\u003eSur Ron Battery ZEUS \u003cspan\u003eEVO \u003c\/span\u003e81.4v 55Ah 45Kw as limited by the 550A (peak\/burst) 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\u003eWith 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).\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eFit the high power cable we provide to directly replace the OEM cable that came with the bike.

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.

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.\u003c\/p\u003e\n\u003cp\u003eWe 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. \u003cstrong\u003eFailure to do so may invalidate your warranty.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBike Not Included\u003c\/strong\u003e\u003c\/p\u003e","brand":"Go Off Road Barnsley","offers":[{"title":"Default Title","offer_id":57631347835253,"sku":null,"price":3499.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/0953\/3678\/files\/zeusbattery.jpg?v=1749802455","url":"https:\/\/go-off-roadbarnsley.co.uk\/products\/electron-cycles-sur-ron-battery-zeus-evo-81-4v-22s-55ah-4450wh-45kw","provider":"Go Off Road Barnsley","version":"1.0","type":"link"}
