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, for example that the Sur Ron Ultra Bee does not use a circuit breaker and relies on the BMS alone).\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications for Talaria MX\u003cspan\u003e5\u003c\/span\u003e Upgrade Battery 72v 55Ah 9C\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cdiv\u003eWeight 19.2KG\u003c\/div\u003e\n\u003cdiv\u003eCells Samsung 50S 21700 (220).\u003c\/div\u003e\n\u003cdiv\u003eBMS set at 400 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 stainless steel sealed box to give maximum protection and insulation.\u003c\/div\u003e\n\u003cdiv\u003ePure copper sheet for connections (not Nickle sheet)\u003c\/div\u003e\n\u003cdiv\u003eBluetooth BMS giving individual series condition with balanced charging.
