Batteries ALL SECTIONS
BATTERIES:
In the interest of safety, any battery pack(s) carried on a model car must be able to be disconnected quickly without the use of tools in an emergency. Direct soldering is not allowed. All Lithium based drive batteries must be in a ‘closed’ LiPo sack when being charged or discharged. This applies to any discharging procedures, except during a race or when using organiser supplied resistors to correct voltage. LiPo sack is defined as a receptacle designed for the purpose of charging LiPo/LiFe batteries and is of a suitable construction so as to contain a LiPo/LiFe fire. Sacks must be obtained from a recognised supplier to the UK RC industry.
The BRCA will not approve any Lithium battery for use at BRCA sanctioned events that exceeds 4S in a single unit. Charging of Lithium based batteries (LiPo, LiFe etc.) at all events and in all Sections must be strictly in accordance with the procedures detailed in BRCA Electric Board rules. These procedures are covered in Electric Board rules 3.6, 3.7, 3.8, 3.10.
‘Over’ Charging of Lithium based batteries is potentially dangerous and maximum charge cut-off voltages must be strictly adhered to. The maximum charge cut-off is based on 4.20v per cell (LiPo), 3.70v per cell (LiFe) for cells connected in series. Therefore the maximum charge cut-off voltages allowed are: 1S - 4.20v (LiPo), 3.70v (LiFe) 2S - 8.40v (LiPo), 7.40v (LiFe) 4S - 16.80v (LiPo), 14.80v (LiFe) Effective from 1st. April 2017: ALL Lithium based ‘drive’ batteries, over 20wh, used in ALL Sections must have a hard, protective case that completely envelopes the cell(s). The case should be made from ABS or a similar strength material. The two halves of the case must be factory sealed in a way that any attempt to open the case will destroy the case. The only opening in the case that is allowed is for exit wires or ‘pin type’ connectors. General Rules 2026 V1 2026 BRCA Members Handbook General & Constitution Rules Page 2 of 7 Lithium based batteries that are used for powering receivers, servos or other devices, that have a capacity exceeding 10Wh., should preferably have a ‘hard case’ (as detailed above). If a ‘soft-cased’ battery is used that is over 10Wh. then it must be protected from accidental damage. This protection can be an equally strong ‘casing’ or ‘box’ within the design of the car that encloses the battery, or other form of protective shielding that will totally enclose the battery and protect it from accidental damage during racing or maintenance. Any Lithium battery not having the original manufacturers label that shows the energy capacity in Wh. should not be allowed.
