Batteries – Lithium Based (LiPo) Packs.
2.7 With 2009 being the first year that the BRCA (EB) has officially formulated rules and approval lists for Lithium based (LiPo) batteries, the submission date for samples is extended. Any new rechargeable LiPo battery has to be received by the BRCA Electric Board Homologation Officer by the 31st Jan. 2009. No fee is payable.

2.8 Subject to 2.1 & 2.7 (above), the new battery will be included on the homologation list for the following year, and can be legally used at BRCA sanctioned events from the 1st April of that following year. It follows that any new battery becoming available during a calendar year can only be used from the 1st April in the subsequent year. i.e. No new batteries will be homologated during the calendar year or racing season. For 2009, the option of a 3.7v LiPo pack may be included with specifications to be confirmed, and a ‘rolling’ homologation list for the first year.

Lithium Based (LiPo) Battery Packs.
The storage, charging and use of Lithium based batteries (LiPo) can give rise to serious safety implications. The BRCA will publish guidelines for the safe use of these batteries on the BRCA website. It is imperative that the guidelines are studied and adhered to.
3.3 Lithium based (LiPo) battery packs must have a hard, protective case that completely envelopes the cell(s). The case should be made from ABS or a similar 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 the exit of wires.
3.4 For 7.4v Packs: The maximum case sizes allowed are as follows: -
Length: 139.0mm.
Width: 47.0mm. (The max. width includes any side exit wires).
Height: 23.5mm. (In addition, chassis location protrusions are allowed)

Saddle-Pack cells are allowed, and must comply with the above width and height dimensions.
Saddle-Pack cells must have a combined length dimension of 139.0mm max when placed end to end.
For 3.7v Packs: The maximum case sizes allowed are as follows :-
Length: 93.0 mm
Width: 47.0 mm
Height: 20.0 mm
