The main problem with all the current cells out at current like the trackpower cells is that they arn't factory sealed so will still be illegal! See the brca lipo rules for 09 below c&p'd from the brca web
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
3.6 The battery pack shall have leads extending from the case for the positive and
negative electrical connections using wire of adequate size to handle discharge rates
acceptable to racing applications. Alternatively, the case shall have internal
connection points for these wires clearly marked positive and negative so the user
can apply the lead wires. It is strongly advised that the link wire for Saddle Pack cells
utilises a plug which will separate with any undue force.
3.7 The case must have the original suppliers label intact, stating the rated voltage
and the pack capacity. Maximum capacity is 5,500 mah. The Brand name/logo shall
be easily readable.
