Hi mark, Darren is bringing that battery with him today, can you please give him the old one thanks.

Cheers Justin

Hi mark, don't use it again mate, I'll replace it, they've actually changed the case on the 4s packs to a stronger more durable case, I'll put 1 aside for you and have it charged on the Friday night before the long weekend, Darren will bring it out and collect the old one.

Cheers Justin
