I've bought three batteries from these guys and they have some great value for money options for electric scooters etc. My purchase was for my over volted razor scooter. 12v 9ah SLA Batt AU$29.00 delivered. I installed 3 of these 3 months ago, which I charge and use up to 3 times a day on average and they haven't missed a beat thx again batteriesdirect.com.au regards Jay (2 of these are a perfect fit/replacement for razor E200 and E300 models)
