Once again Amptron have come to the party with their great advice and speedy service! This is my 3rd purchase of a 12V 100Ah LiFePO4 battery, because I believe they’re simply the best battery on the market. Have never had a problem with any of them, from the 1st one in the 4WD to the last 2 I installed in my last two caravans. Great value for money; great battery performance.
