Just came across a long thread on
Yesa LiFePO4 batteries, the same make as those on ebay.
Haven't read it fully yet, just sharing the information
.
A 24V 10Ah is 230 x 85 x 65mm and weighs 3kg, so the 36V 10Ah 'Ezee size' one should be around 4.5kg? 3A Charger weighs about 500g.
Also, this is from the Yesa ebay Q&A:

Q: how much for a 48v battery and charger. thanks. 01-Sep-07
A: 48V 10AH LiMn2O4 , USD500, 48V 15AH LiMn2O4 USD540. 48V 15AH LIFePO4 USD680, we do suggest people choose LiMn2O4 pack when under 15AH. Cheaper but also good as LiFePO4. LiMn2O4 is not suitable for pack above 15AH .
