Hi I bought these new SLA's called Ritar, I’ve been riding them for a good 3 mths now and they seem to just give out the power needed to be compatible the golden motors controller and hub IC needs.
It says they have a mulriple gel technology, they are marked as AGM however I take it they use a little more gel in these.
I googled mulrippile a little time back and got one hit, It said something about filling the spaces with gel making the batteries last longer.
I bought 3X20 rt series and have only triggered LVC once a couple of weeks ago against high wind, on a steep hll with a trailer load of stuff after about 30km riding pedals the bike got me up the hill and home around the corner with no troubles with a lil pedals .
I got it home and tested the batts 20 seconds after riding and they all read 12.33v with about .02v difference in balance.
I thought so highly of these I bought 6 X 24 ah batts that weigh over 7+kg in the smaller mountable package, 4x12 would be too heavy though. Good for 36v applications.
The 20ah rt series would go well in 48v applications if you’re are a smaller build person,
The spec sheet reads 200 amp max current draw and internal resistance of the rt 20ah is 16 ohm.
http://www.ritarpower.com/products.aspx?catid=19&pcatid=RT12240EV listed under EV series, The 24ah batts are gel based and have this mulriple technology in them have 240 amp max current draw a internal resistance of 10 ohm,
so put a fan on your charger..

I estimate I’ve done probably 300 cycles already with the smaller RT12200 20 ah batts I'm using now and they go go go.~~~~~~~?
They retail equally with other brands with older design and seem to do the trick thus far..
I'll keep anyone interested informed of their usage history...
