This is great Spud. I had done some research of batteries for the RX3 when the times comes. Here is what I found:

Yuasa YTZ12S-DS Battery
Positive on the Left, Negative on the Right
6.00 x 3.44 x 4.38
11Ah
210CCA
8.1 pounds

Shorai LFX14A1-BS12 Battery
High end replacement. Requires their battery charger
5.83 x 2.63 x 4.13
14Ah
210 CCA
1.83 pounds

Bikemaster DLFP-14ZS
Polarity is correct. Need lithium trickle charger
5.82 x 3.43 x 3.7
5Ah
CCA 250
2.4 pounds

Battery Tender BTL14A240C Lithium Iron Phosphate Battery
Polarity is correct. Need lithium trickle charger
5.27 x 2.55 x 3.62
14Ah
CCA 240
1.76 pounds


Battery Tender 022-0198LI Lithium Junior Charger for Lithium Iron Phosphate Batteries Green

Do you believe that the 14Ah Lithium batteries would NOT be able to keep up with a heavily farkled RX3 like mine which has the following:

300 watt stator

160 watts used for normal operation

140 watts available
Standard headlight is 35W. Genssi uses 76W = 36W difference
Volt/temp gauge = 5W as a guess
2 x 2.1A @ 5V USB chargers = 10.5W each = 21W
Hyperlites = 3W
2 x Offroad spot lights = 10W each = 20W
SpeedoDRD = 5W as a guess
Glove liners = 15.6W on high
Jacket liner = 84W on high

36+5+21+3+20+5+15.6+84=189.6W used for accessories

160+189.6=349.6W


According to this my stator and battery which are stock should not be keeping up but they do. I've never had it run the battery down even on LONG riding days of 10+ hours and then repeating that the next and next days with out a trickle charger to top off.


Take care!
Joe
