battery advice for a acfe racer

[queenmonkey]

Hi guys i'm currently building a GS850 cafe racer. It now has a TR style racing seat. I've moved most of the electrics and have put a YTX12A- BS dry charged battery under the hump. Is that battery going to be ok? It was new and i was going to fit it to my Aprilia RSV but i sold it. I've seen one of those Shorai batterys for sale which is the right size but 18amp. I'm not very electrically minded - any advice would be appreciated as to keep the 12amp on or upgrade to the (lighter) 18amp Shorai.

The Shorai come in different amp hour ratings, and are much smaller which for racing you woudl be hard pressed to find an easier and cheaper way to drop 6-8 lbs of weight.

The amp-hour rating is mainly how much capacity the battery has, they are all still 12V batteries. There is a differnce in Cold Cranking Amps (CCA) between the two batteries below (210 v.s .130 amps)So for short starts you probably will not be able to tell the difference (unless your engine is much higher compression than stock). It just that as higher amp hours the battery will crank for longer before the cranking starts to slow from using up the avaliable charge.

This one easily cranked my 1166 CR=10.25:1 GS1100ED CCA=210amps, 730 grams, 14amp-hrs

This one has fewer cold cranking amps CCA=135, 560 grams, 9 amp-hrs

The LFX14L2-BS12 is quite small compared to stock so for the extra 170 grams it is alot more capacity.
