HUM Posted February 23, 2021 Posted February 23, 2021 Hello I am considering installing a Lifepo battery in my GSX 1100E, my controller is a NipponDenso 32800-45210 can I operate a lifepo abtterie with this controller, or does the controller bring too high voltage, i.e. over 14.4 volts ? someone has experience Cheers Uli Quote
Arttu Posted February 23, 2021 Posted February 23, 2021 (edited) Basically you can use LiFePo batteries with the same regulator than normal lead acid battery. Maximum voltage is pretty much the same for both. However, LiFePo is less tolerant for both under and over voltages. Anything below 13V won't charge it at all and over voltage will destroy it faster than a lead acid battery. And one additional note for anyone reading this: Make sure you don't mix LiFePo batteries with LiPo/LiIon batteries. Latter ones have different voltage range and they can be dangerous if charged incorrectly! Edited February 23, 2021 by Arttu Quote
Dezza Posted February 23, 2021 Posted February 23, 2021 (edited) All aircooled engines have charging systems designed sometime in the early Permian period. Even if all the components are changed and wiring renewed IMHO it's just asking for trouble using an Li battery. The oil cooled bikes have a more modern charging system so using an Li battery is probably less likely to end up in a small scale re-enactment of a scene from a low budget action movie .

gorbys Posted February 24, 2021 Posted February 24, 2021 I swapped to a lithium specific regulator from rick's motorsport to be a little on the safe side. Quote
Joseph Posted February 25, 2021 Posted February 25, 2021 (edited) What i suggest in this topic here : https://oldskoolsuzuki.info/forums/topic/15598-new-regrec/ Works great with a lithium battery Edited February 25, 2021 by Joseph Quote
