[QUOTE="WTM, post: 5685577, member: 6230"] i wouldnt do it, even to the gls10 and i surely wouldnt to an echomap mfd. the transient (not homeless people) from those batteries can be enough to burnout the first LDO regulator in the power section. garmin and lowrance doesnt recommend it but humminbird said the helix can take the transient spike. i kind of doubt it since they use the same type circuit but hey they will repair it for you for about $400. garmin has also said that theyve already had to repair several from folks using these batteries. ive seen a couple burned out as well. folks listen to this stuff on youtube and social media and take it as gospel. usually from someone that posts the spec page out of the manual without very little knowledge of electronics. it also happens with installers and lithium battery salemen. they claim that 16v batteries will use less power and run cooler than 12v. this is pretty much nonsense. run 16v to an input of a 10v output LDO and it gets you 6v (3/7w) heat dissipation of over 100 degrees of extra heat dissipation. a lot of heat for an LDO thats not heatsinked and will lead to premature failure. its another reason minn kota issues a warning with LFP batteries and only running their motors at 85%. ive seen these motors get so hot on 36v motors that it peels the paint off them.
