Other thoughts: Why is Lawrence replacing his 12V aux battery? If I remember correctly, he traded in his old gen Leaf for a newer (2017?) 30kWh Leaf. That would only make his 12V aux batt 3 years old, which should last from 4 to 6 years. If Lawrence is having 12V battery issues, it may not be the battery (perhaps the dc-to-dc charging circuit, etc.). If so, no matter what 12V battery (chemistry), he'll still have problems. ?So, why do you want to replace your 12V battery, Lawrence? (I ask evdl members with more li-ion purchasng experience to weigh in here) Paul had a point: only some li-ion batteries I found have internal circuitry to handle the voltage & charging differences between li-ion & PbSO4. Adapting the battery cable connectons makes me think targeting motorcycle battery markets is more appropriate. In researching this, I got less web hits with 15Ah, and more with on 14Ah 12V searches. Also, a curious use of lead-acid equivilent Ah ratings (?) See label on https://cdn11.bigcommerce.com/s-xnv61jmj9h/images/stencil/1280x1280/attribute_rule_images/18723_source_1581637298.jpg Does this mean because li-ion as less internal resistance, the Ah capacity rating for li-ion can be rated differently, but equal to a lead-acid battery with a higher rating? (this can cause confusion ... i.e.: is that featherweight 1Ah battery is equal to a 4Ah lead-acid?). Here are soe of the searches and links I found that might help Lawrence in his quest: https://www.google.com/search?q=12v+15ah+lithium+motorcycle+battery+-acid+-agm Shorai battery was mentioned on https://www.speakev.com/threads/anyone-changed-the-standard-12v-battery-to-lithium.6620/ ?Who are they? https://shoraipower.com/about-us Founded in 2010 in Sunnyvale (in silicn-valley), Calif., Shorai Inc. has quickly become the world’s principal producer of prismatic cell, lithium iron phosphate power sports batteries.
