Great news for shopping fans! There's a freebie available right now: [Humsienk] Humsienk Spring Sale, 12v LifePO4 battery from $107/kWh. This one costs you absolutely nothing. What's the deal? Wasn't in the market quite yet, but gathering info and found these quite cheap for LifePO4 lithium iron phosphate batteries. I've put some of their specs on to a spreadsheet (same as the attached image) for those that want to compare dimensions etc. Use code HSCA5 for 5% off the sale prices. Seems to be Free Shipping as well (excluding territories). Says "5-7 day domestic shipping" so maybe they have a CDN warehouse? 5 year warranty, but no idea how those are handled with something so heavy. Only mentions return shipping is covered if there's a defect found within the first 30 days.
