LiFePO4 Batteries

Does anyone have experience charging these with a battery tender plus? I've got a new K2 10ah battery and considering a specific charger.

What indications does the battery tender give? What's a typical time to charge?

Jeff,

The LFP batteries, while they can be charged with SLA chargers, are better charged by a dedicated LFP charger. The reason for this is they need to charge up to 14.6 volts to get a 100% charge. Most SLA chargers will give only 13.75 volts and this leaves the LFP battery around 80% charged and this pretty much defeats the purpose of buying the higher capacity LFP battery.

I have LFP chargers for $30 (see the address for my webpage in my previous post).

A multi chemistry charger with firmware that is upgradable to accommodate changing battery technology is a better way to go. CellPro (and other knockoffs) has several chargers that will safely and accurately charge LiFePO4 batteries among many others with one charger.

I have used a Cellpro multi 4s charger to charge my Shorai lithium iron battery which does not have a battery management system for quite a while. It will also charge a lead acid, nimh, nicad, lipo and others.

You will be able to set the charge rate, monitor the health of the cells, balance the cells (still important for a LiFePO4).

Thanks guys
