Whichh charger does expertpower recommend (for 10 ah battery)? if battery's built-in bms offers 'complete protection', how can sla charger damage it?

Hello again! I wanted to clarify the differences in charging a sealed lead acid battery (SLA) vs the LiFePO4 battery, and why the BMS can't protect a LiFePO4 from SLA charging damage. First, let's touch on the charging characteristics as both batteries have unique charging processes that take full advantage of their chemistries thus maximizing lifespan and performance! - SLA: Typical lead acid batteries have a full charge voltage of 13.8 volts or 2.3V per cell (6 cells) SLA cells have the unique property of balancing themselves out. As such, lead acid chargers just need to provide a voltage higher than battery's voltage to bring the battery to its maximum state of charge (13.8V). - SLA chargers: Most lead acid smart chargers provide 3 stages of charging: bulk, absorption, and float-- each with their own respective function. (Keep the float stage in mind, I’ll get back to this in a bit) (Float charging keeps a lead acid battery at 100% state of charge as they have high self-discharge rates) Voltages are unique to each type of battery as their chemistries have differing energy densities. - LiFePO4: LiFePO4's voltage sits at 14.6V or 3.65V per cell (4 cells). An SLA charger will read 13.8V from this battery when discharged and think it is fully charged when in it is not, leading to disappointing capacity. Some chargers may even bypass the bulk and absorption stages and keep the battery float charging which basically means it won’t even charge since the charger thinks the battery is 100%! Keep in mind, some SLA smart chargers perform equalization of the battery's cells which will damage the LiFePO4's cells as well! - LiFePO4 chargers: Chargers for LiFePO4 perform 2 stages called "Constant Current/Constant Voltage" (CC/CV). A preset current charges the battery up to a preset voltage then the current lowers as soon as it hits that preset voltage up until it reaches a 100% state of charge (14.6V). The BMS can't protect a LiFePO4 battery from an SLA charger because keeping a LiFePO4 battery at 100% through float charging isn't necessarily harmful in the short-term, but in the long term it will speed up aging of the cells as their activity is constantly stimulated due to the extra power coming from the SLA charger. This extra stimulation leads to polarization (buildup of material where the electrodes make contact with the electrolyte) and electrolyte decay. It's absolutely necessary to use the correct charging algorithm (CC/CV ; 14.4V) as SLA smart chargers WILL NEVER fully charge a LiFePO4 battery or charge it ADEQUATELY enough to provide maximum lifespan and efficiency. Too much charging voltage for too long and you risk breaking down LiFePO4's internal electrolyte, too much charging current for too long and you shorten the lifespan of the cells.

Hello The charger is sold separately. Each LiFePO4 battery has its own maximum continuous charge current as follows: 12V10Ah - 5A 12V20 - 10A 12V50 - 25A 12V100 - 50A 12V200 - 50A We do carry our own chargers here: https://www.amazon.com/dp/B082LV7RKL?ref=myi_title_dp If you have any more questions, feel free to reach out to us at (562)630-3002 or support@expertpower.us

Please explain the 10 year warranty. Prorated, I pay shipping both ways?

Thank you for your inquiry. These batteries come with a 2-year warranty; the 10-year estimated life expectancy is based on the 7000 cycles this batteries are capable of.

can i use this to my 2016 bmw r1200r motorcycle?

Hello, This is not a starter battery so it cannot be used to crank the engine but if you are using it for auxiliary there should be no issues although you'll wanna keep in mind how much current flows through the auxiliary. Feel free to reach out to us at 562-630-3002 or support@expertpower.us so we may assist you further!
