The built in protection circuit looks desirable to prevent over-charging.
Thanks
Bought one for our 2015 Honda Grom when the stock one went bad. Purchased on March 31, 2018; haven't had a problem. This was before the built in charging circuit. Not sure if we've ever had it on a charger, but if we have it would have been the Battery Tender lead/lithium charger that came with it.
Shorai batteries can be maintained with a RC charger that can do Li-Fe and can use a balancing lead. I use that arrangement for the Shorai batteries I have as I somehow ended up with extras and need to maintain them.
The charger I use is a 'Hobby King C3', the lead I purchased for balancing is 'Associated Reedy 4s Balance Lead ASC27230'.
If you go with the new Battery Tender line let me know how it works out.
I have one of these chargers: https://www.batterytender.com/Battery-Tender-12V-800mA-Selectable-Lead-Acid-Lithium-Battery-Charger_7
I bought one of the early Anti-Gravity batteries several years ago. It failed early without much usage. The replacement has proven to be more durable. They are expensive though.
man that is some fancy ass battery tech. :cheers:
LI batteries don't tolerate over-charging well. I think the problems begin around 14.7 volts.
