if you get 8 years out of it well worth it...i just spend 1/2 that on new lead acid batteries which have last about 8 years. that really isn’t out of line for that price and how long they’d last. i’ll have to keep an eye on this and how you like it. maybe i’ll go this way 8 years from now!!
shipping is stupid there though!!
If batteries compared by internal resistance and you don’t rise up voltage, BMS not needed. Else, of course, bms neededNow with these LTO batteries is there some sort of BMS needed?
Battery model: 2.3V 45AhHow is it on fast discharge and low voltages. Like running a electric winch with high electrical demands?
Good quality 105D31R/L batteries costs about 230-250 usd in our local shop.i just spend 1/2 that on new lead acid batteries which have last about 8 years. that really isn’t out of line for that price and how long they’d last. i’ll have to keep an eye on this and how you like it. maybe i’ll go this way 8 years from now!!
I buy 12 pieces 45AH LTO for 491 usd with shipping, 20 usd for cases and 10 usd for aluminium bus.

Lead acid batteries works about 3-5 years in our climate.
Price are same, but LTO lighter, more powerful, more compact.
From Chinese Alibaba marketplace. Batteries new, there are no any scratches or traces of use. Internal resistance 0,3-0,35mOmWhere did you get your cells from? Looks like there's a lot of crappy A-/B quality ones around....I haven't found a clearly reputable source.
No, there are haven’t any protection. It’s just a low level discharge voltage.Thanks for the specs.
It says cutoff voltage around 1.5v is that circuit protection built into the battery or is that something a BMS/protection circuit could do/manage
been learning alot about these batteries.No, there are haven’t any protection. It’s just a low level discharge voltage.
Charging - 6C. 45*6=270A chargingThis one spec really got I'm interested.
6min charge time per cell?
Why?Charging two batteries in parallel will always result in one battery crapping itself eventually. This happens all the time on HDJ81s. Most no start conditions are because of that.
Why?
Well it's funny he said that because I'm certain that all my no start conditions were caused by DRAINING my batteries in parallel!
"...people charge one of the batteries"? In an HDJ-81 the batteries are in parallel all the time except when cranking, thus they drain and charge in parallel vitually at all times. And when you start the engine the 12/24V solenoid puts the batteries in series momentarily then switches back to parallel when it starts (which on most 1HD-Ts is like almost instantaneously).CHARGING batteries in parallel only works long term if the batteries are the exact same capacity, age, condition and quality.
What tends to happen is that people change one of the batteries. This results in unbalanced charging of the batteries and one will drop a cell. Usually this presents as good voltage but can’t supply enough current to crank.

Hence my comment. Why is this the problem with most "no start" conditions on an HDJ in NZ? I'm not talking about dual battery setups here. BTW when you charge an HDJ it's irrelevant which battery you charge. I have seen 12/24V solenoids burn out if you do a lot of winching - Toyota put the OEM winch power wire on the wrong terminal of that12/24 solenoid but that's another discussion.
That said, I can't start mine so I'm off to buy a couple batteries today so I can get it in the garage. Ciao....
