RS3 3 Bank Battery Charger with 2 Bank B.O.S.
This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pro’s RealPRO Series Battery Charger - 18A - 3-6A-Banks - 12V-36V (PN: RS3).
B.O.S. Battery Optimization System - 12V - 2-Bank
B.O.S. actively shuttles energy between batteries to keep “the pack” balanced, increasing battery strength and longevity.
Batteries in a pack will become “out of balance” and the pack is only as good as its “weakest link”. In watercraft applications, this is further compounded when the trolling motor battery is used for peripherals and/or to assist the cranking battery.
B.O.S. actively shuttles energy as needed between batteries wired in series to ensure equal voltage before, during, and after charging.
B.O.S. keeps packs balanced, enabling maximum performance, and quadruple run time on the water.
Premature battery failure due to an unbalanced pack has been, unfortunately, accepted as the ‘norm’ for decades. The B.O.S. answers this call with a BSAP-24 algorithm that can accurately predict and select the battery that needs additional energy to match the other batteries within the pack. This simultaneously and successfully extends the life of each battery in the pack, as well as increasing run times.

- Available in 6V, 8V, and 12V configuration
- Up to six batteries in a series
- Battery Selection and Prediction (BSAP-24) algorithm

Great conclusion to the series.. with an all-star cast involving the extended Bat family.. reminiscent of the "Battle for the Cowl" and "Return of Bruce Wayne" days in scope and back story.. definitely a must-read!

Great story by several great storytellers
Format: Paperback
Picks up where vol1 left off but generally feels more cohesive and organized. Great story by several great storytellers. Connects heavily with Grayson if you want more context.

another chapter in the Batman story
Format: Kindle
Was good but I didn’t love it. There were definitely some high points but I just was not glue reading the next part every time. Some of it was the art teams were also highs and lows. When the art was better I did find myself more engaged with the story. Also to be fair when I read different volumes I have to at time get caught up on which universe version is this going on from. Sometime it can get confusing if your an older read like myself and you have tons of other canon that does always fit in.

An Epic tale and more...
Format: Paperback
I couldn't be happier with this book. Not only does this carry the cosmic Spidey issues that crossed over through the three Spidey books of the time, Amazing, Spectacular, and Web of Spider-Man, but also the 1990 annuals of each book, which had our hero shrunken down to the size of an insect and smaller, fighting alongside Ant-Man against would be technology thieves and then through the Microverse. We have the full annuals so there's even stories featuring Mary Jane, Aunt May, and others in the Spidey universe.
With the inclusion of the Punisher and Venom Amazing Spider-Man issues, it almost feels like three trades in one thick book of Spidey goodness. The art is fantastic also. From Sal Buscema's underrated Spectacular series, to Erik Larsen's Amazing series, and even Todd McFarlane's last Amazing Spider-Man issue where Spidey punches The Hulk so hard, he leaves him orbiting Earth!
While this book has several writers and various other artists, I still find this to be a cohesive collection well worth the price of admission.

Spidey SMASHES Hulk
Format: Paperback
This book presents nearly 500 pages of Spidey Comics from 1989-90, Collecting Amazing Spider-man 326-333 and Annual #24, Spectacular Spider-man 158-160 and Annual #10, and Web of Spider-man 59-61 and Annual #6.
The big event of this comic ties into the much larger Acts of Vengeance story arc. Several supervillains team together, realizing that they've been losing to the same people for 25-30 years. They come up with the idea of trading and going after each other's enemies, thinking that the heroes will not know how to react. (Apparently, it never occurs to them that they will also not really be able to respond to the heroes techniques.) Because Spidey at that point had three magazines a month, that met he'd be hit with three times the rivals.
But after serving the first attack of Graviton, Spidey has an accident that ramps up his powers and makes all attacks on him go very badly for the villain with one villain even getting accidentally killed in the process.
I have to admit that there was something wonderfully pleasing about Spidey knocking around the likes of Magneto and the Hulk like they were rag dolls. Seriously, the first nine issues in this book, are Spidey kicking one threat after another as he has power on par with the Silver Surfer.
We don't learn until the last issue the real reason for the power and longtime readers had to be scared that this was another alien costume, and in a way it was, but if this was like the symbiote, it was a good force that bestowed the uni-power when it was needed. The whole thing has a pretty satisfying ending.
Probably my chief complaint with this book is that the true core of the Cosmic Power ends on page 210, really, AS #329-333 have nothing to do with the Cosmic Powers story and the Annuals are very vaguely related.
AS #329 and 330 is a somewhat violent (but not overly so by today's standards) crossover with the Punisher battling drug cartels and a US government plot to smuggle drugs. The story has some serious moments but ends with one of the goofiest concepts in comics ("Cocaine Standard" 'nuff said). Issues #331-333 is solid story of Eddie Brock/Venom escaping prison and it's interesting in its own right.
There's a three part story spread across all three annuals in which Spider-man is shrinking. At first in the Amazing Spider-man Annual, it looks like it's because of inhaling Ant Man's shrinking gas but it's not that at all as we find out in the other two annuals. The story is decent enough, though Marvel's decision to make people buy all three annuals back in 1990 was somewhat chintzy, though defensible since the story runs 70 pages. For 70 pages, it was good but not great.
However, Marvel actually reprinted everything in the annuals which is a bit of a mixed bag for readers. On one hand, you get the full Annuals with all the extras. On the other, it breaks up the "Spidey's Totally Tiny Adventure Story" and you get a very mixed bag of extras. My thoughts:
"The Mercy Bomb"-A story told in part by Spider-man co-creator Steve Ditko. Seemed to have an anti-war message but didn't tie into anything and was just blah. Grade: D
"A Time to Choose/The Choice":Whatever can be said for spreading the 70 page Spider-man story across three annuals. There was really no reason to break this story of a reformed Sandman facing a tough choice when he's offered a chance to go back to the old life of crime by the Trapster and the Wizard. It's an okay story but seems a little forced. Grade: C+
"Pete and MJ's New Pad"-After the loss of their condo to an unethical real estate developer, Pete and MJ moved into a new apartment. This special feature took a look at the apartment revealing that it's an average apartment with nothing interesting in it. Grade: D
"Amazing Fantasy"- A not so Amazing dream sequence filler. Grade: F
"Pale Reflection"- Former Spider-man villain Hobie Brown goes on a job and learns that he can get beat up. Really? Grade: D-
"What I Did on My Summer Vacation"-A ten page story featuring juvenile delinquent turned crimefighter Rocket Racer, who'd appear in Spider-man: TAS. An okay but not great story. Grade: B
"Sales Day for a Shootout:" Aunt May helps the Punisher kill terrorists. Actually surprised at how positively the Punisher was portrayed in this. Grade: B+
"Eleven Angry Men and One Angry Woman:" This take on Twelve Angry men as Mary Jane as the only hold out on a jury ready to acquit a defendant who claims Spider-man was a thief. There's some humor and a little bit of poignancy. Of course, the wife of Spider-man shouldn't be on this jury but it was a fun story. Grade: A-
"Child Star"-One of the weirder stories in here involves a two year old getting the unipower that Spidey had because a couple summoned demons to help play the stock market. Grade: D
The book ends with material from the first Trade Paperback printing of the main 9 issue Cosmic story which means that you get to find out the background of the book after it's over.
In addition, there's a lot of ongoing plots in this book that were dropped into the middle of because of comic continuity. Joe Robinson is in jail and we really don't know why. Aunt May's friend Nathan is dying but we don't know when she met him or how deep their friendship is. The Black Cat begins to get, well catty, about Peter having married Mary Jane and threatens to break Flash Thompson's (now Peter's best friend) heart out of spite. However, this is just the nature of jumping into an ongoing comic book story.
That said, with all the things I've mentioned, I can't bring myself to rate this less than 4 stars. The core material is awesome and so are most of the actual Spidey stories outside of it, despite the uneven nature of the non-Spidey stories. What's particularly pleasing is seeing the Parker-Watson marriage for fans of that relationship that was abandoned with One More Day. It's not a perfect marriage, but it's clear that it's a positive in Peter's life and it's written way that's not glamorized but is appealing.
If you can take the book's hiccups, this is a good book for teenagers and adults.
